C
Explanation:
the rain does help the soli it can make bacteria
A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
the refractive index of the liquid is 1.476
The refractive index, which has no dimensions, measures how quickly light passes through a substance.
It can also be described as the difference between the speed of light in a vacuum and a medium.
Refractive index is equal to the product of the light's liquid and vacuum speeds.
Therefore.
speed of light in vacuum = 4.96 km/t
speed of light in liquid = 3.36 km/t
Refractive index = 4.96/3.36
Refractive index =1.476
Therefore, the refractive index of the liquid is 1.476

Data:
n (number of mols) = ?
V (volume) = 2.50 Liters
If:
1 L → 1000 g
2.50 L → y
y = 1000*2.50 = 2500 g
Therefore:
m (mass) = 2500 g
Now:
Molar Mass (MM) of oxygen = 16 g/mol
Formula:
Solving:
