2 AnswersBiology2 years agoDetermine the amount of heat (in kJ) associated with the production of 1.38x10^4g of NO2 according the following equation:?
2 NO(g) + O2(g)--> 2NO2(g)
ΔH = −114.6 kJ/mol.
my answer I got was 1.72x10^4kj and it keeps saying it is wrong, what am I doing wrong!. Please help
4 AnswersChemistry2 years agoA gas expands and does PV work on its surroundings equal to 345 J. At the same time, it absorbs 141 J of heat from the surroundings.?
Calculate the change in energy of the gas. Note: PV work means work done by a changing volume against constant pressure.
IT IS NOT -204X10^2. IT SAYS IT IS WRONG. I KEEP GETTING THE SAME ANSWER.
