Answer this question… Which of the following best describes a neutralization reaction? A. Acid + base H+ + OH- B. Acid + base salt + water C. Acid + base metal + nonmetal D. Acid + base H2O + H3O+
It represents the change in enthalpy for the reaction.
It gives off heat as a product.
It is multiplied by 2 if the intermediate reaction is multiplied by 2
Grams solid mol/g Hfusion
Hreaction = Hf, products - Hf, reactants
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
A+B —> C+D+ HEAT (Apex)
1kJ x 1/Hvap x g/mol liquid
The enthalpy of reaction is the change of the system enthalpy after a chemical reaction.
Brainly says it’s energy profile B for APEX please correct if i’m wrong.
H2(g) + S(s) —> H2S + 20.6 kJ
