Answer:
See explanation
Explanation:
Iron exhibits two stable oxidation states, +2 and +3 states. The difference between FeO and Fe2O3 is that, in FeO, Fe is in the +2 oxidation state while in Fe2O3, Fe is in the +3 oxidation state
In FeO, iron looses two electrons which are gained by oxygen as follows;
Fe^2+ + O^2- -----> FeO
In Fe2O3, Fe looses six electrons while oxygen has gained six electrons as shown;
2Fe^3+ + 3O^2- ------>Fe2O3
Answer:
17.2 moles of Iron are required
Explanation:
Based on the chemical reaction:
2Fe + 3S → Fe₂S₃
<em>2 moles of Fe react with 3 moles of S to produce 1 mole of Iron (III) sulfide</em>
<em />
Assuming and excess of sulfur, if we want to obtain 8.6 moles of Fe₂S₃ are required:
8.6 moles Fe₂S₃ * (2 moles Fe / 1mol Fe₂S₃) =
<h3>17.2 moles of Iron are required</h3>
That if we don’t separate our selves hundreds and thousands of people will die but if we stay apart it will resolve sooner
For the first question, its revise the hypothesis and develop a new experiment to test it
For the second question, the fertilizer independent variable
