Question

Model a synthesis reaction and a decomposition reaction using the following elements. Balance the equations. Calcium Hydrogen Oxygen

Answer 1

By using the elements calcium, hydrogen, and oxygen, we can model a synthesis reaction as 2Ca + H2 → 2CaH2 and a decomposition reaction as 2CaH2 → 2Ca + H2.

Step-by-step explanation:

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. To model a synthesis reaction using calcium, hydrogen, and oxygen, we can write the equation:

2Ca + H2 → 2CaH2

This equation represents the synthesis of calcium hydride (CaH2) from calcium and hydrogen.

A decomposition reaction is a type of chemical reaction where a compound breaks down into two or more simpler substances. To model a decomposition reaction using calcium, hydrogen, and oxygen, we can write the equation:

2CaH2 → 2Ca + H2

This equation represents the decomposition of calcium hydride (CaH2) into calcium and hydrogen.
