Answer: iron (iii) oxide, Fe2O3.
Explanation: we must calculate the oxidation state of Fe in Fe2O3
Fe2O3 = 0
2Fe + 3(-2) = 0
2Fe — 6 = 0
2Fe = 6
Fe = 6 /2 = 3
So the oxidation state of Fe in Fe2O3 is +3
So the name of the compound is iron (iii) oxide
Ik it's not magnesium because that was my first answer. The correct answer would be Sulfur. Sulfur is a non metal. All the other answers are good conductors of heat
10% solution means=
=
= 100 mg/mL
If the dentist inject 0.3 mL, that is equal to 0.3× 100 mg.
If the dentist inject 0.3 mL, that is equal to 30 mg.
So, as anesthetic procaine hydrochloride is often used to deaden pain during dental surgery. the compound is packaged as a 10.% solution (by mass; d = 1.0 g/ml) in water. When our dentist
injects 0.30 ml of the solution, 30 mg of procaine hydrochloride (in milligrams) is injected.
