A.
As the density of a substance increases, the attraction among its particles increases.
Explanation:
The relationship between density and particle attraction is that as the density of a substance increases, the attraction among its particles increases.
- Density is the function of the mass and volume of body.
- Mass is the amount of particles a substance contains. It is directly related to the density.
- Volume is the amount of space a substance occupies. It is inversely related to the density.
- A substance will have a large volume if it is poorly packed and the attraction between particles is very weak or low.
- Particles that are well packed have high attraction between their particles. This reduces their volume and the density will increase.

Answer:
Explanation:
.65 M H₂SO₄
H₂SO₄ ⇄ 2H⁺ + SO₄⁻²
C(1-x) 2xC xC
(2xC)². xC /C( 1- x ) = 1.1 x 10⁻²
4 x³C² = 1.1 x 10⁻²
4 . x³ .65² = 1.1 x 10⁻²
x³ = .0065 = 6.5 x 10⁻³
x = 1.867 x 10⁻¹
H⁺ ion concentration =
2xC = 2 x 1.867 x 10⁻¹ x .65
= .2427
pH = - log ( .2427 )
= 0 .615 .
Answer:
In the picture, it's shown that the energy from the sun and carbon dioxide is absorbed by plants through the leaf and is used for cooking food in plants. It is also shown that nutrients and water needed for the plant is absorbed through the roots of the plant. And it's also shown that cooking results in the formation of Glucose and Oxygen in which oxygen is released into the atmospehere and the glucose is stored in the plant for its own needs.
Titanium(III) oxide is a titanium oxide with formula Ti2O3.
Answer:
Carbon dioxide is a gas because the particles surrounding it are more spread out and free from each other. Water is a liquid because the particles are partially spread out and have a medium space to move around. And due to the room temperature, salt's particles can either be hot and move rapidly, or be cold and not move rapidly.
