So I believe you are supposed to take notes based on the guiding questions (the questions on the side).
Answer:
The correct answer is m= mol solute kg soivent
Explanation:
Molality is a measure of concentration, which indicates the moles of solute (in this case sodium hydroxide) in 1kg of solvent .
In this case:
0,800 kg water-----0,400 mol NaOH
1 ,000 kg water ---x=(1 ,000 kg water x 0,400 mol NaOH)/0,800 kg water
x=0,5 mol NaOH---> <em>The solution is 0,5 molal (0,5 m)</em>
Answer:
Ethyl heptanoate (see the attached image for the structure).
Explanation:
- The reaction of heptanoic acid and ethanol will result ethyl heptanoate ester.
- Ethyl heptanoate is the ester resulting from the condensation of heptanoic acid and ethanol. It is used in the flavor industry because of its odor that is similar to grape.
- Kindly, see the attached image of the structure and the reaction.
Answer:
