Simple carbohydrates, also referred to as sugars, include monosaccharides and disaccharides. Monosaccharides consist of a single

sugar molecule, and disaccharides consist of two molecules of sugar joined together. Complex carbohydrates are larger molecules with many sugar molecules. Choose the correct statement about simple or complex carbohydrates. a) Lactose is a five-carbon monosaccharide found in ribonucleic acid (RNA). b) Sucrose is composed of one glucose molecule and one maltose molecule. c) Glucose, fructose, and galactose each contain 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. d) Carbohydrates contain carbon, hydrogen, and nitrogen. e) Oligosaccharides and polysaccharides are classified as simple carbohydrates.

Answer:

C is correct

Explanation:

A is wrong.

Lactose is a double sugar or disaccharide.

B. is wrong.

Sucrose is a double sugar as well as maltose . A double sugar is expected to contain 2 simple sugars. Sucrose contain glucose and fructose. Maltose itself is a double sugar.

C.is right

The three are simple sugar and they contain the exact atoms and numbers. In fact they are all isomers and essentially would have the same molecular formula. While glucose and fructose are functional group isomers, glucose and galactose are diastereoisomers.

D. is wrong.

Carbohydrates do not contain nitrogen

E. is wrong.

They are not simple carbohydrates but are polymers.

Ber [7]

Answer:

H₂Se

Explanation:

A way of estimating the acidity of a weak acid is by analizing the<em> stability of the formed anion</em>. In this case, we should find a Group 6A element that in its anionic forms (HX⁻ and X⁻²) is more stable than HS⁻ and S⁻², thus it would be more acidic in aqueous solution.

The anionic forms of Se are more stable than the forms of S, similarly to how Br⁻ is more stable than Cl⁻.

Matt needs a suggestion to test the nature of solution besides it's taste and corrosiveness. What suggestion would you recommend
grandymaker [24]

A solution with pH less than 7 is acidic while that with a pH greater than 7 is alkaline. So, in order to test the nature of solution( whether acidic or basic) we would use a litmus paper. Litmus paper contains a pH sensitive dye which is red colored in acidic form and blue colored in basic form. Acidic solution turns blue litmus paper red. Alkaline solutions turn red litmus paper blue. Hence, the nature of solution can be detected by using litmus paper test.
