The Answer would be False.
Water is a polar molecule because of its shape
A weak acid in equilibrium would mean that the solution contains the corresponding ions and the acid molecule that are in equilibrium with each other. A weak acid is an acid that does not dissociate completely into ions. Therefore, the solution would have the HA molecule as well with, H+ and A- ions.<span />
Answer:
A) It tends to increase from top to bottom of a group
Find out how many molecules there are in 2moles
To do this multiply avagadro's constant by 2 (6.02x10^23 * 2)
This gives 1.204x10^24 molecules
For every molecule you have 4 oxygen atoms so do 1.204x10^24 * 4
Answer = 4.816x10^24
