Answer:
not sure what to say to this but the rays of the sun contain solar energy which is then converted into energy to use for electrical power
(NH₄)₂CO₃ → 2NH₄⁺ + CO₃²⁻
k=2 k=1
[H+] in first brand:
4.5 = -log([H+])
[H+] = 10^(-4.5)
[H+] in second brand:
5 = -log[H+]
[H+] = 10^(-5)
Difference = 10^(-4.5) - 10^(-5)
= 2.2 x 10⁻⁵
The answer is A.
I believe the answer is D.
