What is the final temperature of the solution formed when 1.52 g of NaOH is added to 35.5 g of water at 20.1 [infinity]C in a calorimeter?

NaOH (s) ---> Na +(aq) + OH –(aq) DH = -44.5 kJ/mol

City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city a was 8â° c more than 3 times the temperature of city b. the temperature of city a minus twice the temperature of city b was â’3â° c. what was the temperature of city a and city b on that day? city a was 5â° c, and city b was 4â° c. city a was 3â° c, and city b was â’1â° c. city a was 8â° c, and city b was â’3â° c. city a was 5â° c, and city b was â’5â° c.
