Protons are positively charged, Neutrons are neutral, And Electrons are Negative, so the correct answer is C.
When gas is dissolved in a liquid, more gas dissolves into the liquid. It states that when the pressure of the gas when dissolved in liquid increases, the solubility increases. Thus, the correct option is C.
<h3>What is Pressure?</h3>
Pressure may be defined as the amount of force devoted perpendicular to the surface of an object per unit area. The unit of pressure is Pascal or Pa.
The solubility of any solution is directly proportional to the pressure that is exerted on it at a given time. As the pressure increases, more the solute dissolves into the solvent.
Therefore, the correct option for this question is C.

B. Slower than the gas is the answer
We are given with the mass of Arsine (![AsH_{3}](https://tex.z-dn.net/?f=AsH_%7B3%7D)
The mass of arsine is 15g
there is a relation between moles, mass and molar mass of any compound which is
![moles=\frac{mass}{molarmass}](https://tex.z-dn.net/?f=moles%3D%5Cfrac%7Bmass%7D%7Bmolarmass%7D)
The molar mass of Arsine = atomic mass of As + 3X atomic mass of H
the molar mass of Arsine = 74.92 + 3X 1 = 77.92 g/mol
Let us calculate the moles as
![moles=\frac{15}{77.92}=0.192mol](https://tex.z-dn.net/?f=moles%3D%5Cfrac%7B15%7D%7B77.92%7D%3D0.192mol)
Molarity is defined as number of moles of the solute in 1 liter of solution.
Molarity = Moles of solute (mol) / Volume of the solution (L)
moles of KCl = mass (g) / molar mass (g/mol)
= 10.0 g / 74.5 g/mol
= 0.134 mol
Hence molarity = 0.134 mol / 0.500 L
= 0.268 mol/L
