When an aldose reacts with barfoed's reagent, what type of organic compound forms? what type of chemical is this?

aldonic acid, Barfoed's reagent is copper(II) acetate in acetic acid.

Explanation:

Barfoed's test is the chemical test which is used for the detection of the presence of the monosaccharides.

The aldehyde group of aldose sugar is oxidized to the carboxylic group known as, aldonic acid.

RCHO + 2Cu²⁺ + 2H₂O → RCOOH + Cu₂O↓ + 4H⁺

Barfoed's reagent is copper(II) acetate in acetic acid which on reduces to copper(I) oxide forming a brick-red precipitate.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
