<span>H2O, or water, in the form of water vapor, is a very strong greenhouse gas. Water vapor is part of a feedback loop where as the temperature increases, so does the water vapor, basically creating its own system where more water vapor is constantly being applied as a greenhouse gas to the atmosphere by its own evaporation into the atmosphere.</span>
Answer:
If the volume of the container is decreased by a factor of 2 the pressure is is increased by the same factor to 1664 torr.
Explanation:
Here we have Boyle's law which states that, at constant temperature, the volume of a given mass of gas is inversely proportional to its pressure
V ∝ 1/P or V₁·P₁ = V₂·P₂
Where:
V₁ = Initial volume
V₂ = Final volume = V₁/2
P₁ = Initial pressure = 832 torr
P₂ = Final pressure = Required
From V₁·P₁ = V₂·P₂ we have,
P₂ = V₁·P₁/V₂ = V₁·P₁/(V₁/2)
P₂ = 2·V₁·P₁/V₁ = 2·P₁ = 2× 832 torr = 1664 torr
Matter is made of very tiny particles. One mole of a substance contains a given amount of particles. This number is constant for all particles- 6.022×10^23<span> , and is called Avogadro's constant. To get the number of particles in 4g of butane, we need to calculate the number of moles represented by 4 g, then multiply by the Avogadro's constant (Since each mole has particles equivalent to the Avogadro's constant)
Therefore, if 1 mole = 58.1g
how many moles will be equal to 4g?
we cross multiply (4x1) divide by 58.1
equals 0.068847moles
multiply by Avogadro constant = 4.1466 x 10^molecules
But remember the question is not about the number of molecules in butane, its about the number of carbon atoms.
Since there are four carbons in butane, and each has </span> 4.1466 x 10^22 atoms
to get the number of atoms, we multiply by four
equals 1.6586 x 10^atoms
Answer:
hydrogen and oxygen make up water molecules
These are the two phases involved in chromatography. The mobile phase is usually liquid and is the solvent between the two. The solvent can attract some substances that has an affinity to it, thereby separating the polar from the non polar substances. On the other hand, the stationary phase is the media or medium which is a solid substance in which the unknown sample or the solution to be analysed is passed. As the term implies , it is stationary and substances in the unknown sample that has affinity to it or to the reagents in it will not travel along the column, but stay with the stationary medium, thereby allowing a separation of the substances present in the unknown sample/solution.
