what happens when sodium and sulfur combine
Answer:
Sodium sulfide is the chemical compound with the formula Na2S, or more commonly its hydrate Na2S·9H2O. Both the anhydrous and the hydrated salts are colorless solids. They are water-soluble, giving strongly alkaline solutions. When exposed to moist air, Na2S and its hydrates emit hydrogen sulfide, which smells like rotten eggs. Some commercial samples are specified as Na2S·xH2O, where a weight percentage of Na2S is specified. Commonly available grades have around 60% Na2S by weight, which means that x is around 3. Such technical grades of sodium sulfide have a yellow appearance owing to the presence of polysulfides. These grades of sodium sulfide are marketed as 'sodium sulfide flakes'.

Structure
Na2S adopts the antifluorite structure,[2][3] which means that the Na+ centers occupy sites of the fluoride in the CaF2 framework, and the larger S2− occupy the sites for Ca2+.
Production
Industrially Na2S is produced by carbothermic reduction of sodium sulfate often using coal:[4]
Na2SO4 + 2 C → Na2S + 2 CO2
In the laboratory, the salt can be prepared by reduction of sulfur with sodium in anhydrous ammonia, or by sodium in dry THF with a catalytic amount of naphthalene (forming sodium naphthalenide):[5]
2 Na + S → Na2S
Reactions with inorganic reagents
The sulfide ion in sulfide salts such as sodium sulfide can incorporate a proton into the salt by protonation:
S2−
+ H+ → SH−
Because of this capture of the proton ( H+), sodium sulfide has basic character. Sodium sulfide is strongly basic, able to absorb two protons. Its conjugate acid is sodium hydrosulfide (SH−
). An aqueous solution contains a significant portion of sulfide ions that are singly protonated.

Sodium sulfide is unstable in the presence of water due to the gradual loss of hydrogen sulfide into the atmosphere.
When heated with oxygen and carbon dioxide, sodium sulfide can oxidize to sodium carbonate and sulfur dioxide:
2 Na2S + 3 O2 + 2 CO
2 → 2 Na2CO3 + 2 SO2
Oxidation with hydrogen peroxide gives sodium sulfate:[6]
Na2S + 4 H2O2 → 4 H
2O + Na2SO4
Upon treatment with sulfur, polysulfides are formed:
2 Na2S + S8 → 2 Na2S5
Uses
Sodium sulfide is primarily used in the kraft process in the pulp and paper industry.
It is used in water treatment as an oxygen scavenger agent and also as a metals precipitant; in chemical photography for toning black and white photographs; in the textile industry as a bleaching agent, for desulfurising and as a dechlorinating agent; and in the leather trade for the sulfitisation of tanning extracts. It is used in chemical manufacturing as a sulfonation and sulfomethylation agent. It is used in the production of rubber chemicals, sulfur dyes and other chemical compounds. It is used in other applications including ore flotation, oil recovery, making dyes, and detergent. It is also used during leather processing, as an unhairing agent in the liming operation.
Reagent in organic chemistry
Alkylation of sodium sulfide give thioethers:
Na2S + 2 RX → R2S + 2 NaX
Even aryl halides participate in this reaction.[7] By a broadly similar process sodium sulfide can react with alkenes in the thiol-ene reaction to give thioethers. Sodium sulfide can be used as nucleophile in Sandmeyer type reactions.[8] Sodium sulfide reduces1,3-dinitrobenzene derivatives to the 3-nitroanilines.[9] Aqueous solution of sodium sulfide can be refluxed with nitro carrying azo dyes dissolved in dioxane and ethanol to selectively reduce the nitro groups to amine; while other reducible groups, e.g. azo group, remain intact.[10] Sulfide has also been employed in photocatalytic applications.[11]
Explanation:there you go
When sodium combines with sulphur, it formed sodium sulphide. When it interacts with sulfur, polysulfides are produced. Additionally, heat causes sodium sulfide to oxidize fast. Sulfur dioxide and sodium carbonate are the end products.
What is sulphur ?Chemical element sulfur has the letter S and atomic number 16. It is multivalent, nonmetallic, and plentiful. Sulfur atoms normally combine to create cyclic octatomic molecules, which have the chemical formula S₈.
At room temperature, elemental sulfur is a crystalline solid that is brilliant yellow. It is employed in the production of fertilizer, water treatment, mineral extraction, oil refining, and automobile batteries.
Other uses for compounds based on sulfur include vulcanizing rubber, bleaching paper, and producing goods like cement, detergents, and insecticides.
Thus, When sodium combines with sulphur, it formed sodium sulphide.

What is pollen in the reproduction cycle of flowering plants?
A pollen grain is a microspore containing the male gametophyte, usually reduced to two undivided cells, each with one haploid (n) nucleus. These cells are surrounded by a very resistant wall, the exine, which generally has apertures, zones with less resistance which will allow the germination of the pollen tube.
Explanation of the reproduction cycle (cf diagram above)
A given species produces flowers bearing stamens. According to species, these flowers can be unisexual (stamens only) or bisexual (stamens and carpels).
The stamen anthers include 4 pollen sacs containing sporogenous cells (diploid=2n). These sporogenous cells undergo meiosis, each producing 4 microspores (haploid=n). Two nuclei are then formed by mitosis : the vegetative nucleus and the generative nucleus. The latter divides to form 2 sperms. Simultaneously the wall of the microspores becomes thicker and takes the characteristic shape of the species : it is a pollen grain (see: What are the morphological characteristics of pollen and spore grains?). In the majority of species, the 4 grains (resulting from the 4 microspores) split up into single grains; in some cases, they remain together (tetrad = group of 4 grains). When mature, pollen grains are released by the opening of the anthers.
A pollen grain is aimed at reaching another flower of the same species, bearing carpels. The ovaries contain ovules, in which meiosis occurs, then mitoses. It results in an embryo sac with 8 nuclei, among which an egg cell and 2 central cells. When a pollen grain arrives on another flower (see : How are the spores and pollen grains transported?), it is received by the stigmas.
The pollen grain germinates through an opening of the wall: the vegetative nucleus develops into a pollen tube which is guided by the style to the ovary, then enters the micropyle of an ovule. The pollen tube releases 2 sperm nuclei into the ovule: one of the sperms fuses with the egg cell into a zygote (2n), while the other sperm fuses with central nuclei and gives rise to albumen (= food source). There are generally several ovules in an ovary : each one can be fertilized by a distinct pollen grain.
Each fertilized ovule and its albumen form a seed that will develop into a new individual of this species. hope it works

Answer:
Explanation:
En este caso para formular los compuestos, debes identificar el grupo funcional principal de la molecula. Una vez que eso está hecho, puedes intentar formularlo.
Empezaremos primero identificando el grupo funcional principal de la molécula, para luego formularlo correctamente.
Dietil eter: la terminación eter al final significa que pertenece al grupo de los éteres, el cual tiene como formula general R - O - R.
Etanol: debido a que termina en ol, este grupo pertenece a los alcoholes. Para formularlo solo se dibuja la molecula del etano, junto a un enlace con el grupo OH, como su formula general R - OH.
Propanotriol: igualmente termina en ol, por lo tanto es un alcohol, sin embargo, en este caso, tambien tiene la terminación prefija tri, asi que significa que hay 3 grupos OH en la molecula.
Acido propanodioico: esta es sencilla, porque empieza como acido, y solo hay un grupo funcional que empieza así y son los acidos carboxilicos, es decir, el grupo COOH (R - COOH) que es el carboxilo. Tiene el prefijo di, antes del oico, por lo que son dos carboxilos presentes en la molecula.
Pentanal: el sufijo al, significa que pertenece al grupo de los aldehidos, en este caso, posee el grupo carbonilo H - C = O.
Pentano - 2,4 - diona: la terminación ona significa que pertenece al grupo de las cetonas, (R - CO - R), parecido a los aldehidos, con la diferencia de que tiene grupos alquilos en lugar de un hidrogeno.
Metanoato de metilo: la terminación ato de ilo, pertenece a los esteres, (R - COOR) derivado de los acidos carboxilicos.
De aqui en adelante solo mencionaré los grupos funcionales pues ya se explicó el por que, por sus terminaciones:
Ciclohexano - 1.3 - diol: este pertenece a los alcoholes.
Acido heptanoico: acido carboxilico
Ciclobutil metil eter: eteres
Acetato de etilo: ester
2-metilbenzaldehído: aldehído unido a un grupo aromatico como el benceno.
Ciclohexanona: un ciclo (cadena cerrada) unido a un grupo carbonilo.
Butanona: cetona.

project: Modeling Energy Changes
create a model to show how energy changes in a chemical reaction
Answer:
A Chemical reaction involves changes in energy in the form of absorbtion and release of heat due to the formation and breakdown of chemical bonds. A chemical reaction is categoried as endothermic reaction in which heat energy is take in or absorbed and exothermic reaction in which energy is released.
A model can be created by following below details:
Take a beaker and put 10 milliliters of vinegar in it.Place a thermometer in the beaker and measure the initial temperature.Then add half teaspoon of baking soda, that results into decreasing in the temperature.So, the decrease in temperature shows it is an endothermic reaction in which heat energy is absorbed.
Energy change in the reaction has been stored in the products and the reactants. The change in the reactant to product results in a change in energy.
According to the law of conservation of energy, energy can neither be created nor destroyed in a chemical reaction. The chemical reaction has been resulted in the energy change by the endothermic and exothermic reactions.
The project model for energy change can be:
The general model for an endothermic reaction:Reactant + Energy = Products.
The ice cube has been placed in a beaker. It has been consisted of the stored potential energy. WIth the application of heat energy there has been the conversion of ice cubes to the water, and the potential energy of the ice cubes has been converted to the kinetic energy of the moving liquid particles.
The general model for the exothermic reaction:Reactant = Product + Energy
The model has consisted of matching the light with a matchstick. The chemical energy of the stored matchstick has been converted to light and heat energy.

Answer:
Iron is oxidized to form rust.
Explanation:
Consider the reaction; 4Fe + 302------>2Fe2O3, we can see that iron is being oxidized to iron III oxide. Rust is the common name of iron III oxide.
Rusting is an electrochemical process, iron rusts when it comes into contact with air and water because electrochemical cells are set up at the surface of contact.
Iron usually functions as the anode in the electrochemical process. This process leads to the formation of iron III oxide. Rust is soft and breaks off easily thereby exposing the metal below the surface to further rusting.

3. Reaction rates are not dependent on high or low activation energies.
4. Reaction rates are not related to spontaneity.
ANSWER 4
Answer:
the correct choice would be: 4. Reaction rates are not related to spontaneity.
Explanation:
The speed of reaction is independent of spontaneity, since it depends on other factors such as the amount of reagent.
The amount of reagent is one of the variables that most influences the speed of reaction, the greater the amount of reagent, the faster the reaction will be and thus the speed will be increased.

Answer:
1.507 moles of CO₂ are released daily by a hummingbird's respiration
Explanation:
The reaction of production of carbon dioxide and water from sugar is:
C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O
Where 1 mole of sugar produce 12 moles of CO₂
Molar mass of sugar (To convert the mass to moles) is:
12C = 12ₓ12.01g/mol = 144.12g/mol
22H = 22ₓ1.01g/mol = 22.22g/mol
11O = 11ₓ16g/mol = 176g/mol
144.12 + 22.22 + 176 = 342.34g/mol
Thus, moles of 43.0g of sugar are:
43.0g ₓ (1mol / 342.34g) = 0.1256 moles of sugar.
As 1 mole of sugar produce 12 moles of CO₂:
0.1256 moles of sugar ₓ (12 moles CO₂ / 1 mol sugar) =
1.507 moles of CO₂ are released daily by a hummingbird's respiration

The number of atoms in the reactants equals the number of atoms in the products. PLEASE HELP 17 POINTS
Answer:
The number of atoms in the reactants equals the number of atoms in the products.
The correct answer as to which condition must be met in order for an equation to be balanced would be that the number of atoms in the reactants equals the number of atoms in the products.
In a reaction, the law of conservation of matter, mass. or atom must always hold true. For an equation of a reaction to be balanced, the number of atoms of each element in the reactants must equal to the number of atoms of the elements in the products respectively, even though their states might have changed.
For example in the reaction below:
NaOH + HCl ---> NaCl + H2O
The number of atoms of Na, O, H, and Cl on the reactant side is the same as the product side of the equation. The equation is, thus, said to be balanced.
