if 10.0 g water at 0.0 celsius is mixed with 20.0 g of water at 30 celsius, what is the final temperature of the mixture?
if 14.3 g of table salt (nacl) is put into 236.0 g of water at 25 degrees celsius, the water cools down when the salt dissolves such that the final temperature is 24.16 degrees celsius. What is the delta H reaction (Kj/mol)? (MMNaCl= 58.44 g/mol) answer is 3.60 kJ/mol, I'm just not sure how to get that
How much heat is required to change 50 g of ice at 0 oC into liquid water at 0 oC? Qmelt ice = cal 2) If 300 g of water initially at 25 oC released the amount of heat that you found in Part (1), what would its temperature be afterward? Tafter = oC 3)If you were to combine 50 g of liquid water at 0 oC with 300 g of the water at the temperature you found in Part...

Eighty grams of cold water initially at 20 oC is combined with some amount of hot water having an initial temperature of 80 oC. Afterward, the final temperature of the mixture stabilizes at 40 oC. Assume the heat is exchanged only between the hot and cold water only (so that there is no heat loss to the surroundings). The specific heat capcity of water is 1.0 cal/(g Co). What was ΔT and Q for the hot water? ΔTH = QH...
