now put that into your own words; if you cant, try drawing pictures to help you :) that might help you revise too, but remember to add info underneath, otherwise you might not understand it when you come back to it later
15:15 which cancels to 1:1 so for each mole of co2 u get a mole of carbon monoxide

Answer: option A. to decrease the solubility of the organic product in water
Explanation: sodium chloride solution act as a drying agent to remove water from an organic compound that is in solution. The salt water works to pull the water from the organic layer to the water layer,therby decreasing
If 20. 3 grams of an aqueous solution of iron(ii) chloride contains 2. 71 grams of iron(ii) chloride, then percentage by mass of iron(ii) chloride in the solution is 13.34%
Calculation,
Given:
mass of an aqueous solution of iron(ii) chloride = 20. 3 grams
mass of iron(ii) chloride = 2. 71 grams
The percentage by Mass is equal to percentage of mass of solute present in total mass of solution. It is also known as Mass percentage.
percentage by Mass = 100× 2. 71 grams/20. 3 grams = 13.34%
Hence, the percentage by mass of iron(ii) chloride in the solution is 13.34% .
