🤓 Based on our data, we think this question is relevant for Professor Ely's class at WVU.
A chemist measures the energy change ΔH during the following reaction:
CH4 (g)+2O2 (g) → CO2 (g) + 2H2O (l) ΔH = -882. kJ
Use the information to answer the following questions.
The reaction is:
Suppose 84.2 g of CH4 react. Will any heat be released or absorbed?
(i) Yes, absorbed.
(ii) Yes, released.
If you said heat will be released or absorbed in the second part of this question, calculate how much heat in kJ will be released or absorbed. Round your answer to 3 significant digits.
