Based on Table I, what is the AH value for the production of 1.00 mole of NO2(g) from its elements at
101.3 kPa and 298 K?
1) +33.2 k) 2) -33.2 kJ 3) +132.8 kJ 4) -132.8 kJ

ANSWER: 33.2 kJ

EXPLANATION: This is the heat required to produce two moles of NO2(g). Therefore, it would only require half the amount, or 33.2 kj, to produce just one mole.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
