Q. 13 - An Introduction to General, Organic, and Biological Chemistry

Question

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

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.

Step-by-Step Solution

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 1: Given information

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

Step 2: 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 ${\mathrm{AB}}_3$.

Step 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. 

Step 4: 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 $2 \mathrm{A}+3{ \mathrm{B}}_2\to 2{\mathrm{AB}}_3$.

Step 5: 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.

Step 6: 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.
