a. Write the formulas for each of the reactants and products.

b. Write a balanced chemical equation for the reaction.

c. Indicate the type of reaction as combination, decomposition, single replacement, double replacement, or combustion.

Short answer

Part (A)

a) The formulas of the reactants are $A$and ${\mathrm{B}}_2$,

The formula of the product is ${\mathrm{AB}}_3$.

Part (B)

b) The Balanced Chemical Equation of the Reaction is

$2\mathrm{A}+3{\mathrm{B}}_2\to 2{\mathrm{AB}}_3$.

Part (C)

c) The Given reaction indicates as Combination Reaction.

Step-by-step solution

Given information

In the following diagram, blue spheres represent the element A and yellow spheres represent the element B:

Formulas of Reactants and Products 

• Component A responds with component B.
• There are four components of $A$and six elements of $B$in the reactants.
• Component $A$is monoatomic, while component $B$is diatomic.
• The item component contains one component of $A$and three components of $B.$
• Therefore, the formulas of the reactants are $A$and ${\mathrm{B}}_2$, and the formula of the product is ${\mathrm{AB}}_3$.

Balanced Chemical Reaction (Part B)

• In the balanced chemical equation, the number of atoms in each element is equal on the left and right sides of the reaction.

Balanced Chemical Equation for the Reaction

• The six elements of ${\mathrm{B}}_2$combine with four elements of $\mathrm{A}$.
• The reaction can be expressed as $4\mathrm{A}+6{\mathrm{B}}_2\to 4{\mathrm{AB}}_3$.
• The reaction needs two elements of $\mathrm{A}$and three elements of ${\mathrm{B}}_2$,
• Therefore, the balanced chemical reaction is $2\mathrm{A}+3{\mathrm{B}}_2\to 2{\mathrm{AB}}_3$.

Type of Reaction (Part C) 

• Many chemical reactions fall into one of five basic types.
• The five basic types of chemical reactions are combination, decomposition, Single Replacement, Double Replacement and combustion.

Combination Reaction

• The given reaction indicates Combination Reaction When two or more elements combine to form a product, the reaction is called a binding reaction.
• Therefore, the reaction is a combination reaction.
