Question

1,2-dibromoethane ($c_2h_4br_2$) is applied to logs to prevent termite damage. it can be produced by bubbling ethene gas ($c_2h_4$) through a solution of bromine ($br_2$). this chemical reaction is represented by the model below.determine the number of each type of atom in the reactants and products.| | h | c | br || ---- | ---- | ---- | ---- || number of atoms in reactants | $square$ | 2 | $square$ || number of atoms in products | $square$ | 2 | $square$ |

Explanation:

Step1: Identify reactant formulas

Reactants: $\text{C}_2\text{H}_4$ and $\text{Br}_2$

Step2: Count H atoms in reactants

From $\text{C}_2\text{H}_4$: $4$ H atoms

Step3: Count Br atoms in reactants

From $\text{Br}_2$: $2$ Br atoms

Step4: Identify product formula

Product: $\text{C}_2\text{H}_4\text{Br}_2$

Step5: Count H atoms in products

From $\text{C}_2\text{H}_4\text{Br}_2$: $4$ H atoms

Step6: Count Br atoms in products

From $\text{C}_2\text{H}_4\text{Br}_2$: $2$ Br atoms

Answer:

	Number of atoms in reactants	Number of atoms in products
C	2	2
Br	2	2
