Answer:
21.9 g C
Explanation:
Fe₂O₃ + 3 C ⇒ 2 Fe + 3 CO
This is your chemical equation.
To find the grams of C required, first convert grams of Fe₂O₃ to moles using the molar mass (159.69 g/mol).
(97.1 g)/(159.69 g/mol) = 0.608 mol Fe₂O₃
Then, use the mole ratio between Fe₂O₃ and C to convert moles of Fe₂O₃ to moles of C. You can find the mole ratio by looking at the chemical equation.
(0.608 mol Fe₂O₃) × (3 mol Fe₂O₃/1 mol Fe₂O₃) = 1.824 mol C
You can then convert moles of C to grams using the molar mass (12.01 g/mol).
(1.824 mol) × (12.01 g/mol) = 21.9 g
Answer: <span>A) can form hydrogen bonds.
Water has a high heat capacity. Water is also a good solvent since many things, mostly polar chemical compound, that can be dissolved using it. Water is definitely polar. Water structure is well known to be like "Mickey mouse", causing it to have a more positive pole at the side with Mickey's ears.
Water has hydrogen bond that was causing it has a high boiling point.</span>
