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)
=4
The hybridization is sp3 and the electron geometry is tetrahedral
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.
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.
c. external conflict.
b. climax.
d. internal conflict.
Answer:
The increase in CO2 will affect crop plants by causing in increase in global warming and therefore, will stunt plant growth and cause excessive heat to kill the plants.

O B. Only in the home
C. Mostly outside
O D. Everywhere
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.
Answer:
d
Explanation:
(2) pressure (4) chemical energy
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:
where,
K = kinetic energy
R = Gas constant
= Avogadro's constant
T = temperature
Kinetic energy is directly proportional to the temperature of the particle.
As the temperature increases, the kinetic energy of the particles also increases and vice-versa.
Hence, the correct answer is option 1.
