Interpretation Introduction

(a)

Interpretation:

The formula for each of the reactants and products needs to be identified.

Concept Introduction:

• The formula of a compound is essentially a set of chemical symbols depicting the relative proportion in which the elements combine to form the given molecule.

Interpretation Introduction

(b)

Interpretation:

The given reaction should be balanced by adding appropriate coefficients.

Concept Introduction:

• A chemical reaction is said to be balanced if there are equal number of atoms of a particular kind in the reactants as well as products

Interpretation Introduction

(c)

Interpretation:

The type of the reaction depicted in the diagram needs to be identified.

Concept Introduction:

• Chemical reactions can broadly be classified into 5 types based on how the reactants interact to form products, these include: combination reaction, decomposition reaction, single replacement, double replacement and combustion reaction.
