The correct option is A.

Reverse osmosis is a special type of filtration, which involves the passing of a solvent through a semi permeable membrane in the direction that is opposite to that of natural osmosis. Pressure is always used in this process to enforce separation. The method is usually used to remove ions, fine dust particles, molecules and larger particles from solvents. The method is especially popular in water treatment and purification.

1. How many moles of CO2 can be produced from a reaction of 10.0 moles CzHg?
mr_godi [17]

Answer:

20 moles of CO2 can be produced from a reaction of 10.0 moles C2H6

Explanation:

In this reaction -

2 moles of C₂H6 produces four molecules of Carbon dioxide (CO2)

So 1 mole of C₂H6 will produce \frac{4}{2} = 2 moles of Carbon dioxide (CO2)

Thus, 10 moles of C₂H6 will produce 2 * 10 = 20 moles of Carbon dioxide (CO2)
