Use n1/V1 = n2/V2

.1/2 = .4/V2
.1V2 = .8
V2 = 8 L or D

Answer:The new volume when 0.40 moles of gas are added to the balloon is 8 L.

Explanation:

Initial moles of gas n_1 = 0.10 moles

initial volume of the balloon, V_1 = 2.0 L

Final moles of gas n_2 = 0.40 moles

Final volume of the balloon, V_2 = 2.0 L

Avogadro Law:\frac{n_1}{V_1}=\frac{n_2}{V_2}

V_2=\frac{n_2\times V_1}{n_1}=\frac{0.40 mol\times 2.0L}{0.10 mol}=8.0 L

The new volume when 0.40 moles of gas are added to the balloon is 8 L.

o-na [289]

Kilauea volcano in Hawaii emits 200-300 tons of sulfur dioxide into the atmosphere each day. This is an example of

  • the impact of natural processes on the earth's environment.
  • air pollution from a natural source.
  • the magnitude of the chemistry associated with the environment.

Kilauea volcano in Hawaii emits noxious compounds of sulfur dioxide and other harmful pollutants as a result of a reaction with atmospheric water vapors and oxygen.

This reaction results in acid rain and volcanic smog which pollutes the air.

Over the years, the volcano has become a potential threat to health as harmful oxides are accelerating respiratory problems and acid rain destroys crops, and also harms water supplies.

Calculate the atomic mass of silicon. The three silicon isotopes have atomic masses and relative abundances of 27.9769 amu (92.2
Kamila [148]
The atomic mass would be 28.08535 amu. Multiply 27.9769 by .92297 = 25.803. Multiply 28.9765 by .046832 to get 1.357. Multiply 29.9738 by .03872 to get .925351136. Add 25.803 + 1.357 + .03872 to get 28.08535 amu
