Question

question 9 (1 point) which of the choices is a subscript in 5h₂cl? a 5 b 2 c cl d h question 10 (1 point) which choice is the coefficient in 5h₂cl? a 5 b h c cl d 2

Explanation:

Step1: Define subscript

In a chemical formula, a subscript is a number written below and to the right of a chemical symbol, indicating the number of atoms of that element. In $5H_2Cl$, the number 2 is written below and to the right of H, representing 2 hydrogen atoms.

Step2: Define coefficient

A coefficient in a chemical formula is a number written in front of the formula, indicating the number of formula - units. In $5H_2Cl$, the number 5 is the coefficient.

Answer:

Question 9: B. 2
Question 10: A. 5
