Steam reforming of methane ( ) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a flask with of methane gas and of water vapor at . he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be . calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to significant digits.

Aplayer uses a hockey stick to push a puck at a constant velocity across the ice. the weight of the puck is 170 n. the coefficient of friction is 0.0600. with what force must the player push the puck so that his force just equals the frictional force? 28.3 n 0.999 n 0.102 n 0.0104 n

Which statements describe how a machine can make work easier? check all that apply. it can put out more force than the input force by decreasing the distance through which force is applied. it can increase the amount of work performed if the output force is in the same direction as the input force. it can apply a force to an object in a different direction than the force applied to the machine. it can increase the distance through which a force acts by exerting less force than was used on it. it can exert a greater force through a greater distance than the force used on the machine.

Aspring is originally 0.4m. when a 23n force is applied it stretches to a total of 0.7m. how far is the spring been extended? what is the spring constant of the spring?
