1. PbO is a possible formula units, since O has charge of 2- and Pb can have a charge of 2+ or 4+, if it uses the 2+ ion, the charges will balance out to form PbO. Li+ and B(3-) would have Li3B, Al(3+) and Pb(2+) are both positive charges and would not balance out, Cl- and O(2-) are both negative charges and would not balance out.
2. Iodine is a halogen, so it has a charge of -1. Calcium is an alkaline earth metal in Group 2, so it has a charge of 2+. Therefore, if they were to form a formula unit, the resultant would be CaI2 (2 iodine atoms of 1- charge are needed to balance out the 2+ charge on the calcium atom).
3. Strontium is an alkaline earth metal with a charge of 2+, while phosphorus has a charge of 3-. Therefore, to balance the charges out, we would need 3 atoms of strontium and 2 atoms of phosphorus. This would give the formula unit of Sr3P2.
The osmotic potential of the solution is less than that of the cell, causing loss of water and shrinkage. This describes a hypotonic solution.
Explanation:
A hypotonic answer is any answer that contains a lower pressure than another answer. Within the biological fields, this usually refers to that has less matter and additional water than another solution.

<span>a cost of fossil fuel energy vs. wind power is that fossil fuels are non-renewable resources (it takes millions of years to form them) compared to wind power which is renewable (there's pretty much a non-stop flow of wind).
another cost of fossil fuel energy is that CO2 is a byproduct of it's use and what it takes to GET the fossil fuel. a huge increase in CO2 is thought to be bad for the environment as well.
one benefit of fossil fuel: they can be burned and produce great amounts of energy that we can harness (use).</span>
