Based on Avogadro's principle, the coefficients in chemical equations involving only gases

represent two types of quantities. Name the two quantities.

Explanation:

Molar ratio is the quantity which will correctly convert between two different substances.

Option B

Explanation:

Molar ratio is used to determine the number of moles of reactants required to convert to desired number of moles of the products and vice versa. As moles are the coefficient written in any chemical equation. The ratio of the number of moles of the reactants to the number of moles of the products will help to determine the molar ratio.

This molar ratio is used as the conversion factor to determine number of moles required in the reactant side for the reactants to form a desired product of desired moles. We can also determine the number of moles utilized from the reactants from the moles obtained in the products using this molar ratio conversion factor.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
