80.0mL of a 1.00M HCl solution at 20.00Celsius is mixed with 80.0mL of a 1.00M Ca(OH)2 solution at 20.00 Celsius. If the final temperature of the mixture is 35.00*C, determine the heat of neutralization in kJ/mole. Assume a density of 1.00 g/cm3 and a specific heat of 4.184 J/goC. How do I approach this step by step?

The characteristic of two different types of reactions are shown below. reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of and element. which statement is true about the atoms of the elements that participate in the two reactions? a: their identity changes in both reaction a and b. b: their identity changes in reaction a but not b. c: their identity changes in reaction b but not a. d: their identity remains the same.
