Given the following equation: 8 Fe + S8 —> 8 FeS what mass of iron is needed to react with 5.65 mol of sulfur S8
Answers
Answer:
2522g
Explanation:
8Fe + S8 —> 8FeS
From the question,
8moles of Fe required 1mole of S8.
Therefore, Xmol of Fe will require 5.65mol of S8 i.e
Xmol of Fe = 8 x 5.65 = 45.2moles
Now we need to covert 45.2moles to gram. This is illustrated below below:
Molar Mass of Fe = 55.8g/mol
Number of mole of Fe = 45.2moles
Mass of Fe =?
Mass = number of mole x molar Mass
Mass of Fe = 45.2 x 55.8
Mass of Fe = 2522g
Therefore, 2522g of Fe is needed for the reaction.

Answer:
D) Cobalt (III) chloride.
Explanation:
It is an unstable compound in which the cobalt atoms have a formal charge of +3.
It could be stable but at very low temperatures, while at high temperatures it is found as a gas.
I hope this answer helps you.
Cobalt(III) chloride, often known as cobaltic chloride, is an elusive and unstable cobalt and chlorine chemical with the formula CoCl₃. The cobalt atoms in this combination have a formal charge of +3. Here the correct option is D.
Due to its special characteristics, cobalt chloride (CoCl₃) is a chemical substance that is frequently utilized in scientific study. It is a crystalline solid that is pinkish-red and soluble in ethanol and water. Cobalt ions, which are necessary for the growth and development of both plants and animals, can be found in cobalt chloride.
Cobalt(III) chloride, often known as cobaltic chloride, is an elusive and brittle cobalt and chlorine chemical with the formula CoCl₃. The cobalt atoms in this combination have a formal charge of +3.
Thus the correct option is D.
