A cold pack contains 130.9 g of water and 41.3 g of ammonium nitrate. What will be the final temperature of the activated cold pack, if the initial temperature is 28 °C? (Assume that the specific heat of the solution is the same as that for water, 4.184 J/g ⋅ °C and no heat is lost). The heat of solution of ammonium nitrate is 25.4 kJ/mol.
From the table of standard heats of formation, AHf, attached to the directions of this assignment, calculate the AH for the combustion of ethanol. C₂H5OH(I) + 30₂(g) 2CO2(g) + 3H2₂O(1) Please do not include units in your answer. Answer must include proper sign and significant figures. Make sure you pay attention to the sign and include the sign if applicable. You always need to include the sign for ΔΗ.
