Draw the Lewis structure for ClO.

Answers

Answer 1

The Lewis Structure for ClO.  is attached in the image.

What is Lewis Structure ?

Lewis structure represents the structure of atoms or molecules with their valence electron.

It is a two-dimensional model that helps us to know, how many bond pairs and a lone pair a molecule contains.

Lewis structure of ClO⁻ is very simple to draw as it has only two atoms(chlorine and oxygen), we have to just represent the valence electron around them and complete their octet.

1. Count total valence electron in ClO-

Total number of the valence electrons in chlorine = 7

Total number of the valence electrons in oxygen = 6

Total number of valence electrons  = 7 + 6 + 1 = 14 valence electrons        

[∴one oxygen atom, one chlorine, and one negative charge that count as a one valence electron]

2. Find the least electronegative atom and placed it at center

Connect outer atoms to central atom with a single bond Cl-O bond

Now count the valence electron in the above structure.

Single bond means two-electron , only one single bond is used.

Hence, only 2 valence electrons are used in the above structure from 14 total valence electrons available for drawing the lewis structure of ClO-.

(14 – 2) = 12

We have left with 12 valence electrons more.

3.   Place remaining valence electrons starting from outer atom first

So, put the valence electron around the chlorine and oxygen.

we put 6 electrons around chlorine and oxygen, as each of them already sharing 2 electrons with the help of a single bond between them.

The structure can be seen in the figure attached.

how do gases exert pressure into a cylindrical container

Answers

Answer: The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure. If a gas is heated up, its particles move around more quickly. They hit the walls of their container harder and more often. This increases the pressure. Sometimes the pressure gets so great that the container bursts.

Answers

The volume of distilled water added to the original solution is closest to 300.0 ml.

What is pH?

The potential of hydrogen is a measure of the acidity or alkalinity of a solution equal to the common logarithm of the reciprocal of the concentration of hydrogen ions in moles per cubic decimetre of solution.

Concentration of 30.0 ml sample of [tex]HNO_3[/tex] solution is = 6.31 X [tex]10^{-5}[/tex] M

pH of diluted [tex]HNO_3[/tex] solution = 5.20

We know that,

[tex]pH= -Log [H^+][/tex]

[tex]5.20= -Log [H^+][/tex]

Hence, concentration of unknown diluted [tex]HNO_3[/tex] solution is 6.31 X [tex]10^{-5}[/tex] M.

By the use of the equation:

[tex]HNO_3[/tex] Concentration = [tex]HNO_3[/tex] diluted

[tex]V_{dil} = \frac{(C_conc X V_conc)}{(C_{dil})}[/tex]

[tex]V_{dil}[/tex] = (6.31 X [tex]10^{-5}[/tex] M X 30.0 ml) ÷ (6.31 X 10^{-6} M)

A piece of copper wire that is 180 cm long is 1800 mm long in millimeters. 45 segments of 40mm long can be cut from 1800 mm length of wire.

How to convert cm to mm?

Centimeters and millimeters are both interconvertible units to measure length. The conversion factor is as follows:

1 centimetre = 10 millimetres

This means that if a copper wire is 180cm long, the wire would be;

Answers

Considering the ideal gas law and the definition of molar mass, the molar mass of the sample of gas is 9.17 [tex]\frac{g}{mol}[/tex].

Ideal gas law

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:

P×V = n×R×T

where:

P is the gas pressure.V is the volume that occupies.T is its temperature.R is the ideal gas constant. The universal constant of ideal gases R has the same value for all gaseous substances.n is the number of moles of the gas.

Definition of molar mass

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

Molar mass of the sample of gas

In this case you know:

P= 0.980 armV= 1.20 LT= 287 KR= 0.082 [tex]\frac{atmL}{molK}[/tex]n= ?

Replacing in the ideal gas law:

0.980 atm× 1.20 L= n× 0.082[tex]\frac{atmL}{molK}[/tex]× 287 K

Solving:

(0.980 atm× 1.20 L)÷ (0.082[tex]\frac{atmL}{molK}[/tex]× 287 K)= n

0.04997 moles= n

On the other hand, you know that the mass of the sample of gas is 0.458 grams. Replacing in the definition of molar mass:

[tex]molar mass=\frac{0.458 grams}{0.04997 moles}[/tex]

Solving:

molar mass= 9.17 [tex]\frac{g}{mol}[/tex]

How many moles of magnesium is 3.01 x 1022 atoms of calcium?

preferably a step by step answer....thank u<3

Answers

Answer:

0.03 mol

Explanation:

The equation relating the number of moles and number of atoms is:

Number of atoms = number of moles × 6.02 × 10²³

[6.02 × 10²³ is the Avogadro's constant and is the number of particles in 1 mole of any substance.]

By rearranging the equation, we can find the number of moles of calcium.

Number of moles = (3.01 × 10²²) ÷ (6.02 × 10²³)

Number of moles = 0.05 moles of calcium

Now the only data we know about these two elements are their Mr values, so we are going to find the number of moles of magnesium using ratio.

    Moles : Mr

0.05 mol : 40.1

           x  : 24.3

[we are going to assume that x is the number of moles of magnesium that we have to find out.]

Cross multiply the ratios.

40.1x = 0.05 × 24.3

x = 1.215 ÷ 40.1 = 0.03 mol
