At 1.01 bar, how many moles of CO2 are released by raising the temperature of 1 litre of water from 20∘C to 25∘

Reactions between acids and bases (neutralization reactions) are exothermic. You have a solution of an acid and a solution of a base, both at 23oC. If you mix the two solutions together, would you expect the final temperature to be greater or less than 23oC?

In a constant‑pressure calorimeter, 65.0 mL65.0 mL of 0.330 M Ba(OH)20.330 M Ba(OH)2 was added to 65.0 mL65.0 mL of 0.660 M HCl.0.660 M HCl. The reaction caused the temperature of the solution to rise from 22.07 ∘C22.07 ∘C to 26.57 ∘C.26.57 ∘C. If the solution has the same density and specific heat as water (1.00 g/mL1.00 g/mL and 4.184J/g⋅°C,)4.184J/g⋅°C,) respectively), what is Δ?ΔH for this reaction (per mole H2OH2O produced)? Assume that the total volume is the sum of the individual volumes.

Zinc metal reacts with HCl according to the following balanced equation: Zn(s) + 2HCI(aq) --> ZnCl2(aq) + H2(g) When 0.140 grams of Zn(s) is combined with an excess amount of HCI to make 50.0 mL of solution in a coffee-cup calorimeter, all the zinc reacts, raising the temperature of the solution from 21.60°C to 24.60°C. Find AH for this reaction in kJ/mol. Assume the density of the solution is 1.00 g/mL and the specific heat capacity of the solution is 4.184 J/g°C. Use an atomic weight of 65.38 g/mol for Zn Hints: -q(reaction) = q(solution) %3D AH = q/mol of limiting reagent %3D Do not type units with your answer.
