Carbohydrates, more commonly known as sugars, are made up of carbon, oxygen, and hydrogen atoms. the smallest unit of a carbohydrate is a monosaccharide. two monosaccharides make up a disaccharide, and many monosaccharides make up a polysaccharide. disaccharides and polysaccharides can be hydrolyzed back into the individual monosaccharide units. part a select the statement that is incorrect. select the statement that is incorrect. complex sugars are carbohydrates. all carbohydrates have the general formula cn(h2o)n. simple sugars are carbohydrates. carbohydrates contain only carbon, oxygen, and hydrogen atoms. submithintsmy answersgive upreview part part b complete the following sentences about carbohydrates. match the words in the left-hand column with the appropriate blank in the sentences in the right-hand column. disaccharide polysaccharide carbohydrate monosaccharide 1. a carbohydrate that yields many monosaccharides when hydrolyzed is a . 2. a simple sugar is composed of equal parts carbon and water, which gave rise to the general name of any sugar as a . 3. lactose, the sugar in milk, is a , because it can be split into two monosaccharides. 4. a cannot be hydrolyzed any further.

PART A.

The false statement is All carbohydrates have the general formula Cn(H2O)n.

PART B.

1. A carbohydrate that yields many monosaccharides when hydrolyzed is a polysaccharide.

2. A simple sugar is composed of equal parts carbon and water, which gave rise to the general name of any sugar as a carbohydrate.

3. Lactose, the sugar in milk, is a disaccharide , because it can be split into two monosaccharides.

4. A monosaccharide cannot be hydrolyzed any further

Explanation:

The general formula Cn(H2O)n is only for monosaccharides, not for all the carbohydrates.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
