Answer:
Hydrogen is the most explosive element
Answer:
b, decrease in movement of the molecules
Explanation:
removing the energy will begin making the molecules lock up and stop moving due to the loss of energy.

Answer:I believe your answer would be option B) dilute. Hope this helps.
Explanation:
You multiply 32 by 2, since there are two hydrogens in every water molecule.
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
