The combustion of 45.0 g of methane (natural gas) releases 2498 kj of heat energy. what amount of energy (in kilocalories) would be released for the combustion of 0.440 oz (ounces) of methane?

166.13 kcal

Explanation:

1 ounce = 28.35 g

0.440 ounce=

Given: 45.0 g of methane releases= 2498 kJ of heat energy

Thus 12.47 g of methane releases= of heat energy

1 kJ =0.24 kcal

692.2 kJ=

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.
