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.

Hitman42 [59]

Scientists are studying compounds in a newly discovered rainforest plant. The plant produces an unusual substance that local people say acts as an anesthetic. If another scientist tests the substance using iodine, the scientist testing for carbohydrates.

The existence of carbohydrates in leaves can be sampled by the Iodine test. When chlorophyll is removed from the leaf by boiling it in alcohol and then placing two drops of iodine solution it turns blue in color which indicates the presence of starch.

The iodine test is a test that is utilized to test for the existence of starch. The mixture of starch and iodine produces an extremely blue-black color.

Explain why scientirsts concluded that the instructions for species characteristics were carried in DNA.
siniylev [52]

Answer:

Explanation:

Deoxyribonucleic acid is said to contain instruction for species characteristics because it carries the information that characterize an individual.

DNA are made up of Nitrogenous bases that are unique codes specify by an individual and no two person has the same the DNA.

Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains gene which helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.
