When you work with molar mass, you solve for the quantity of ''Moles'' within the substance by converting Mass. The way you can tell the equation is balanced would be by knowing whether the moles were equivalent on both sides or not. Therefore, if they are equal, it is balanced considering you have the same amount of moles on each side of the equation.
Answer:
The average atomic mass of oxygen is 15.999u
Answer:
B
Explanation:
A metathesis reaction is a reaction in which cations and anions change partners.
A general equation for a metathesis is
AX+CY→AY+CX, where A and C are cations, and X and Y are anions.
There are three possible products of a metathesis reaction.
A. an insoluble (solid) precipitate
B. water (from neutralization reaction)
C. an insoluble gas that bubbles out of solution
Metathesis reactions are also called double replacement reactions and double displacement reactions.

Answer: Option (c) is the correct answer.
Explanation:
Momentum is the product of mass and velocity.
Mathematically, p = m × v
where p = momentum
m = mass
v = velocity
It is known that mass can be measured in Kilograms or grams. Whereas velocity is measured in meter per second or centimeter per minute or hour.
On the other hand, unit kilometer is a unit of distance and not mass.
Thus, out of the given options km.m/s is not an appropriate unit for momentum.
