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.
Golden retrievers: loyal and playful family dogs

The priority nursing intervention for this client is FOR THE NURSE TO TAKE CARE OF THE IMPAIRED GAS EXCHANGE.
Dyspnea is a medical condition in which the affected individuals have difficulty in breathing properly, that is, such individuals usually experience shortness of breath. Shortness of breath is one of the symptoms that are associated with heart failure. In the scenario given above, the first thing for the nurse to do is to ensure that the patient is breathing normally again, before setting out to take care of other things.
