Question

what is the correct ratio of the atoms of the two elements present in a sample of the compound copper chloride, cucl₂? each answer will be formatted as copper : chlorine. select one: a. 0:0 b. 2:1 c. 1:2 d. 1:1 in the molecule represented by the chemical formula h₂so₄, there would be... select one: a. 1 hydrogen atom b. 2 hydrogen atoms c. 2 sulfur atoms d. 4 sulfur atoms

Explanation:

Step1: Analyze CuCl₂ subscripts

In $\text{CuCl}_2$, Cu has no subscript (implied 1), Cl has subscript 2. Ratio = 1:2.

Step2: Analyze H₂SO₄ subscripts

In $\text{H}_2\text{SO}_4$, H has subscript 2, so there are 2 H atoms.

Answer:

1. c. 1:2
2. b. 2 hydrogen atoms
