Calculate the heat involve 2.0g of (NaOH) undergoes a temperature change of 20°c

Answer 1

We need more information in order to adequately answer this question.

One can use the equation q = mC∆T where q = heat, m = mass, C = specific heat and ∆T = change in temperature. Since we don't have the value of C, we can't solve this. Also, if the 2.0 g of NaOH were dissolved in water, and we wanted to find the heat of solution, we'd need to know how much water was present, then we could solve for q. So, please re-submit or add a comment with additional information.
