Which ion in each pair has greater charge density? Explain.<br> (c) Na⁻ or Cl⁻
boyakko [2]

Cl⁻ has a greater charge density than Na⁻.

The amount of electric charge that can build up across a unit length, unit area, or unit volume of a conductor is known as charge density. In other words, it shows the amount of charge that is held in a certain field. It determines how the charge is distributed and can be either positive or negative.

We encounter electric charge density when measuring electric fields from different continuous charge distributions including linear, surface, and volume. We must also take charge density into account when analyzing current electricity. We must first comprehend this concept of density in order to comprehend charge density. The definition of density for a thing is its mass per unit volume.

Size and charge density are inversely correlated, meaning that the smaller the size, the higher the charge density. This implies that Cl has a smaller volume and a higher charge density.

A sample of Ne gas has a pressure of 654 mmHg with an unknown volume. The gas has a pressure of 345 mmHg when the volume is 495m
Lemur [1.5K]

Answer:

The initial volume of Ne gas is 261mL

Explanation:

This question can be answered using Ideal Gas Equation;

However, the following are the given parameters

Initial Pressure = 654mmHg

Finial Pressure = 345mmHg

Final Volume = 495mL

Required

Initial Volume?

The question says that Temperature is constant;

This implies that, we'll make use of Boyle's law ideal gas equation which states;

P_1V_1 = P_2V_2

Where P_1 represent the initial pressure

P_2 represent the final pressure

T_1 represent the initial temperature

T_2 represent the final temperature

P_1 = 654mmHg\\P_2 = 345mmHg\\V_2 = 495mL

Substitute these values in the formula above;

654 * V_1 = 345 * 495

654V_1 = 170775

Divide both sides by 654

\frac{654V_1}{654} = \frac{170775}{654}

V_1 = \frac{170775}{654}

V_1 = 261.123853211

V_1 = 261mL (Approximated)

<em>The initial volume of Ne gas is 261mL</em>

What is the oxidation number of chromium in dichromate ion, cr2o72-?
castortr0y [4]
Oxidation number is charge of element in compound. Can be neutral, positive or negative.
Oxygen in dichromate has oxidation number -2, becauce there are seven oxygens, net oxidation number of oxygen is -14.
2·x(oxidation number of Cr) + 7· (-2) = -2   2x= +12
x= +6, oxidation number of one chromium is +6.
