Answer:
            Option-D : <span>Decrease the velocities of the particles, and decrease the space between the particles.

Explanation:
                     The solid state of matter is composed of particles closely packed with a minimum space between them. This closed packing of particles occur due to strong interatomic or intermolecular interactions between particles. Therefore, solids particles have zero translational and rotational motions and only show vibrational motions. So, decrease in velocity and decrease in space between particles is the right answer for making solids.</span>

Determine the oxidation state of Cl in CIO3. A +3 B +7 C 0 D +1 E +5
Crazy boy [7]

Answer:

E.) +5

Explanation:

Oxygen always has -2 oxidation number.

Because there are 3 oxygen atoms present, this means oxygen is contributing a -6 charge (-2 x 3 = -6).

Therefore, since the overall molecule is -1, chlorine must have an oxidation number of +5 to cancel all of the negative charges but 1.

You can also think of the problem like an equation. In this equation, "x" is the oxidation number of chlorine, (-2) is the oxidation number of oxygen, (3) is the number of oxygen atoms present, and the equation is set equal to (-1) because that is the overall charge of the molecule.

x - 2(3) = -1

x - 6 = -1

x = 5

7. A movable piston is allowed to cool from 392°F to 104°F. If the initial volume is 105 mL,
-BARSIC- [3]

Answer:

27.9 mL

Explanation:

To find the new volume, you need to use the Charles' Law equation:

V₁ / T₁ = V₂ / T₂

In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature.

V₁ = 105 mL                     V₂ = ? mL

T₁ = 392 °F                       T₂ = 104 °F

V₁ / T₁ = V₂ / T₂                                            <----- Charles' Law

105 mL / 392 °F = V₂ / 104 °F                     <----- Insert values

0.26785 = V₂ / 104 °F                                 <----- Simplify left side

27.9 = V₂                                                     <----- Multiply both sides by 104
