How many neutrons does an atom of
Copper have in its nucleus?

Answers

Answer 1

Answer: answer:34.55
explanation:number of neutrons=mass number-atomic number
the mass number for copper is 63.55 so you do 63.55-29 (29 is the atomic number) and you would get 34.55

Starch and cellulose are both produced by plants, yet one is easily digested by animals and the other is not. Discuss the differences in the structures of these two molecules and how this may impact whether they can be digested.

Answers

Starch andcellulose have the same substance but different structures. They are bothpolysaccharides. The basic unit of a polysaccharide is the glucose. Glucose,which contains carbon, hydrogen, and oxygen, have two forms. The alpha-glucosewith an alcohol group attached to carbon 1 is down and the beta-glucose withthe alcohol group attached to carbon 1 is up. Starch is the alpha-glucose whilecellulose is the beta-glucose. Starches are linked into a straight chain whereasthe cellulose are connected like a pile of stack paper. When the human bodyeats starch, it can digest the starch but not the cellulose because it has noenzyme that can break it down.

Final answer:

Starch is easily digested by humans due to the presence of enzymes breaking its α-glucose bonds, while humans lack the enzymes to break the β-glucose bonds in cellulose, rendering it indigestible but essential as dietary fiber.

Explanation:

Starch and cellulose are both polysaccharides produced by plants. Their structural differences, however, determine how they can be digested by animals. Starch is made up of α-glucose molecules, which are joined together by 1-4 and 1-6 glycosidic bonds, forming a helical structure. The human digestive system has enzymes like amylase that can break these bonds, enabling the digestion of starch.

Which best describes a chain reaction associated with a nuclear reaction? Neutrons released during a fusion reaction cause other nuclei to fuse. Neutrons released during a fission reaction cause other nuclei to split. Helium nuclei released during a fission reaction cause other nuclei to split. Helium nuclei released during a fusion reaction cause other nuclei to fuse.

Answers

The statement that describes a chain reaction brought about by a nuclear reaction is "neutrons released during a fission reaction cause other nuclei to split." This is applicable to fission reactions only wherein atoms split and produce neutrons that also cause further atoms to split, thus creating a chain or series of reactions.

Review the equation below. 2KClO3 mc012-1.jpg 2KCl + 3O2 How many moles of oxygen are produced when 2 mol of potassium chlorate (KClO3) decompose?

Answers

Stoichiometry of the reaction:

2 KClO₃   =   2 KCl + 3 O₂
  ↓ ↓

2 mole KClO₃ ----------> 3 mole O₂
2 mole KClO₃ ----------> ?

KClO₃ = 2 * 3 / 2

KClO₃ = 6 / 2

= 3 moles de KClO₃

hope this helps!

Answer:

the answer is 3

Explanation:

2 mol of potassium chlorate x $(3)/(2)$ = 3

What relationship do you observe between the temperature and density?

Answers

Answer:Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.
