Answer:
i have no answer for part A
part B
the one that has a 4 can be divided by 2 because reducing
part c
you can determine if an equation is written in the correct way by balancing the equation as if it had not been done already.
The hydronium ion concentration of a pH = 9.2 of solution is 6.3 × 10⁻¹⁰M.
<h3>How do we calculate pH?</h3>
pH of the solution is define as the negative logarithm of the concentration of the hydronium ion as:
pH = -log[H⁺]
Or [H⁺] =
Given that pH value = 9.2
On putting values, we get
[H⁺] = = 6.3 × 10⁻¹⁰M
Hence required concentration of hydronium ion is 6.3 × 10⁻¹⁰M.

Answer:
This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against the fabric they become negatively charged. They take some of the electrons from the fabric and leave them positively charged.
Explanation:
Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.
