option B
Explanation:
A spontaneous reaction drive favorable when enthalpy is decreasing and the entropy is increasing on the system. If that happens the reaction occurs spontaneously
1AlBr3+ 3K ---> 3KBr + 1Al
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
Yes , CH3OH - this is methanol
