Please answer. Thank you for helping me
Instant cold packs used to treat athletic injuries contain solid NH4NO3 and a pouch of water. When the pack is squeezed, the pouch breaks and the solid dissolves, lowering the temperature because of the endothermic reaction NH4NO3(s) + H₂O(1)→ NH4NO3(aq) AH = +25.7 kJ V Part A What is the final temperature in a squeezed cold pack that contains 42.5 g of NH4NO3 dissolved in 125 mL of water? Assume a specific heat of 4.18J/(g° C) for the solution, an initial temperature of 30.0 °C, and no heat transfer between the cold pack and the environment IVE ΑΣΦ 1 F O ?

Incorrect. What is the heat of formation of elements in their standard states? Did you use the correct equation of products minus reactants? The amino acid glycine, C2H5NO2, is one of the compounds used by the body to make proteins. The equation for its combustion is 4C2H5NO2(s) + 902(g) → 8CO2(g) +10H20(1) +2N2(g) For each mole of glycine that burns, 973.49 kJ of heat is liberated. Use this information, plus values of AHº for the products of combustion, to calculate AH° for glycine.

10-A 100.0 mL sample of 0.300 M NaOH is mixed with a 100.0 mL sample of 0.300 M HNO3 in a coffee cup calorimeter. If both solutions were initially at 35.00°C and the temperature of the resulting solution was recorded as 37.00°C, determine the AH°rxn (in units of kJ/mol NaOH) for the neutralization reaction between aqueous NaOH and HNO3. The specific heat capacity of water = 4.18 J/g°C. Assume 1) that no heat is lost to the calorimeter or the surroundings, and 2) that the density and the heat capacity of the resulting solution are the same as water.

How many grams of CaO must be added to 50.0 mL of water to make the temperature increase from 25.0 Â°C to 58.87 Â°C? The reaction is CaO(s) + H 2O(l) ↔ Ca(OH) 2(aq) -- ΔH = -83.7 kJAssume the heat capacity of the solution is the same as pure water (4.184 J/g*Â°C), the density of the solution is 1.00 g/mL and there is no loss of heat to the surroundings.
