Explanation:

Mg(s) + Cr(C2H3O2)3 (aq)

Overall, balanced molecular equation

Mg(s) + Cr(C2H3O2)3(aq) --> Mg(C2H3O2)3(aq) + Cr(s)

To identify if an element has been reduced or oxidized, the oxidation number is observed in both the reactant and product phase.

An increase in oxidation number denotes that the element has been oxidized.

A decrease in oxidation number denotes that the element has been reduced.

Oxidation number of Mg:

Reactant - 0

Product - +3

Oxidation number of Cr:

Reactant - +3

Product - 0

Note: C2H3O2 is actually acetate ion; CH3COO- The oxidatioon number of C, H and O do not change.

Oxidized : Mg

Reduced : Cr

Which of the following conversion factors would be used to calculate the number of moles of Cl2 produced if 11 moles of HCl were
MissTica

<u>Answer:</u> The moles of chlorine gas produced is 5.5 moles

<u>Explanation:</u>

We are given:

Moles of HCl = 11 moles

For the given chemical reaction:

4HCl+O2\rightarrow 2Cl_2+2H_2O

By Stoichiometry of the reaction:

4 moles of HCl produces 2 moles of chlorine gas

So, 11 moles of HCl will be produced from \frac{2}{4}\times 11=5.5mol of chlorine gas

Hence, the moles of chlorine gas produced is 5.5 moles
