Answer:

Explanation:
Hello!
In this case, since the energy implied in a heating process is computed by using the following equation:

Whereas m is the mass, C the specific heat and T the temperature. In such a way, by plugging in the given mass, specific heat and temperatures, we obtain the following energy:

Considering that the specific heat can by used by unit of °C or K because their difference is equivalent.
Regards!
I think it would be the sun because it’s the one giving energy to most things, and if you haven’t answered it yet you can put the sun because it’s giving energy to the plans and the environment and it’s the the sun was the effect of the whole thing, sorry if I didn’t help

Hello.
He have that:
[H+][OH-] = 10⁻¹⁴
3.64 x 10⁻⁸ [OH-] = 10⁻¹⁴
[OH-] = 0.27 x 10⁻⁶ mol/L
