3. I think you also chose the right answer. Assuming that the Hrxn is written as kJ per mol CH4
4. Heat of solution is the enthalpy change associated with dissolving a solute in a solvent. I think the first choice is the right one.
5. I think you chose the right answer.
40 g creo esa es la respuesta
Answer:Calorimetry
Explanation: In this case, an instrument called Calorimeter is used to measure the amount of heat being transferred
Random errors will shift each measurement from its true value by a random amount and in a random direction. These will affect reliability (since they're random) but may not affect the overall accuracy of a result.
