Answer:
Single displacement (Substitution)
Explanation:
Due to time constraint, I am only able to help you balance the equation.
BALANCED EQUATION ANSWER:
1 NH3(g) + 3 O2(g) --> 1 NO(g) + 3 H2O
N 1 N 1
H 3 H 1 x 3 = 3
O 2 x 3 = 6 O 2 x 3 = 6
Explanation:
In order to balance it out, the amount of each element must match. To do this, you have to multiply specific elements to match the other. As you can see, Nitrogen was already balanced, but the others were not.

Ek = (1/2)mv^2
m=7kg
v=4m/s
Ek=(1/2)(7kg)(4m^2/s^2) = 14 kg m^2/s^2
