(a)
Interpretation: The given set of chemical equations to be determined as a combination reaction, a decomposition reaction or a combustion reaction.
Concept Introduction:
A
Combination reaction is a reaction in which a single product is formed from two or more reactants.
Decomposition reaction is a reaction in which two or more products are obtained from a single reactant. Decomposition reaction is essentially opposite of combination reaction.
Combustion reaction is a reaction in which burning of substance takes place in presence of oxygen. Oxygen is supplied in excess even though the chemical equation for the combustion reaction is balanced. When compound containing carbon, hydrogen and oxygen atom is burnt in presence of oxygen, carbon dioxide and water is obtained as product.
To determine: The given set of reactions as a combination reaction, a decomposition reaction or a combustion reaction.
(b)
Interpretation: The given set of chemical equations to be determined as a combination reaction, a decomposition reaction or a combustion reaction.
Concept Introduction:
A chemical reaction is a process where one or more substances called reactants are converted to one or more different substances called products. The substances considered can either be element or compound.

- 4.69 The pictures below show a molecular-scale view of a chemical reaction between H2 and CO to produce methanol, CH3OH. The box on the left represents the reactants at the instant of mixing, and the box on the right shows what is left once the reaction has gone to completion. Was there a limiting reactant in this reaction? If so, what was it? Write a balanced chemical equation for this reaction. As usual, your equation should use the smallest possible whole number coefficients for all substances.arrow_forward4.8 In an experiment carried out at very low pressure, 13x1015 molecules of H2 are reacted with acetylene, C2H2, to form ethane, C2H6, on the surface of a catalyst.
