How many hybrid orbitals are found in CCl4?

Answers

Answer 1

Answer:

CCl4

For central atom C

The formula to calculate hybridization is:

n= 1/2 [group no. central atom +no. of monovalent atoms attached to central metal atom (except oxygen) + magnitude of negative charge - magnitude of positive charge]

n= 1/2 [4 +4 + 0-0]

n= 1/2 [8)

The hybridization is sp3 and the electron geometry is tetrahedral

Answer 2

Answer: the answer is FOUR 4
hope this helps ;)

Conductivity in a metal results from the metal atoms having(1) high electronegativity(2) high ionization energy(3) highly mobile protons in the nucleus(4) highly mobile electrons in the valence shell

Answers

The answer is (4). You may recall hearing about the "sea of electrons" model of metals. Metals represent the ultimate case of delocalized (shared) valence electrons, and these delocalized valence electrons are what freely move around, conducting current through the body of the metal.

The correct answer is (4) highly mobile electrons in the valence shell

The explanation:

-A metal consists of a lattice of atoms, each with a shell of electrons. This is also known as a positive ionic lattice.

- The outer electrons are free todissociate from their parent atoms and travel through the lattice, creating a sea of electrons, his valence electrons are what freely move around making the metal a conductor.

-When an electrical potential difference is applied across the metal, the electrons drift from one end of the conductor to the other under the influence of the electric field.

If element x has 55 protons how many electrons does it have

Answers

Answer: 55

Explanation: A atom consists of a nucleus and electrons.Nucleus contain neutrons with no charge and protons with positive charge. The electrons bearing negative charge revolve around the nucleus.

An electrically neutral atom contains equal number of protons and electrons. Thus if a neutral element X contains 55 protons, it also contains 55 electrons.

If the element has 55 protons it is celcium and it also has 55 electrons. It has an atomic mass of 133 (132.9) so to get the number of neutrons you subtract the atomic mass and the number of protons.

Where are people exposed to chemicals?O A. Mostly in public buildings
O B. Only in the home
C. Mostly outside
O D. Everywhere

Answers

Answer:

I believe the correct answer is D.

Explanation:

You are breathing in dinitrogen and dioxygen. You exhale dinitrogen and carbon dioxide. And the atmosphere contains traces of other gases. You drink water. You have a wash with water, and soap. You eat carbohydrates and proteins. You ride to work on a vehicle powered by hydrocarbons, which spits out carbon dioxide exhaust fumes, and also some nitrogen oxides. And so your exposure to chemicals is pervasive, and unavoidable.

Explanation:

Which term is defined as a measure of the average kinetic energy of the particles in a sample?(1) temperature (3) thermal energy
(2) pressure (4) chemical energy

Answers

Answer: The correct answer is Option (1).

Explanation:

Average kinetic energy is defined as the average of the kinetic energies that is associated to the particles of the sample which are in random motion.

Temperature is the measure of the average kinetic energy of the particles. Formula used for calculating the average kinetic energy is given by:

$K=(3)/(2)(R)/(N_A)* T$

where,

K = kinetic energy

R = Gas constant

$N_A$ = Avogadro's constant

T = temperature

Kinetic energy is directly proportional to the temperature of the particle.

$\text{Kinetic energy}\propto \text{Temperature}$

As the temperature increases, the kinetic energy of the particles also increases and vice-versa.

Hence, the correct answer is option 1.

The answer is (1). Temperature is directly proportional to the average kinetic energy of the particles in any given sample of matter, and it is usually defined along those lines.
