Answer:
A water molecule can react with the carbonyl group of an aldehyde or a ketone to form a substance known as a carbonyl hydrate, as shown in the first reaction below. The carbonyl hydrates usually form a very small percentage of the molecules in a sample of a specific aldehyde or ketone.
(Nice profile pic also UwU)
Theoretical yield 550 kg - 100%
Actual yield 480 kg - x%
x= 480*100/550 ≈ 87.3 %
Percentage yield ≈ 87.3 %.
In this case, 58.703 has five significant figures because the 3 at the end is significant and therefore makes the 0 significant as well. Since there are 5 significant figures, we need to round off the 7 to get 58.7, which has three significant figures.
Hope this helps.
Explanation:
This indicates that there are more hydroxide ions in solution than there were in the original water. This is because some magnesium hydroxide has dissolved. Calcium hydroxide solution is referred to as "lime water". A liter of pure water will dissolve about 1 gram of calcium hydroxide at room temperature.
