1 )Which of the following is a possible formula unit? PbO Li2B Al2Pb3 ClO
Nataly_w [17]
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 rapid depolarization phase of the action potentials of myocardial contractile cells is due primarily to which ion(s)?
Lyrx [107]

The rapid depolarization phase of myocardial contractile cells is due to the Na+ ions. Sodium ions are essential for regulation of blood and body fluids, communication of nerve impulses, heart activity, and metabolic purposes. Physiologically, it survives as an ion in the body. Sodium is needed by animals but is not needed by plants. The human prerequisite for sodium<span> must be less than 500 mg per day. </span>
