33. Convert the following word equations into balanced formula equations
a. Potassium chloride Potassium chloride + Oxygen
b. Zinc + Sulphuric acid --Zinc sulphate + Hydrogen
c. Calcium carbonate calcium oxide + carbon dioxide
34. Derive Fama where all symbols have their usual meaning.​

a. KClO₃ ⇒ KCl + 1.5 O₂

b. Zn + H₂SO₄ ⇒ ZnSO₄ + H₂

c. CaCO₃ ⇒ CaO + CO₂

Explanation:

We will convert the following word equations into formula equations and then balance them using the trial and error method.

a. Potassium chlorate (I fixed a mistake here) ⇒ Potassium chloride + Oxygen

KClO₃ ⇒ KCl + O₂

We can balance this equation by multiplying O₂ by 1.5.

KClO₃ ⇒ KCl + 1.5 O₂

b. Zinc + Sulphuric acid ⇒ Zinc sulphate + Hydrogen

Zn + H₂SO₄ ⇒ ZnSO₄ + H₂

This equation is already balanced.

c. Calcium carbonate ⇒ calcium oxide + carbon dioxide

CaCO₃ ⇒ CaO + CO₂

This equation is already balanced.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
