If 6.75 g of NaOH are dissolved in 50.00 g of water and the temperature increases from 20.5°C to 47.8 °C.
a. Is this an example of an endothermic or exothermic reaction?
b. What is the q for the reaction? (Remember since the NaOH dissolves in water add the masses to get the m)
c. How many moles of NaOH are dissolved?
d. What is the ΔH for the reaction?

Define which are endothermic and exothermic NaOH (s) → NaOH (aq) NH4Cl (s) → NH4Cl (aq) CaCl2 (s) → CaCl2 (aq) HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l) NaCl (s) → NaCl (aq)
