C. All of their chemical products are gases found in the atmosphere.
O D. The chemical products of one are the reactants of the other.
Answer: D. The chemical products of one are the reactants of the other.
I just took the quiz
Cellular respiration and photosynthesis related as the chemical products of one are the reactants of the other and the correct option is option D.
What is the difference between Respiration and Photosynthesis?Respiration is something that occurs in all living organisms. Thus, it is a process that converts oxygen and glucose into carbon dioxide and water and ultimately makes energy for your body cells.
On the other hand, photosynthesis takes place in green plants that contain chlorophyll. In this process, they make use of sunlight and water for converting it into energy.
Plants release oxygen which is a by-product of photosynthesis, and we breathe in oxygen so that our cells can carry out cellular respiration and generate ATP.
Therefore, Cellular respiration and photosynthesis related as the chemical products of one are the reactants of the other and the correct option is option D.

a 5 g ice cube starts life at -1 C if 2182.5 j are added to it what will be the final temperature upon his demise ?
Answer:
Final Temp = 23.92°C
Explanation:
ΔH(total) = (m·c·ΔT)ice + (m·ΔH(f))melt'g + (m·c·ΔT)water
2182.5j = (5g)(2.092j/g·°C)(1°C) + (5g)(334.56j/g) + (5g)(4.184j/g·°C)(ΔT)
(2182.5 - 10.46 - 1672.8)j = 20.92j/°C·ΔT
ΔT = (2182.5 - 10.46 - 1672.8)j / 20.92j/°C = 23.92°C
Since the melting ice starts and ends at 0°C and is then warmed to 23.92°C then the temperature change is also the final temp of the water based upon given energy input values.

De una misma estación salen, en el mismo instante, dos trenes, con velocidades constantes de 72 y 90 [km/h]. ¿Qué distancia separa ambos trenes luego de 2 horas de viaje si se mueven en la misma dirección ... a) ... Y en el mismo sentido de circulación?
Answer:
144 km y 180 km respectivamente.
Explanation:
¡Hola!
En este caso, dado que tenemos dos trenes con velocidades diferentes, es posible multiplicar la velocidad de cada tren por el tiempo común, con el fin the hallar la distance recorrida; es de entender, que a mayor velocidad, mayor distance ha de recorrer el tren:
[tex]d_1=72km/h*2h=144km\\\\d_2=90km/h*2h=180km[/tex]
Así, entendemos que el tren número 1 recorre 144 kilómetros, mientras que el tren número 2, 180 kilómetros.
¡Saludos!
Which statement describes the Arrhenius interpretation of acids and bases?
It has a wider range of applications than the Bronsted-Lowry interpretation.
It has a wider range of applications than the Lewis and Bronsted-Lowry interpretations.
It is used in situations that involve bases that do not produce hydroxide ions.
It is limited to situations that involve aqueous solutions or specific compounds.
Answer: Composition is an orderly arrangement of visual structures (elements and principles) to create a mood, add meaning and direct the viewers' attention to the purpose of the artwork. Compositions are said to be 'designed' according to the specific intent of the artist.
The statement that describes the Arrhenius interpretation of acids and bases is that it is limited to situations that involve aqueous solutions or specific compounds. Therefore, option D is correct.
What is Arrhenius's interpretation?Arrhenius's interpretation defined an acid as a substance that increases the concentration of hydrogen ions (H⁺) when dissolved in water and a base as a substance that increases the concentration of hydroxide ions (OH⁻) when dissolved in water.
According to Arrhenius's interpretation, when an acid is dissolved in water, it releases H⁺ ions, which then react with water molecules to form H₃O⁺ ions, also known as hydronium ions.
Similarly, when a base is dissolved in water, it releases OH⁻ ions, which then react with water molecules to form H₂O molecules and more OH⁻ ions. Thus, option D is correct.

What are the characteristic property's of metals such as malleability and high conductivity are due to ?
Answer:
Metallic Bonding
Explanation:
Conductivity occurs when electrons or ions are free moving. The conductivity in metals is due to electrons being delocalized in a sea of electrons. Metals contain metallic bonding which allows the electrons to freely move.
Malleability happens when adjacent layers of positive ions move relative to one another while being in contact with the sea of electrons from the metallic bonding.

Which of the following ions will form the weakest bond with Na+?
Br^-
F^-
CI^-
I^-
Answer:
Iodide ion, I- will form the weakest bond with sodium ion, Na+
Explanation:
Electronegativity is the ability with which a neutral atom attracts electrons to itself.
The electronegativity of the halogens decrease on going down the group among the halogens. This is is because on going down the group, the atomic size as well as ionic size of the atoms in the group increases. This increase decreases the effect of the attraction of the positive nucleus on the electrons. Thus, valence electrons can be more readily removed.
The transfer of electrons from metallic sodiummto a halogen results in annionic bond between the two atoms. The strength of the ionic bond decreases on going down the group due to decrease in electronegativity. Thus, iodide ion, I-, which is the least electronegative among the given options will form the weakest bond with Na+.
A reaction in the laboratory yields 5.98 g KAI(SO2)2, How many moles of potassium aluminum
sulfate were produced?
Answer:
0.0308 mol
Explanation:
In order to convert from grams of any given substance to moles, we need to use its molar mass:
Molar mass of KAI(SO₂)₂ = MM of K + MM of Al + (MM of S + 2*MM of O)*2Molar mass of KAI(SO₂)₂ = 194 g/molNow we calculate the number of moles of KAI(SO₂)₂ contained in 5.98 g:
5.98 g ÷ 194 g/mol = 0.0308 mol2C(s) + 2H2(g) → C2H4(g): ΔH = +52.4 kJ/mol

A sample of pure KHC8H4O4 weighing 1.518 grams was dissolved in water and titrated with the NaOH solution. To reach the equivalence point, 26.90 milliliters of base was required. Calculate the molarity o
Answer:
0.2763M NaOH
Explanation:
Based on the reaction of hydrogen phtalate, KHP, with sodium hydroxide, NaOH:
KHP + NaOH → KNaP + H₂O
1 mole of KHP reacts per mole of NaOH.
In the equivalence point, the moles of NaOH added = Moles of KHP that were dissolved.
Thus, to solve this question, we must find the moles of KHP = Moles NaOH. With the moles and the volume of NaOH required to reach the equivalence point we can find molarity of NaOH solution:
Moles KHP = Moles NaOH (Molar mass KHP = 204.22g/mol):
1.518g * (1mol / 204.22g) = 7.433x10⁻³ moles NaOH
In 26.90mL = 0.0269L:

Answer: 824.6 g of NaCl are produced from 500.0 g of chlorine.
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex] [tex]\text{Moles of} Cl_2=\frac{500.00g}{71g/mol}=7.04moles[/tex]
[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]
According to stoichiometry :
1 mole of [tex]Cl_2[/tex] produce = 2 moles of [tex]NaCl[/tex]
Thus 7.04 moles of [tex]Cl_2[/tex] will produce=[tex]\frac{2}{1}\times 7.04=14.08moles[/tex] of [tex]NaCl[/tex]
Mass of [tex]NaCl=moles\times {\text {Molar mass}}=14.08moles\times 58.5g/mol=824.26g[/tex]
Thus 824.6 g of NaCl are produced from 500.0 g of chlorine.

The electronic configuration is used to explain the orbitals of an atom and it helps to determine the physical and chemical properties of the elements. The electronic configuration of zinc is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰. The correct option is C.
What is electronic configuration?The distribution of electrons in the atomic orbitals is given by the electronic configuration. It is a standard notation in which all the electrons holding atomic subshells are arranged in a sequence. Each element has a unique electronic configuration.
The electronic configuration of an element can be written in two ways, in standard notation, and in condensed form. In the case of elements with larger atomic numbers, the electronic configuration becomes lengthy in standard notation. So in such cases condensed form is generally used.
In condensed form electronic configuration of zinc is [Ar] 3d¹⁰4s² and in standard form it is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰.
Thus the correct option is C.
