Answer: (3) carbon dioxide
Explanation: Solubility of solids and liquids is not affected by pressure as they are highly incompressible. Methanol is liquid, carbon dioxide is a gas, sugar is a solid and sodium nitrate is also a solid.
But solubility of gases is affected by pressure as they are compressible and the solubility is governed by Henry's law, which states that mass of gas dissolved in a given liquid ta constant temperature is directly proportional to the pressure of the gas present in equilibrium with the liquid.
Increase in pressure increases the solubility as increase in pressure would lead to decrease in volume of gas particles and hence more number of particles will be present per unit volume and as a result, the number of particles striking the surface of solution and entering the solution will increase. Thus solubility increases.
Answer:
When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions. Most nonmetals become anions when they make ionic compounds. A neutral chlorine atom has seven electrons in its outermost shell.

<u>Answer:</u>
The common name for the compound H2O is water.
<u>Explanation:</u>
The systemic name of H2O is Dihydrogen monoxide.
the correct answer would be C. All matter is made up of molecule because gas is one matter and solid is one matter and water and ice/liquid and solid is not hard to see, so the correct answer would be C. All matter is made up of molecule.
