The answer to this item depends entirely to the chemical reaction. If the compound, NH4Cl, is in the left hand side of the reaction, when it is added, the reaction will shift to the left. In the same manner, when the compound is in the right-hand side of the reaction, the reaction will shift to the right.
This happens because initially the reaction is in equilibrium and adding another compound to it will most likely lead to the shifting of the reaction.
Slow down because liquids have less movement than gases
The correct answer is carbon.
The element carbon is found in all the organic constituents in the body of a human that comprises carbohydrates, fats, proteins, and nucleic acids. It is the second most abundant element found in the body of a human being. In supplementation to being a basic building block of the majority of the cellular compositions of the body, carbon is found in the blood as carbonic acid and bicarbonates.
P = m*v
p = momentum
m = mass
v = velocity
p = (37 kg + 18 kg)*(1.2 m/s)
p = (55 kg)*(1.2 m/s)
p = 66 kg-m / s
