Chapter 14, Problem 27CI

Interpretation Introduction

(a)

Interpretation:

The balanced chemical reaction between metal and hydrogen chloride needs to be determined.

Concept Introduction:

Metals are electropositive elements which react with dilute acids to release hydrogen gas. The reaction leads to the formation of metal compound with hydrogen gas. This property can be used to distinguish metals from non-metals as non-metals cannot release hydrogen gas with acids.

The chemical equation is said to be balanced if the number of atoms of same element are equal in both sides of the reaction arrow.

Interpretation Introduction

(b)

Interpretation:

The volume of hydrogen gas needs to be calculated.

Concept Introduction:

The molarity of the solution is defined as number of moles of solute in 1 L of the solution. It is mathematically represented as follows:

  $M=\frac{n}{V\left(L\right)}$

Here, n is number of moles, V is volume of solution in L.

Interpretation Introduction

(c)

Interpretation:

The number of moles of metal M reacted needs to be calculated.

Concept Introduction:

Metals are electropositive elements which react with dilute acids to release hydrogen gas. The reaction leads to the formation of metal compound with hydrogen gas. This property can be used to distinguish metals from non-metals as non-metals cannot release hydrogen gas with acids.

Interpretation Introduction

(d)

Interpretation:

The molar mass and name of metal needs to be determined.

Concept Introduction:

Metals are electropositive elements which react with dilute acids to release hydrogen gas. The reaction leads to the formation of metal compound with hydrogen gas. This property can be used to distinguish metals from non-metals as non-metals cannot release hydrogen gas with acids.

Interpretation Introduction

(e)

Interpretation:

After the identification of the metal, the balanced chemical equation for the reaction needs to be written.
