Question

benzene (c₆h₆) is used in the production of rubber. it is formed when ethyne (c₂h₂) is heated to a high temperature in an iron tube. this reaction is represented by the balanced chemical equation below.

3c₂h₂ (g) → c₆h₆ (l)

determine the number of each type of atom in the reactants and products.

number of atoms in reactants number of atoms in products
c
h

Explanation:

Step1: Calculate carbon atoms in reactants

In \(3C_2H_2\), for carbon: \(3\times2 = 6\)

Step2: Calculate hydrogen atoms in reactants

In \(3C_2H_2\), for hydrogen: \(3\times2=6\)

Step3: Calculate carbon atoms in products

In \(C_6H_6\), for carbon: \(6\)

Step4: Calculate hydrogen atoms in products

In \(C_6H_6\), for hydrogen: \(6\)

Answer:

	Number of atoms in reactants	Number of atoms in products
H	\(6\)	\(6\)
