Answer:
The answer is B (25%)
Explanation:
I think the answer is this because it's the smallest value in the options, and if you choose 0% the answer would be wrong.
Answer:
[H+] = 1.66 x 
Explanation:
To find the [H+] concentration of a solution, we can use the formula:
![[H+] = 10^{-pH}](https://tex.z-dn.net/?f=%5BH%2B%5D%20%3D%2010%5E%7B-pH%7D)
Let's plug in the pH.
![[H+] = 10^{-3.78}](https://tex.z-dn.net/?f=%5BH%2B%5D%20%3D%2010%5E%7B-3.78%7D)
Evaluate the exponent.
[H+] = 1.66 x 
Hope this helps!
C) is correct, because there are 2 carbons and 4 oxygens on both sides, making the equation balanced.
