Answer:
A monosaccharide that contains 4 carbon atoms, one of which is in an aldehyde group, is classified as an aldotetrose.
Explanation:
A tetrose is a monosaccharide with 4 carbon atoms.
They have either an aldehyde functional group in position 1 (aldotetroses).
or a ketone functional group in position 2 (ketotetroses).
So, A monosaccharide that contains 4 carbon atoms, one of which is in an aldehyde group, is classified as an aldotetrose.
Explanation:
Ions are the species that contain a charge either positive or negative charge.
When a neutral atom loses an electron then it acquires a positive charge. Whereas if a neutral atom gains an electron then it acquires a negative charge.
For example, 
means there is +1 charge on sodium.
But if a compound does not contain any charge then it means the compound is neutral.
For example, in the compound 
there is no charge so, this compound is neutral.
Hence, we can conclude that no ions are present in a sample of .
The solution would be like this for this specific problem:
Moles of carbon = 58.8 / 12 = 4.9
Moles of hydrogen = 9.8 / 1 = 9.8
Moles of oxugen = 31.4 / 16 m= 1.96
Ratio 4.9 / 1.96 = 2.5 9.8 / 1.96 = 5.0 1.96 / 1.96 = 1
Simplest formula = C5H10
I hope this helps and if you have any further questions, please don’t hesitate to ask again.
