Answer 1

Heya !!!!

★------ Here is your answer -----★

1. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. A reaction is also considered to be a decomposition reaction even when one or more of the products are still compounds.


2. Oxidation is a process which involves addition of oxygen and removal of hydrogen


3 Reduction is a process which involves addition of hydrogen and removal of oxygen

4. CH4 + 2O2 ----> CO2 + 2H20

The substances undergoing reaction are called reactants, and their formulas are placed on the left side of the equation.The substances generated by the reaction are called products, and their formulas are placed on the right sight of the equation.Plus signs (+) separate individual reactant and product formulas, and an arrow (⟶) separates the reactant and product (left and right) sides of the equation.The relative numbers of reactant and product species are represented bycoefficients (numbers placed immediately to the left of each formula). A coefficient of 1 is typically omitted.

Answer 2

Hey mate :-

Ans __________

1 , If mercuric oxide is heated then , mercury and oxygen gas is produced..

HgO ----->> Hg+ O

2 Oxidation is the process of addition of oxygen and removal of hydrogen...

3 Reduction is the process of addition of hydrogen and removal of oxygen...

4 CH4 + 2O2 ---->> CO2 + 2H2O ...

In this product and the reactant is equal..
