Answer:
The percentage yield of water is 66.67%.
Explanation:
Mass of oxygen gas = 100 g
Moles of oxygen gas = 
According to reaction, 1 mole of oxygen gives 2 moles of water, then 3.125 moles of oxygen will give:
Mass of 6.25 moles of water :
6.25 mol × 18 g/mol = 112.5 g
Theoretical yield of water = 112.5 g
Experimental yield of water = 75 g
Percentage yield :
The percentage yield of water is 66.67%.
<span>It generally does not mean that there is double the oxygen, but in this case there is double, because the subscript number tells how many atoms of that element are in a particle. In this case, there are two of the oxygen, hence the DI-oxide verbiage, and one of the carbon. When there is only one, it's MONOxide, to indicate only one atom.</span>
FeCl3 very commonly reacts with phenol groups.
hope this helps!!
Number 2 is the correct answer
Answer:
the electrolysis reaction is a non- spontaneous reaction
Explanation:
Since electrons flow from it, the anode in an electrolytic cell is positive, while the cathode is negative when electrons flow into it. The device functions like a galvanic cell in that direction. In an electrolytic cell, an external voltage is applied and that is what causes a non spontaneous reaction
