What variable represents specific heat in the equation q = mct?

The "c" represents in specific heat in this question.

Q is the total energy, m is the mass, c is the specific heat capacity, and t is the temperature change. This equation is the equation for calculating about the total energy given out of absorbed when a temperature of a substance changes.

For example, if we want to know how much heat is absorbed by 1 kg of water for it to rise by 10 degrees, we can calculate by using the specific heat of water, which is around 4200 J kg-1 °C-1. So the total heat absorbed would be 1 x 4200 x 10 = 42000 J.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
