Question

Choose a chemical reaction to discuss. Give a balanced equation to represent the reaction, tell the type of chemical reaction it is and give one mole relationship for the reaction. You should have one that is combination, decomposition, single replacement, double replacement, oxidation/reduction, or combustion. Not using: 2H2 (g) + O2 (g) yields 2H2O(g) -OR - N2 + 3H2 yields 2NH3

Answer 1

A) 2H2 + O2 ------> 2H2O

This is combination reaction

2 moles of H2 is reacts with 1 mol of O2 to produce 2 moles of H2O.

B) N2 + 3H2 ----> 2NH3

It is combination reaction.

1 mol of N2 reacts with 3 moles of H2 to produce 2 moles of NH3

Reaction:-

CaCO3 ----> CaO + CO2

This is decomposition reaction

1 mol of CaCO3 is decomposed to give 1 mole CaO and 1 mol CO2.

2Mg + O2 ---> 2MgO

Combination reaction

2 mol of Mg reacts with 1 mol O2 to produce 2 mol MgO.
