Answer is 
.
Explanation: To calculate the mass of 1 Xe-atom , we will require atomic mass of Xe which is 131.29amu.
This atomic mass is the mass of 1 mole of 1 Xe-atom. One mole of Xe-atom is 
atoms of Xe. We will use this relation to convert Mass of Xe-atom into grams.
=
Temperature and Pressure One way to increase the solubility of a gas is to decrease the temperature of the liquid. The solubility of a gas in a liquid is usually temperature dependent, although it depends on the particular combination of which gas and which liquid. Usually the solubility of a gas goes down with increasing temperature (think of warm carbonated beverages going flat).
<span>The other way to increase the solubility is to increase the pressure of the gas. The higher the pressure of the gas above the liquid, the more will dissolve. Again, think of a carbonated beverage: when it is sealed it doesn't go flat because it is under pressure, but when open to air, it will go flat. </span>
it should be True unless if I’m wrong
Answer:
false
Explanation:
Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced.
Answer is: Increased pressure would increase the rate of forming water vapor.
According to Le Chatelier's Principle, the position of equilibrium moves to counteract the change, the position of equilibrium will move so that the concentration of products (water waper) of chemical reaction increase, if:
1) decrease temperature, because this is exothermic reaction (ΔH is negative).
2) increase concentration of reactants (oxygen and hydrogen).
3) increase pressure of the system, so reaction moves to direction where is less molecules.
