Which of the following are most likely to form a metallic bond?

victus00 [196]

I think the correct answer from the choices listed above is the first option. It would be several gold atoms that will form <span>a metallic bond. It is the most logical choice since it is a metal while the others are nonmetal and a combination of metal and nonmetal. Hope this answers the question. Have a nice day.</span>

Determine the number of grams of carbon dioxide that can be formed from 0.500 grams of iron oxide and an excess of carbon.

Nimfa-mama [501]

Taking into account the reaction stoichiometry, 0.2066 grams of CO₂ are formed from 0.500 grams of iron oxide and an excess of carbon.

<h3>Reaction stoichiometry</h3>

In first place, the balanced reaction is:

2 Fe₂O₃ + 3 C → 4 Fe + 3 CO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Fe₂O₃: 2 moles
C: 3 moles
Fe:4 moles
CO₂: 3 moles

The molar mass of the compounds is:

Fe₂O₃: 159.7 g/mole
C: 12 g/mole
Fe: 55.85 g/mole
CO₂: 44 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Fe₂O₃: 2 moles ×159.7 g/mole= 319.4 grams
C: 3 moles ×12 g/mole= 36 grams
Fe: 4 moles ×55.85 g/mole= 223.4 grams
CO₂: 3 moles ×44 g/mole= 132 grams

<h3>Mass of CO₂ formed</h3>

The following rule of three can be applied: if by reaction stoichiometry 319.4 grams of Fe₂O₃ form 132 grams of CO₂, 0.500 grams of Fe₂O₃ form how much mass of CO₂?

$mass of CO_{2} =\frac{0.500 grams of Fe_{2}O_{3}x132 grams of CO_{2} }{319.4 grams of Fe_{2}O_{3}}$
