Answer:
0.33 mol of Fe₂O₃
Explanation:
For the reaction given in the question -
Fe₂O₃ + 5 C + 3O₂ → 2 Fe + 5 CO₂
Balancing the above reaction ,
2Fe₂O₃ + 5 C + 3O₂ → 2 Fe + 5 CO₂
According to the above balanced reaction ,
<u>2 mol of Fe₂O₃ will react with 5 mol of C and 3 mol of O₂ to give 2 mol of Fe and 5 mol of CO₂ .</u>
Hence ,
2 mol of Fe₂O₃ will react with 3 mol of O₂
or ,
3 mol of O₂ ------ 2 mol of Fe₂O₃
Using unitary method ,
1 mol of O₂ ------ 2 / 3 mol of Fe₂O₃
From the question , for 0.49 mol of O₂ ,
0.49 mol of O₂ ------- 2 / 3 * 0.49 mol of Fe₂O₃ = 0.33 mol of Fe₂O₃
There are many forms of energy: like solar, wind, wave and thermal to name a few, but the 6 Forms of Energy we study in Needham are: Sound, Chemical, Radiant, Electric, Atomic and Mechanical. Sound Energy- is produced when an object is made to vibrate. Sound energy travels out as waves in all directions.
Answer:
Yes
2Ag + Cu(No3)2 -----(heat) ----- Cu + 2Agno3
When heat energy is passed through Cu(No3)2 then the reverse reaction will occur
