1 )Which of the following is a possible formula unit? PbO Li2B Al2Pb3 ClO

1 answer:

4 0

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.

WARRIOR [948]

Answer:

How the gelatin is prepared can affect the result.

Explanation:

To perform this experiment efficiently, you need to prepare the jelly made from fresh fruit and the jelly made from canned fruit equally. That's because if you modify the ways of preparing the gelatins, they will show many differences and you won't be able to tell if this difference was caused only by the nature of the fruits, or by the way of preparation. Therefore, the way the gelatins were prepared can modify the experiment result and leave it imprecise and unreliable.

When one species of an ecosystem is endangered, other species that interact with or depend on it are never negatively impacted d

Brums [2.3K]

The statement above is FALSE.
When a particular specie in an ecosystem is endangered, other species that interact with it will be negatively affected and the ecosystem may be throw out of balance. This is because all the components of the ecosystem depend on one another for survival.
