A block lies on a smooth inclined plane tilted at an angle of 35 o to the horizontal a) Draw the free body diagram for the block b) Determine the block’s acceleration as its slide down the inclined plane c) If the block started from rest 8.5 m up the incline from its base, determine the block’s speed when it reaches the bottom of the incline d) How long did it take the block to reach the bottom of the inclined plane?

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

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

the answer to this question is 3.
