Calculate the empirical formula for DCBN, given that the percent composition is 48.9%C, 1.76%H, 41.2%Cl, and 8.15%N.

C₇H₃Cl₂N

Explanation:

To determine the empirical formula of DCBN, we need to follow a series of steps.

Step 1: Divide the percent composition of each element by its molar mass

C: 48.9/12.01 = 4.07

H: 1.76/1.01 = 1.76

Cl: 41.2/35.45 = 1.16

N: 8.15/14.01 = 0.582

Step 2: Divide all the numbers by the smallest one

C: 4.07/0.582 ≈ 7

H: 1.76/0.582 ≈ 3

Cl: 1.16/0.582 ≈ 2

N: 0.582/0.582 = 1

The empirical formula of DCBN is C₇H₃Cl₂N

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
