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.
Answer:
I think this is false. Bacteria grow best in an environment that is neutral or slightly acidic.
Answer:
1.I predict that plants and animals would get sick, die, and lose their homes, while us humans would get sick and we would live in filth.
2.E-waste is a growing problem because as the want for electronical devices grows, people get rid of their new ones in the wrong ways when they could be recycling the parts and contribute to the worlds waste a lot. One was of mitigating this problem is to encourage people to recycle their e-waste.
3.Three things local govermants can do to encourage more primary and secondary waste prevention are setting stricter laws on waste disposal, encourage locals to recycle, and put stricter waste control on factories and businesses.
