Answer is: A. be digested and absorbed quickly.

Starch (carbohydrate) is a polymeric carbohydrate consisting of a large number of glucose units bonded by glycosidic bond.

Starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.  

Food rich in carbohydrates has high energy content, because human body can digest it very fast.

Some fruits have a lot of cellulose (also carbohydrate) and fiber, so human body cannot digest it or digest it very slowly.

A because if it was high in fiber it would go slowly that's why people eat allot of fiber a day before a race or workout

Consider the reaction.
N76 [4]

Answer: m = 50 g ZnSO4

Explanation: First is convert the moles of Zn to the moles of ZnSO4 by having their mole ratio which is 2:2 based from the balanced equation. Next is convert the moles of ZnSO4 to mass using its molar mass.

0.311 mole Zn x 2 moles ZnSO4 / 2 moles Zn

= 0.311 moles ZnSO4

0.311 moles ZnSO4 x 161 g ZnSO4 / 1 mole ZnSO4

= 50 ZnSO4

A lithium atom has three protons, three neutrons, and three electrons. what is the overall charge on this atom? a–3 b 0 c 1 d 3
fredd [130]

  Lithium atomic number = 3

  Li atom has 3 protons,3 electrons.Then it has no charge.

So the charge of Li atom here is zero.

<u>Option b: 0 is the right answer.</u>

I need the answers to all three questions pls:
Klio2033 [76]

Answer:

Explanation:

8) As a sulfur atom gains electrons, its radius

A) decreases

B) increases

C) remains the same

Answer:

Increases

Explanation:

when an atom form ion its atomic radius changed from neutral atomic radius.

if the atom form cation its atomic radius is smaller than neutral atomic radius.

If atom form anion its anionic radius is larger than the neutral atomic radius.

The reason is that when electron is remove energy shell deduced so cation get smaller ionic radii while in case of anion electron is added and size increase.

when sulfur gain electrons it form anion that's why its radius increases.

9) Which element forms an ion larger than its atom?

A) Na B) Ne C) Ba D) Br

Answer;

Br

Explanation:

when an atom form ion its atomic radius changed from neutral atomic radius.

if the atom form cation its atomic radius is smaller than neutral atomic radius.

If atom form anion its anionic radius is larger than the neutral atomic radius.

The reason is that when electron is remove energy shell deduced so cation get smaller ionic radii while in case of anion electron is added and size increase.

In given list of elements sodium and barium form cation while bromine form anion.

That's why anion of bromine is larger than atom.

while neon is inert it cannot form ion.

10. Which of the following particles has the smallest

radius?

A) Na B) K° C) Na+ D) K+

Answer:

Na⁺

Explanation:

Atomic radii trend along group:

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased .

Sodium and potassium are present in group one. Sodium is present in period three while potassium is present in period four. So atomic size of sodium is smaller and when it form the cation its cation is smaller than its atom because of losing of electron.The reason is that when electron is remove energy shell deduced so cation get smaller ionic radii
