The hypothesis should be; "Increasing the amount of ice increases the rate at which the ice will melt"
<h3>What is a hypothesis?</h3>
The term hypothesis refers to a tentative explanation that could be applied in order to explain an observation. When we give a hypothesis, it must be subjected to rigorous experimentation thus it can be confirmed or repelled by experiment.
Now, we can see that the question here is; "How does the amount of salt added to ice affect the rate at which the ice will melt?" This implies that the correct hypothesis here ought to have to do with the impact of the amount of ice in the affirmative.
Thus, the hypothesis should be; "Increasing the amount of ice increases the rate at which the ice will melt"

Answer:
No of neutrons and protons decides mass of the atom. Electrons having negligible
mass are ignored.
Mass of atom
Mass of atom= sum of no of protons(Z) and neutons(N)
=Z+N
For eg:
In hydrogen atom,
Mass of H= Z+N
=1+0
=1 AMU
The answer is [Pb^2+][Cl-]^2
