Composition of matter (compound, mixture, element)
Explanation:
Matter can be classified into two broad categories: pure substances and mixtures. ... A material composed of two or more substances is a mixture. Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an elementOne useful way of organizing our understanding of matter is to think of a hierarchy that extends down from the most general and complex to the simplest and most fundamental (Figure 3.4.1 ). Matter can be classified into two broad categories: pure substances and mixtures. A pure substance is a form of matter that has a constant composition (meaning that it is the same everywhere) and properties that are constant throughout the sample (meaning that there is only one set of properties such as melting point, color, boiling point, etc. throughout the matter). A material composed of two or more substances is a mixture. Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen. Today, there are about 118 elements in the known universe. In contrast, scientists have identified tens of millions of different compounds to date.
An element is a substance which can be split into simpler unit by ordinary chemical prcess.
Compound this is a pure substance that is composed of two or more element in a fixed and definite portion.
Mixture contains two or more constituents which can be easily separated by physical method.
How do i caculate speed
Answer:
Speed uses the same units as velocity, which is meters divided by seconds (m/s)(It doesn't need to be m/s, but it's the most common unit. It's basically any unit of length divided by any unit of time)
hope this helps and good luck
Answer/Explanation:
Speed is a force and is solved by using acceleration.
You can use the problem to solve for force:
F= MA or Force equals mass times acceleration.

Define Triple point of water?
Triple point is that temperature, at which the substance is found in all three states i.e. solid, liquid and gas. Every substance has different triple point, because Triple point is just above the freezing point and each substance has different freezing and boiling point.
_____________________________________WATER:Water has a Melting point or Freezing Point (MP or FP) of [tex]0^0[/tex] C or 273K and Boiling point (BP) [tex]100^{0}[/tex] C or 373 K. Since the triple point is just above the MP or FP thus Triple Point of water is [tex]0.01^{0}[/tex]C or 273.16K.

Gas, liquid, and plasma
Explanation:
Answer:
Liquid, Gas and Plasma
Explanation:
➨Think about it like this if you put a material made out of these and flipped it over which one would have the most effect of change in shape?
▶Liquid molecules slide past each other meaning they are not held in place.
▶Gas molecules are "excited" they bounce around everywhere meaning they are not held in place.
▶Plasma has no fixed shape or volume so it cant be held in place!
▶Solid molecules have a fixed shape so they cannot move on their own.

A teacher wrote the following part of a balanced chemical equation:Cu + 2AgNO3 →To show the conservation of matter in the chemical reaction, how many silver (Ag) atoms will be needed on the right-hand side of the balanced equation?
Answer:
Figure 7.4.1 : Balancing Equations. You cannot change subscripts in a chemical formula to balance a chemical equation; you can change only the coefficients. Changing subscripts changes the ratios of atoms in the molecule and the resulting chemical properties. For example, water (H2O) and hydrogen peroxide (H2O2) are chemically distinct substances. H2O2 decomposes to H2O and O2 gas when it comes in contact with the metal platinum, whereas no such reaction occurs between water and platinum. The subscripts are part of the formulas and once the formulas for the reactants and products are determined, the subscripts may not be changed. The coefficients indicate the number of each substance involved in the reaction and may be changed in order to balance the equation. The equation above indicates that one mole of solid copper is reacting with two moles of aqueous silver nitrate to produce one mole of aqueous copper (II) nitrate and two atoms of solid silver.

a R= element s = compound t = mixture
b R= compound s = element T= mixture
cR= element s = mixture t= compound
d r = mixture s= emelem t = compound
ASAP
Answer:
d
Explanation:
The correctly describes the gases in containers R, S, and T is R = mixture S = element and T = compound. Hence option d is correct.
What are gases?Gases are defined as the state of matter where particles often travel very swiftly, far apart from one another, and with little or no attraction to one another. They take up much more space than the liquids or solids from which they are formed, are simple to compress, and expand to fill their containers.
Particles make up all matter; these particles can be single atoms or atoms that have been chemically combined to form molecules. This fact allows us to divide matter into three general categories: elements, compounds, and mixtures. All the atoms in an element are of the same kind. A compound is created when more than one kind of atom is chemically bonded.
Thus, the correctly describes the gases in containers R, S, and T is R = mixture S = element and T = compound. Hence option d is correct.

Explanation:
secondary alcohol (X) reacts with PCL5 to give alkyl halide (Y) which on dehydrohalogenation yield an alkene(Z).The alkene upon ozonolysis gives the mixture of ethanal and methanal.Identify X ,Y ,Z
Answer:
X = 2-propanol
Y = 2-chloropropane
Z = propene
Explanation:
Secondary alcohol is an alcohol in which the carbon that the functional group (OH group) is attached to is also attached to two alkyl group. Examples are 2-propanol and 2-butanol.
The secondary alcohol referred to in the question here is 2-propanol and it reacts with PCl₅ as seen below
H₃C-CH-CH₃ + PCl₅ ⇒ H₃C-CH-CH₃ + HCl + POCl₃
| |
OH Cl
The alkylhalide produced there is 2-chloropropane. Thus, we can see that X is 2-propanol and Y is 2-chloropropane.
When this 2-chloropropane undergoes dehydrohalogenation (removal of hydrogen and halogen) an alkene is formed. The reaction is seen below
H₃C-CH-CH₃ (-HCl) ⇒ H₃C-CH=CH₂
|
Cl
The alkene produced (as seen above) is propene.
Confirmation: When propene undergoes ozonolysis, the compounds produced are ethanal and methanal as seen in the equation below

Sulfur dioxide is an atmospheric pollutant.
Sulfur dioxide pollution is reduced by reacting calcium oxide with sulfur dioxide to
produce calcium sulfite.
CaO + SO2 → CaSO3
7.00 g of calcium oxide reacts with an excess of sulfur dioxide.
Relative atomic masses (Ar): O = 16 S = 32 Ca = 40 Calculate the mass of calcium sulfite produced
The mass of calcium sulfite produced : 15 g
Further explanationA reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
CaO + SO₂ → CaSO₃
mol CaO (MW=56 g/mol)
[tex]\tt \dfrac{7}{56}=0.125[/tex]
Because sulfur dioxide is an excess, so mol CaSO₃ based on mol CaO
From the equation, mol ratio of mol CaSO₃ : mol CaO=1 : 1, so mol CaSO₃ :
[tex]\tt \dfrac{1}{1}\times 0.125=0.125[/tex]
mass CaSO₃ (MW=120 g/mol) :
[tex]\tt 0.125\times 120=15~g[/tex]
How would the calculated concentration of the hci be affected if the sodium hydroxide were poured from ma beaker that contained some water before the naoh were added to it
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, the beaker that contained some water before NaOH were added means that the resulting solution in that beaker will be more dilute. When this diluted sodium hydroxide solution is added to HCl (not hci), the reaction below occurs
HCl + NaOH ⇒ NaCl + H₂O
The reaction above is a neutralization reaction. The concentration of the acid (HCl) will reduce when a base (sodium hydroxide) is added and will also reduce more because of the presence of more water (in the base) which normally reduces the concentration of ions present in an acid or a base to become more dilute.
