Define mechanical energy. using the example of the skateboarder on the half-pipe, explain how kinetic and potential energy relate to the mechanical energy at different positions. enter your answer in the space provided.

Kinetic and potential energy relate to the mechanical energy at different positions because, say for example when you are at the top of the half-pipe you have the potential to go down. When you are moving up or down the pipe, it is mechanical because you are moving.

Explanation:

Hope this helps! :)

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

have a great day because if you dont you and i will be sad
