What is the balanced chemical equation for the word equation below?

ladessa [460]

Answer:

4Fe + 3O₂ → 2Fe₂O₃

Explanation:

Fe → ²⁺

O → ²⁻

But Iron III is Fe³⁺

So we have Fe³⁺ and O²⁻, the formula for the oxide must be Fe₂O₃ so the equation can be:

4Fe + 3O₂ → 2Fe₂O₃

A correct statement of Henry's law is: a. The concentration of a gas in solution is inversely proportional to temperature. b. Th

AVprozaik [17]

Answer:

e. None of these.

Explanation:

Hey there!

In this case, since the Henry's law is defined in terms of pressure, henry's constant and pressure, as shown below:

$C=K_H*P$

Whereas C is the concentration, KH the Henry's constant and P the pressure, we infer that the concentration of a gas solution is directly proportional to the pressure, which is not the group choices, therefore, the answer is e. None of these.

Best regards!
