Question

apply the concepts
write the letter of the correct answer on the line at the left.

1. an element is comprised of one type of particle known as

a atoms
b protons
d electrons

1. the ratio of hydrogen (h) atoms to sulfur (s) atoms in sulfuric acid, h₂so₄ is

*note there are 3 different elements represented: hydrogen, sulfur, and oxygen
a 2 to 4
b 1 to 2
c 2 to 1

Explanation:

• For question 14: An element is made up of atoms. Protons are sub - atomic particles within an atom, and electrons are also sub - atomic particles.
• For question 15: In \(H_2SO_4\), the subscript of \(H\) is 2 and the subscript of \(S\) is 1. So the ratio of hydrogen (\(H\)) atoms to sulfur (\(S\)) atoms is \(2:1\).

Answer:

1. A. atoms
2. C. 2 to 1
