What's the difference when calculating molar heat capacity and just heat capacity?
THERMOCHEMISTRY Calculating molar heat capacity A chemist carefully measures the amount of heat needed to raise the temperature of a 762.0 mg sample of CHF, from 0.8 °C to 14.2 "C. The experiment shows that 14.8 J of heat are needed. What can the chemist report for the molar heat capacity of CHF,? Round your answer to 3 significant digits. mol. x ? Explanation Check

An ideal monatomic gas has a molar heat capacity Cmp at constant pressure. What is the molar heat capacity at constant volume of an ideal diatomic gas?
The constant volume Molar heat capacity of ethane, C2H6(g) is 44.3 J/mol-K. When 9.0 kJ of heat is removed at constant volume from 90 grams of ethane, the final temperature is 53oC. What was the approximate initial temperature of the C2H6 before the heat is removed. The correct answer is +120oC. Please show work and explain
1) Define the terms: heat, enthalpy of reaction, heat capacity, specific heat capcity. Explain the difference between an endothermic and exothermic reaction. What is the heat of neutralization?

3,1 moles of an ideal gas with a molar heat capacity at constant volume of 5,1 cal/(mol∙K) and a molar heat capacity at constant pressure of 7,7 cal/(mol∙K) starts at 317,6 K and is heated at constant pressure to 335,9 K, then cooled at constant volume to its original temperature. How much heat (cal) flows into the gas during this two-step process? Answer in two decimal places.
