1. The hydrogen ion concentration [H+] is 2.51×10⁻¹² M
2. The hydroxide ion concentration [OH¯] is 3.98×10¯³ M
<h3>1. How to determine the hydrogen ion concentration, [H+]</h3>
From the question given above, the following data were obtained:
- pOH = 2.40
- pH = 14 - pOH = 14 - 2.4 = 11.6
- Hydrogen ion concentration [H+] =?
pH = –Log [H+]
11.6 = –Log [H+]
Multiply through by –1
–11.6 = Log [H+]
Take the anti-log of –11.6
[H+] = anti-log (–11.6)
[H+] = 2.51×10⁻¹² M
<h3>2. How to determine the hydroxide ion concentration, OH¯</h3>
- Hydrogen ion concentration [H⁺] = 2.51×10⁻¹² M
- Hydroxide ion concentration [OH¯] =?
[H⁺] × [OH¯] = 10¯¹⁴
2.51×10⁻¹² × [OH¯] = 10¯¹⁴
Divide both side by 2.51×10⁻¹²
[OH¯] = 10¯¹⁴ / 2.51×10⁻¹²
[OH¯] = 3.98×10¯³ M

Complete Question
Identify whether the following activity on the table shown on the first uploaded image are examples of business level or corporate level strategy
Answer:
The solution to this is shown on the second uploaded image
Explanation:
The explanation is shown on the third and fourth uploaded image
The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder.
2. Because a cumulonimbus cloud is a towering vertical cloud
The answer to this question would be: BaCl 2
Barium is an alkali metal with 56 atomic number. Barium located in the group 2 of the periodic table because it has 2 valence electrons. Chlorine is a nonmetal that has 1 valence electron. When react, it would need 2 chlorine for each barium as the valence electron of barium is twice the chlorine.
