Answer:
B
Explanation:
And, water is called the "universal solvent" because it dissolves more substances than any other liquid. This allows the water molecule to become attracted to many other different types of molecules.
Answer:
23.9g of Fe₂O₃ are produced
Explanation:
<em>Are formed when 16.7g of Fe reacts completely...</em>
<em />
Based on the reaction:
4Fe + O₃ → 2Fe₂O₃
<em>4 moles of Iron react per 1 mole of O₃ producing 2 moles of Fe₂O₃.</em>
<em />
To solve this question we need to convert the mass of iron to moles. The ratio of reaction is 2:1 -That is, 2 moles of Fe produce 1 mole of Fe₂O₃-. Thus, we can find the moles of Fe₂O₃ produced and its mass:
<em>Moles Fe -Molar mass: 55.845g/mol-:</em>
16.7g Fe * (1mol / 55.845g) = 0.299 moles of Fe
<em>Moles Fe₂O₃:</em>
0.299 moles Fe * (2 mol Fe₂O₃ / 4 mol Fe) = 0.150 moles Fe₂O₃
<em>Mass Fe₂O₃ -Molar mass 159.69g/mol-:</em>
0.150 moles Fe₂O₃ * (159.69g / mol) =
<h3>23.9g of Fe₂O₃ are produced</h3>
