Question

questions: 1) which of the following statements is not true? a. water is polar. b. water stabilizes temperature. c. water is essential for life. d. water is the most abundant atom in earth’s atmosphere. 2) using a ph meter, you find the ph of an unknown solution to be 8.0. how would you describe this solution? a. weakly acidic

Explanation:

1. Water is a molecule, not an atom. Earth's atmosphere is mostly nitrogen and oxygen atoms, so "Water is the most abundant atom in Earth’s atmosphere" is false.
2. pH > 7 indicates a basic solution; pH 8.0 is weakly basic.

Answer:

1. d. Water is the most abundant atom in Earth’s atmosphere.
2. (Assuming the intended correct option, e.g., "Weakly basic" if provided; based on pH 8.0, the solution is basic.)
