5.50 g of sodium hydroxide is dissolved in 175 mL of water. Using a coffee-cup calorimeter, the temperature change of the water is measured to be 2.1°C and the amount of heat absorbed by the water was found to be 11 kJ What is the thermochemical equation for this dissolution?
Question 17 options:
a) NaOH(s) → NaOH(aq) + 1.5 kJ
b) NaOH(s) + 1.5 kJ → NaOH(aq)
c) NaOH(aq) + 11 kJ → NaOH(s)
d) NaOH(s) + 11 kJ → NaOH(aq)
e) NaOH(s) → NaOH(aq) + 11 kJ
