The value of ΔH° for the reaction below is -126 kJ. The amount of heat that is released by the reaction of 30.0 g of Na2O2 with water is kJ. 2Na2O2 (s) + 2H2O (l) → 4NaOH (s) + O2 (g) A -126 B 24.2 C 67.5 D 48.4 E 96.9

Which of the following statements is true? question 4 options: nuclear decay rates vary with the conditions of the reaction, but chemical reaction rates do not. chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates do not. neither chemical reaction rates nor nuclear decay rates vary with the conditions of the reaction. both chemical reaction rates and nuclear decay rates vary with the conditions of the reaction.

Why doesn't heat added to water make the tempature rise above 100c
