Two chemical reactions are shown:
Nina [5.8K]

Answer: B

Oxygen acts as oxidator in the first reaction.

Explanation:

At reactant side:

Mg = 0

At product side:

MgO = 0

but Oxygen (O) = -2

Mg + O = 0

Mg + (-2) = 0

Mg - 2 = 0

Mg = 2

Magnesium is oxidized by OXYGEN from zero to +2

Oxygen acts as oxidator in the first reaction.

Give the hybridization for the br in bro4⁻.
elixir [45]

The hybridization for the Br in BrO4⁻ is sp^{3}. So, the correct option is (e).

In chemistry, the idea of combining atomic orbitals to create new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) is known as orbital hybridisation (or hybridization). These new hybrid orbitals are suitable for the pairing of electrons to form chemical bonds in valence bond theory.

Because more directional hybridised orbitals result in higher overlap when creating bonds, stronger bonds are formed, which favours the hybridization of orbitals. When hybridization takes place, this leads to more stable molecules.

One s orbital and three p orbitals combine to form four sp^{3} orbitals, each of which has a 25% s character and a 75% p character. This process is known as sp^{3} hybridization. Anytime an atom is surrounded by four groups of electrons, this kind of hybridization is necessary.

Which substance is most soluble in water? <br> 1) (NH4)3PO4<br> 2)Cu(OH)2<br> 3) AG2SO4<br> 4) CACO3
ivann1987 [24]

Answer: Option (1) is the correct answer.

Explanation:

When dissolved in water, ammonium phosphate (NH_{4})_{3}PO_{4} completely dissociates into ions and it gets attached to the opposite ends of water.

Therefore, it is soluble in water.

Whereas silver sulfate (Ag_{2}SO_{4}) slightly dissolves into water as it gives very less Ag^{+} ions. Therefore, silver sulfate has low solubility.

On the other hand, both Ca(OH)_{2} and CaCO_{3} are insoluble in water.

Thus, we can conclude that out of the given options, (NH_{4})_{3}PO_{4} is most soluble in water.
