When iron metal reacts with oxygen, the reaction can form Fe2O3. Write a balanced chemical equation for this reaction, and find
I am Lyosha [343]
<h3>Answer:</h3>

Balanced equation: 4Fe + 3O₂ → 2Fe₂O₃

Moles of oxygen gas = 9 moles

<h3>Explanation:</h3>

To answer the question;

  • We first write the balanced equation between iron metal and Oxygen
  • The balanced equation is given as;

4Fe + 3O₂ → 2Fe₂O₃

  • We are given 6 moles of Fe₂O₃

We are required to determine the number of moles of oxygen needed to form 6 moles of Fe₂O₃.

  • From the equation, 3 moles of oxygen gas reacts to produce 2 moles of Fe₂O₃
  • This means, the mole ratio of O₂ to Fe₂O₃ is 3 : 2

Therefore; Moles of O₂ = Moles of Fe₂O₃ × 3/2

Hence, moles of oxygen = 6 moles × 3/2

                                         = 9 moles

Thus, Moles of Oxygen needed is 9 moles

A phase diagram shows phase changes of a substance by illustrating which of the following? A. pressure vs. time B. pressure vs.
ch4aika [34]

D. Pressure vs. temperature

<u>Explanation:</u>

In physical chemistry, this diagram or graph is utilized to predict the conditions like volume, pressure and temperature at which thermodynamic- ally different phases like solid, gases and liquid occur and both states exist at equilibrium.

The simple phase diagrams are the pressure–temperature diagrams of a simple substance like water. In that diagram, x and y axes were correspond to the temperature and pressure. It shows, in the space of pressure and temperature, the equilibrium lines occur between all the 3 phases of water.
