Answer: 4 molL-1
Explanation:
Detailed solution is shown in the image attached. The number of moles of NaCl is first obtained. Since the molarity must be in units of molL-1, the volume is divided by 1000 and the formula stated in the solution is applied and the answer is given to one significant figure.
Answer: acetone is a ketone and not an aldehyde. Therefore it's false
Explanation:
Acetone is of structure CH3-CO-CH3
which makes it a ketone.
Both aldehyde and ketone have a carbonyl group but there is difference between aldehyde and ketone.
Aldehydes have a general formula R-CHO
where R is a methyl group including H atom, and CHO is the functional group.
While
Ketone have the general formula R-CO-Ri
where R and Ri are methyl groups excluding H atom, and CO is the functional group.
Hint: ketones usually end with the suffix "one" as in acetone.
Answer:
Triglycerides are actually fats made from condensation of fatty acids and glycerol, and used in making soap because it readily reacts caustic alkali and precipitates soap molcules while glycerol is the produced alongside
Explanation:
Triglycerides are made when 3 molecules of fatty acids condenses with one molecule of glycerol having 3-sites of OH where the condensation takes place with the COOH functional group in the fatty acids and 3 molecules of water
