Answer:
The correct answer is: PCl₃ and PCl₅
Explanation:
Law of multiple proportions, also known as the Dalton's Law, states that the when the two different chemical elements combine in order to form two or more than two chemical compounds, then the ratio of mass of the chemical element that combines with the fixed mass of other chemical element is the ratio of small whole numbers.
Example: PCl₃ and PCl₅
Lead can cause
D.) brain damage
Explanation:
Lead poisoning is a sort of metal poisoning generated by lead in the body. The brain is the most sensitive. Symptoms may comprise abdominal pain, illness, headaches, irritability, thought problems, inability to have children, and tingling in the hands and feet. It causes almost 10% of the intelligent weakness of otherwise unknown cause also can result in behavioral problems. Some of the outcomes are strong. In severe cases, anemia, convulsions, coma, or death may occur.
Atomic mass Ca = 40 a.m.u
1 mole Ca ----------- 40 g
2.5 mols Ca -------- ( mass Ca )
Mass Ca = 2.5 x 40 / 1
Mass Ca = 100 / 1
= 100 g of Ca
