Consider the following intermediate chemical equations. What is the enthalpy of the overall chemical reaction ? -205. 7 kj -113. 4 kj -14. 3 kj 78. 0 kj.

What is the mass defect of a mole of nuclei with 1.8 x 10^15 j/mol binding energy?

Draw the structure for 5-isopropyl-2-methyl-3-nonene

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
