The ozone layer protects humans from harmful UV rays, because it acts as a sort of filter for any toxic or overpowering waves from damaging our skin. This goes for animals, as well.
Answer: The mole to mole ratio are the stoichiometric factors of the chemicals in your balanced reactions and are always in whole numbers. When we balance a chemical reaction, whole numbers are always used for easy convention.
Explanation:
Correct Answer: option B. moderately polar covalent
Reason:
Both phosphorus and oxygen are non-metals, and hence they are bonded by covalent bonds. Furthermore, the electro negativity of P and O is 2.1 and 3.5 respectively. The difference in electro negativity is 1.4. Due to the difference in electro negativity, nature of the P-O bond in phosphorus pentoxide (P2O5) is moderately polar covalent.
Its an x if u r trying 2 solve an equation
Answer:
3L
Explanation:
The following data were obtained from the question:
V1 (original volume) = 6L
P1 (original pressure) = 1.5 atm
P2 (new pressure) = 2 x P1 ( since the new pressure is doubled)
P2 = 2 x 1.5
P2 = 3 atm
V2 (new volume) =?
Using the Boyle's law equation P1V1 = P2V2, the new volume can be obtain as follow:
P1V1 = P2V2
1.5 x 6 = 3 x V2
Divide both side by 3
V2 = (1.5 x 6)/3
V2 = 3L
From our calculations, the new volume will be half the original volume and this will be 3L
