Momentum = mass × velocity
P = mv
P = 0.08 × 14
= 1.12 kgms^-1

Answer:
A. Endothermic reaction.
B. +150KJ.
C. 250KJ.
Explanation:
A. The graph represents endothermic reaction because the heat of the product is higher than the heat of the reactant.
B. Determination of the enthalpy change, ΔH for the reaction. This can be obtained as follow:
Heat of reactant (Hr) = 50KJ
Heat of product (Hp) = 200KJ
Enthalphy change (ΔH) =..?
Enthalphy change = Heat of product – Heat of reactant.
ΔH = Hp – Hr
ΔH = 200 – 50
ΔH = +150KJ
Therefore, the enthalphy change for the reaction is +150KJ
C. The activation energy for the reaction is the energy at the peak of the diagram.
From the diagram, the activation energy is 250KJ.
If your body did not digest enough food, you would not have the energy to exercise. Food is like fuel for the body.

When heat is applied, energy is applied. so since the state is a solid, there is no terms of energy being applied. Energy is basically "frozen" water turns to ice due to the object reaching its freezing point.
