Answer:
3 or more simple sugars combined
Explanation:
A polysaccharid molecules consist of a number of sugar molecules bonded together.
Answer:
C₁₃H₁₈O₂
Explanation:
Empirical formula is the simplest ratio in moles of the elements presents in the compound. Assuming a basis of 100g, we need to convert the mass of each element to moles and, find the ratio of each of these:
<em>Moles C:</em>
75.69g * (1mol / 12.01g) = 6.3 moles of C
<em>Moles H:</em>
8.80g * (1mol / 1.01g) = 8.7 moles of H
<em>Moles O:</em>
15.51g * (1mol / 16g) = 0.97 moles of O
The ratio dividing in the moles of O -Because is the element with the lower amount of moles-:
C = 6.3mol / 0.97mol = 6.5
H = 8.7mol / 0.97mol = 9
O = 0.97mol / 0.97mol = 1
As the ratio must be in whole-numbers, multiplying in 2:
C = 13;
H = 18
O = 2
And empirical formula is:
<h3>C₁₃H₁₈O₂</h3>
Answer:
The answer is below
Explanation:
Ketone is a class of organic compounds which has a carbonyl group such that the carbon atom is covalently bonded to an oxygen atom, while the remaining two bonds are to other carbon atoms or hydrocarbon radicals.
Ketones are highly reactive hydrocarbons, they can be gotten from the oxidization of secondary alcohols. Ketone are used for medicinal applications.
The third option is the ketone
Answer: When a substance is pure, it is composed of one type of molecule. For example, table salt is only composed of (more or less) salt molecules, while seawater has water and salt molecules. A more complicated example of a non - pure substance is soil. It has many different types of nutrients and compounds.
