What is the law that ensures that chemical reactions are balanced?
aleksley [76]

The law of conservation of mass maintains that in all chemical reactions mass is conserved, this ensures that chemical reactions are balanced.

<h2>What is the law of conservation of mass?</h2>

It is a principle of chemistry that states that the quantities of the masses involved in a given reaction must be constant, that is, the quantity of reactants consumed is equal to the quantity of products formed.

<h3>Characteristics of the law of conservation of mass:</h3>

  • The chemical composition of a substance remains constant.

  • In a chemical reaction certain coefficients are used to balance the equation and this will allow the number of atoms to be equal on both sides.

Therefore, we can conclude that the law of conservation of mass is the one that holds that, within a closed system, the amount of matter before and after a transformation is always the same.

Explain why the catalyst is used as a very fine powder and larger pieces of iron are not used.
Allushta [10]

Answer:

<h2><u>Reason:</u></h2>

Catalyst is used as a very fine powder and larger pieces of iron are not used. This is because the surface area of catalyst needs to be large so that more of the surface is exposed to the substrate and more of the substrate is catalyzed.

<h2><u>Important Info:</u></h2>

=> Larger Pieces of Iron has a smaller surface area than the fine particles.

=> Larger the surface area of catalysts/enzymes , more will be the reaction rate and vice versa.

Hope this helped!

10 Given the balanced ionic equation representing a reaction:
Anon25 [30]

Answer:

Option (A) Each Zn atom loses 2 electrons, and each Co2+ ion gains 2

Explanation:

To know the right answer to the question, let us observe the changes in the oxidation number of Zn and Co. This is illustrated below:

Zn(s) + Co2+(aq) → Zn2+(aq) + Co(s)

The oxidation number of Zn changes from 0 to +2 indicating that Zn has lose 2 electrons.

The oxidation number of Co changes from +2 to 0 indicating that Co has gain 2 electrons.

Therefore, option A is the correct answer.
