I believe 11 is B 12 is C 13 is B and 14 is C
Answer:
25 mol.
Explanation:
The balanced chemical equation for the reaction depicted in this question is as follows:
4Fe + 3O2 → 2Fe2O3
Based on the above balanced equation, 4 moles of Fe produced 2 moles of Fe2O3.
Hence, 50 moles of Fe will produce as follows:
50 mol Fe × 2 mol Fe2O3/4 mol Fe
= 100/4
= 25 mol of Fe2O3

Cations with (+ ) charges lose electrons in order to obtain an octet (8 valence electrons) when they ionically bond with another ion. We're looking for the ions that loses electrons here. So, from the table:
Al 3+ , S 2- , O 2-, Ag + , Ne ( noble gas, no charge)
Since Al and Ag has (+) charges, they are going to lose electrons to form ionic bonds with other atoms.
Carbon monoxide, nitrogen oxides, and hydrocarbons
Carbon monoxide, CO, is a <em>poisonous gas</em>.
Nitrogen oxides (e.g. NO and NO_2) cause <em>smog and acid rain</em>.
Hydrocarbons (general formula C_xH_y) cause <em>smog</em>.
