Chapter 20, Problem 15PS

Interpretation Introduction

Interpretation:

The mass of hydrogen $H_2$ produced from the reaction of steam with the given substances should be determined.

Concept introduction:

• $\text{Number}\text{of}\text{mole}\text{=}\frac{\text{Given}\text{mass}\text{of}\text{the}\text{substance}}{\text{Molar}\text{mass}}$
• The molar mass of an element or compound is the mass in grams of 1 mole of that substance, and it is expressed in the unit of $gramspermol\left(g/mol\right)$ .
• For chemical reaction balanced chemical reaction equation established in accordance with the Law of conservation of mass.
• Stoichiometric factor is a relationship between reactant and product which is obtained from the balanced chemical equation for a particular reaction.
