Which statement correctly describes metallic bonds?

KMnO4 + H2S + HCl KCl + MnCl2 + H2O + S8 Did Cl change oxidation number? Yes, no Did Oxygen change oxidation number? Yes, no Did

valkas [14]

Explanation:

KMnO4 + H2S + HCl --> KCl + MnCl2 + H2O + S8

Did Cl change oxidation number?

The oxidation number of Cl in Reactant side is -1

The oxidation number of Cl in product side is -1

NO

Did Oxygen change oxidation number?

The oxidation number of O in Reactant side is -2

The oxidation number of O in product side is -2

NO

Did H change oxidation number?

The oxidation number of H in Reactant side is 1

The oxidation number of H in product side is 1

NO

Did Mn change oxidation number?

The oxidation number of Mn in Reactant side is +7

The oxidation number of Mn in product side is +2

YES

Did S change oxidation number?

The oxidation number of S in Reactant side is -2

The oxidation number of S in product side is 0

YES

Oxidizing agent (element with decrease in oxidation number) = Mn

Reducing agent (element with Increase in oxidation number) = S

If the following elements were to combine with each other, choose which demonstrate the Law of Multiple Proportion. Select all t

Marysya12 [62]

Answer is: Z:X = 7:1 and Y:X = 11:1.

Law of multiple proportions or Dalton's Law said that the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.
In this example ratios are whole numbers, A:Z = 2.5 : 1 and A:Z = 2.2 : 1 are not whole number ratios.
