Answer:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

i think A but if I'm wrong sorry
then if increasing then becoming spread out so letter A
The answer is there are 0.25 moles in 15.5 grams of SiO2. To convert grams to moles you put the amount given over the molar mass of the substance and divide to solve.
Answer:
The answer to your question is 19%
Explanation:
Data
Molar mass = 58
Molar mass calculated = 69
% error = ?
Formula
% error = | calculated - theoretical| / theoretical
Substitution
% error = |69 - 58| / 58 x 100
Simplification
% error = 11/58 x 100
% error = 0.19 x 100
Result
% error = 19
