Answer: C) Is gold heavier than silver?
Explanation: .-.
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.
Cell division occurs in the final stage of mitosis called telophase. in this stage, the cell prepares for cytokenisis, in which the cell is split.
Coyote population change due to change occur in the climate.
<h3>How coyote population changed?</h3>
The modern Northeast (Maryland) coyote population changed from the historic (North Dakota) population over the past 70 years due to climate change as well as change that occurs in their genes. Climate change is the major factor that is responsible for change in coyote population.
So we can conclude that coyote population change due to change occur in the climate.
