They have the same amount but if you count the wrist it was more then the leg and ankle.

In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.
What is the concentration of H+ ions at a pH = 2?
<h3>
0.01 mol/L </h3>
What is the concentration of OH– ions at a pH = 2?
<h3>
0.000000000001 mol/L
</h3>
What is the ratio of H+ ions to OH– ions at a pH = 2?
<h3>
10,000,000,000 : 1</h3>

I LITERALLY spent 40 MINUTES trying to figure out this question, so please, use my VERY CORRECT answers!
<em>I hope this helps!</em>
CH₃-CH=CH₂ propene

<u>Answer:</u> The correct answer is Option 1, Option 2 and Option 3.
<u>Explanation:</u>
A base is defined as the substance which releases hydroxide ion when dissolved in water.
For the given options:
- <u>Option 1:</u>
When ammonia is dissolved in water, it produces ammonium hydroxide which forms a basic solution.
- <u>Option 2:</u>
When sodium oxide is dissolved in water, it produces ammonium hydroxide which forms a basic solution.
- <u>Option 3:</u>
When lithium hydroxide is dissolved in water, it produces aqueous lithium hydroxide which forms a basic solution.
- <u>Option 4:</u>
When phosphorus pentoxide is dissolved in water, it produces phosphoric acid which forms an acidic solution.
Hence, the correct answer is Option 1, Option 2 and Option 3.
For the first question it would be a unit obtained from the change in velocity per unit of time or m/s^2.
The vf and vi represent the final and initial velocity of the object and or item.
Knowing the formula for acceleration is simply change in velocity divided by time
Vi = 0
Vf = 27 m/s
t = 10 s
Vf = vi + at
27 = 10a
a = 27/10 or 2.7 m/s^2.
