Voltalc cells produce a positive overall charge. What does this indicate? OA. The reaction is likely to be endothermic.
OB. The reaction is spontaneous.
OC. The reaction is not likely to occur.
OD. The reaction is not spontaneous.

24. a sports ball is inflated to an internal pressure of 1.85 atm at room temperature (25 °c). if the ball is then played with outside where the temperature is 7.5 °c, what will be the new pressure of the ball? assume the ball does not change in volume nor does any air leak from the ball a) 0.555 atm b) 1.74 atm c) 1.85 atm d) 1.97 atm

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?

The diagram below shows the movement of particles. what does this piece of evidence best support? the collision theory the maxwell-boltzmann distribution the effect of pressure on reaction rates the effect of temperature on reaction rates
