The substance that the molecules have the strongest attractions to one another is the sugar, a solid. The answer is letter A. The solid has a more definite shape and volume. The particles are locked into place. It cannot be further compressed due to the bond that exists between the molecules. The kinetic energy of the molecules is close to none because the molecules are so close and so compact with each other.
Answer:
a
Explanation:
B. stomach
C. small intestine
D. large intestine
Answer:
The correct answer is A).Liver
Explanation: The liver receives digested food components and stores the glucose to be released into the bloodstream for future use, NOT the small intestine or large intestine
I AM 100% CONFIDENT WITH THIS ANSWER TRUST ME!!!
I know it is NOT small intestine, so Large Intestine.
Answer: H₂SO₄ is the chemical formula that represents sulfuric acid.
Explanation:
1) H stands for hydrogen and H₂ means that each unit contains two atoms of hydrogen.
2) S stands for sulfur. Since there is not subscript, means each unit contains one atom of sulfur.
3) O stands for oxygen, and O₄ means that each unit has four oxygen atoms.
4) The way the compound is build up is the S atom at the center with two double bonds to each to one atom of O, and two single bonds one to each OH ion.
5) Sulfuric acid is a strong acid, so it dissociates in water and alghough the formula H₂SO₄ is used to represent it, the aqueous solution is formed by ions: HSO₃⁻, H⁺, SO₄²⁻, and OH⁻, as represented by these dissociation equaitons show:
1) H₂SO₄ ⇄H⁺ + HSO₄⁻ first dissociation
2) HSO₄⁻ ⇄ H⁺ + SO₄²⁻ second dissociation
So, H₂SO₄ is one form to represent sulfuric acid.
In an aqueous solution, H₂SO₄ represents sulfuric acid.
In an aqueous solution, H₂SO₄ represents sulfuric acid. Sulfuric acid is a strong diprotic acid that ionizes in two stages. The first stage is essentially complete in an aqueous solution, while the secondary ionization is less complete, resulting in the formation of HSO₄⁻, which is a moderately strong acid.

b. Helium
d. Oxygen
Answer: 154.09 g
Explanation:
3 Mg + 2 FeCl3 = 3 MgCl2 + 2 Fe
The mass of MgCl2 produced is calculated:
m MgCl2 = 175 g FeCl3 * (1 mol FeCl3 / 162.2 g) * (3 mol MgCl2 / 2 mol FeCl3) * (95.21 g MgCl2 / 1 mol) = 154.09 g
