on the basis of hybrid formation, explain the existence of compounds of column IVA such as CH4 when the elements of column IVA only have two unpaired electrons in normal state

Answers

Answer 1

Answer:

CH4 compound is formed by sharing of electrons with hydrogen atom. They are bonded by ionic bonds. They undergo sp^3 hybridization.

Explanation:

The group 4A elements have 4 electrons in their valence shell or highest energy orbitals ie 2s^2, 2p^2

They share electrons from other elements thereby stabilising their valence shell and form bonds between them. The bonds can be covalent or ionic. It undergoes sp^3 hybridization.

The four valence electrons of the carbon atom are distributed equally in the hybrid orbitals, and each electron of carbon pairs with an electron of hydrogen atom when the C–H bonds form.

aprons are used to cover your body (most people use la coats though) and goggles are used to cover your eyes.

A Safety shower should be used for more significant spills.

An MSDS (Material Safety Data Sheet) describes important safety and reactivity information about a chemical.

I hope this helps. Let me know in the comments if anything is unclear.

Magnetite, Fe3O4, is a ferrimagnetic, rather than a ferromagnetic material that contains different iron isotopes. How is it different from ferromagnetic minerals? A) It has opposing magnetic moments.
B) It can be spontaneously magnetized.
C) Its magnetization is temperature dependent.
D) The electrons in the iron spin in the same direction.

Answers

Answer:

Option A

Explanation:

Ferromagnetic materials have the property to be attracted to magnets while ferrimagnetic material is the magnetic property of materials having atomic moments aligned in opposite directions. In ferrimagnetic material as the magnetic moments are aligned in opposite direction, they cancel out the magnetic field.

Answer: A. It has opposing magnetic moments.

Explanation:

Magnetite , Fe3O4 is Ferrimagnetic and quite different from Ferromagnetic minerals because it's magnetic moments are aligned in opposite directions.

The accepted value for the percent by mass of water in a hydrate is 36.0%. In a laboratory activity, a student determined the percent by mass of water in the hydrate to be 37.8%. What is the percent error for the student's measured value?(1) 5.0% (3) 1.8%

(2) 4.8% (4) 0.05%

Answers

The original or accepted value for the percent by mass of water in a hydrate = 36%
Percen by mass of water in the hydrate determined by the student
in the laboratory = 37.8%
So the difference between the actual and the percent by mass in water determined by student = (37.8 - 36.0)%
   = 1.8%
So the percentage of error made by the student = (1.8/36) * 100 percent
   = (18/360) * 100 percent
   = ( 1/20) * 100 percent
      = 5 percent
So the student makes an error of 5%. Option "1" is the correct option.
