A. is a hypothesis because hypotheses are usually in the form of if-then statements.
The problem with sending a human to jupiter would be the fact that Jupiter has a thing called the red spot which has alot of gravity. The rest of space does not have gravity so there is a natural pull.
<span>If there is more charge in two particles that are different, then they will get a lot closer together than particles that have less charge in them! But if there is more charge in two particles that are the same charge, then they will get a lot further away than particles that have less charge in them.</span>
Answer: <u>2.5 × 10⁻⁵ M H₃O⁺ and 4.0 × 10⁻¹⁰ M OH⁻</u>
Explanation:
∵ pH = - log[H₃O⁺]
∴ 4.6 = - log[H₃O⁺].
∴ log[H₃O⁺] = - 4.6.
∴ [H₃O⁺] = 2.51 x 10⁻⁵.
∵ [H₃O⁺][OH⁻] = 10⁻¹⁴.
[H₃O⁺] = 2.51 x 10⁻⁵ M.
∴ [OH⁻] = 10⁻¹⁴/[H₃O⁺] = 10⁻¹⁴/(2.51 x 10⁻⁵ M) = 3.98 × 10⁻¹⁰ M ≅ 4.0 × 10⁻¹⁰ M.
