Answer:
the answer is 1- loses
Explanation:
When water freezes it gives up some of the water's energy.
Usually you would call this a saturated solution. I hope this helps.
pH solution = 8.89
<h3>Further explanation</h3>
Given
The concentration of HBr solution = 1.3 x 10⁻⁹ M
Required
the pH
Solution
HBr = strong acid
General formula for strong acid :
[H⁺]= a . M
a = amount of H⁺
M = molarity of solution
HBr⇒H⁺ + Br⁻⇒ amount of H⁺ = 1 so a=1
Input the value :
[H⁺] = 1 x 1.3 x 10⁻⁹
[H⁺] = 1.3 x 10⁻⁹
pH = - log [H⁺]
pH = 9 - log 1.3
pH = 8.89
Answer: 92 kg
Explanation:
because the rest of them are increasing weight or not changing at all and if you were to go to the moon you would weigh less
