Answer:
A. It is stable
Explanation:
Ed22
Stability is the property that would xenon most likely to have. Therefore, the correct option is option A.
What is xenon?Chemically speaking, xenon is a gas with the atomic number 54 and the symbol Xe. It is a thick, colourless, and odourless noble gas that is present in minute levels in Earth's atmosphere. It may go through a few chemical reactions, such as the creation of xenon hexafluoroplatinate, which is the initial noble gas combination to be created, despite typically being unreactive.
Flash lamps, arc lamps, and general anaesthetics all employ xenon. The early laser designs utilised xenon flash lamps for pumps and a xenon monomer molecule (Xe2) for the lasing medium in the initial excimer laser design. Stability is the property that would xenon most likely to have.
Therefore, the correct option is option A.

Chemical equilibrium is a dynamic equilibrium that is affected by changes in temperature, concentration and pressure
What is chemical equilibrium?Chemical equilibrium is a dynamic state in a chemical reaction in which the rate of forward reaction is equal to the rate of backward reaction.
For a reaction in equilibrium, the following factors affect equilibrium:
temperature pressure concentrationThe principle of chemical equilibrium states that in an isolated system in equilibrium, equilibrium will shift to annul any constraint applied in the system.
Therefore, chemical equilibrium is dynamic and is affected by temperature, concentration and pressure.

Determine the pressure change when a constant volume of gas at 0.850 atm is heated from 20.0C to 30.0C
Answer:
0.425 atm
Explanation:
According to Ideal Gas Equation,
PV = nRTTherefore, P ∝ TP₁T₂ = P₂T₁Given :
P₁ = 0.850 atmT₁ = 20.0 CT₂ = 30.0 CSolving :
0.85 x 30 = P₂ x 2030 x 17/20 = P₂ x 20510 = 400P₂P₂ = 510/400 = 1.275 atmChange in pressure = ΔP = P₂ - P₁ = 1.275 - 0.850 = 0.425 atmThe Henry's law constant for H2 is 8.1×10−4 Matm at 25∘C. What pressure of hydrogen is needed to maintain a H2 concentration of 0.42 M?
The pressure of hydrogen needed to maintain a H₂ concentration of 0.42 M is 518.5 atm
Henry's lawThis states that the solubility / concentration of a gas in liquids at constant temperature is proportional to its pressure. Mathematically, it can be expressed as
S = KP

For a gaseous reaction, N2 + 3H2 gives 2NH3. If 20 ml of nitrogen completely reacts with hydrogen, then what is the volume of produced NH3?
N2(g) + 3H2(g) → 2NH3(g)
20ml of nitrogen
to find:the volume of produced NH3
solution:So, 1 volume of nitrogen gas reacts with 3 volumes of hydrogen gas to produce 2 volumes of ammonia gas.
For this gaseous reaction in which all the reactants and products are gases we could write a chemical equation:
1 volume N2(g) + 3 volumes H2(g) → 2 volumes NH3(g)
1 volume of N2 is 20 ml so 2 volume of NH3 will be 40 ml .
Then , 20 ml N2 will give 40 ml of NH3
= 40 ml

What is the molarity of a methanol solution produced when 0.2 L of a 3 M solution was diluted to 0.8 L?
A-0.2M
B- 0.4M
C-0.75M
D-0.8M
The molarity of the methanol solution produced at the given number of moles and volume is 0.75 M.
Molarity of the methanolThe molarity of the methanol is determined from the ratio of the number of moles of the methanol to the volume of the methanol.
The molarity of the methanol is calculated as follows;
Molarity = moles/volume
moles = 0.2 L x 3 M = 0.6 mole
Molarity = 0.6 mol/0.8 L
Molarity = 0.75 M
Thus, the molarity of the methanol solution produced at the given number of moles and volume is 0.75 M.
