Answer:

Explanation:
We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
M_r: 32 60
CH₃OH + CO ⟶ CH₃COOH
m/g: 160
(a) Moles of CH₃OH

(b) Moles of CH₃COOH

(c) Mass of CH₃COOH

beryllium, magnesium, strontium,barium<span>, and </span><span>radium. </span>
Balancing redox reactions:
Oxygen should be balanced by adding
as needed, while hydrogen should be balanced by adding
.
What is a redox reaction?
Redox reactions, also known as oxidation-reduction reactions, involve the simultaneous oxidation and reduction of two different reactants.
The Half-Equation Method is one technique used to balance redox processes. The equation is divided into two half-equations using this technique: one for oxidation and one for reduction.
By changing the coefficients and adding
,
, and
in that order, each reaction is brought into equilibrium:
- By putting the right number of water (
) molecules on the other side of the equation, the oxygen atoms are brought into balance. - By adding
ions to the opposing side of the equation, one can balance the hydrogen atoms (including those added in step 2 to balance the oxygen atom). - Total the fees for each side. Add enough electrons (
) to the more positive side to make them equal. (As a general rule,
and
are nearly always on the same side.) - The
on either side must be made equal; if not, they must be multiplied by the lowest common multiple (LCM) in order to make them equal. - One balanced equation is created by adding the two half-equations and canceling out the electrons. Additionally, common terms should be eliminated.
- Now that the equation has been verified, it can be balanced.

As with the properties of a substance, the changes that substances undergo can be classified as either physical or chemical. During physical changes a substance changes its physical appearance, but not its composition. The evaporation of water is a physical change.
(I searched that up but here’s an explanation with my own words that you can use):
Change in matter can be classified as a physical change as well as a chemical change due to the properties of substance. A physical change changes substance within its appearance but not its composition. For an example: The evaporation of water is a physical change.
There you go hopefully that helped
