Chapter 4, Problem 94GQ

Interpretation Introduction

Interpretation:

The metal in the given reaction has to be identified.

Concept introduction:

• The number of moles of any substance can be determined using the equation.

  $\text{Number}\text{of}\text{mole}\text{=}\frac{\text{Given}\text{mass}\text{of}\text{the}\text{substance}}{\text{Molar}\text{mass}}$

• 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 grams per mol (g/mol).
• $\text{Molar}\text{mass}=\frac{\text{Given}\text{mass}\text{of}\text{the}\text{substance}}{\text{Mole}\text{of}\text{the}\text{substance}}$
• For chemical reaction balanced chemical reaction equation written in accordance with the Law of conservation of mass.
• Law of conservation of mass states that for a reaction total mass of the reactant and product must be equal.

Barium (option d) is the metal involved in the given reaction.
