So where the "following" at?
A hidden virus hides out inside the host cell for a time before it becomes active. An example of this is a cold sore on your lip.
If you were to compare the mass of the products and reactants in a reaction, you would find that the mass of the products <span>is equal to the mass of the reactants.</span>
The correct option is C.
The density of an object refers to its mass per volume. Water and ice have different densities. The differences in their densities is due to the empty spaces which exist in the structure of ice. Because of the empty spaces, the structure of ice occupy more volume than that of water, hence it is less dense than water.
The answer is ( The concentrations of the products and reactants do not change.)
