Answer:

The middle Hydrogen atom is bonded to two instead of one atom

Oxygen is bonded to one instead of two atoms

Oxygen has three instead of two lone pairs of electron.

Explanation:

If we look at the structure, we will notice that it does not satisfy the basic principles of valency.

Hydrogen has a valency of 1. However, the middle hydrogen atom is bonded to two atoms instead of only one atom - the other atom of hydrogen and an atom of oxygen.

Secondly, oxygen has three lone pairs instead of two lone pairs, hence it is bonded to only one instead of two atoms. This does not correspond to the known valency of oxygen.

Answer: Hydrogen cannot have more than two electrons.

Hydrogen bonds to only one other atom at a time.

There are too many electrons in the final structure.

Which of the following claims may be made based on your observations? (You will recieve negative points for wrong answers.)
Ostrovityanka [42]

Answer:

D, E and F

Explanation:

About tetrachloro cobalt complexes, the following facts have been observed  

  • Color of the tetrachloro cobalt complexes is blue.
  • They do not decompose on heating that means synthesis of tetra chloro is endothermic.

About hexa aqua cobalt complexes, the following facts have been observed  

  • Color of the hexa aqua cobalt complexes is pink color.
  • They decompose on heating and remain stable on cooling that means process of synthesis of hexa aqua cobalt complexes is exothermic.

Based on above, the correct statements are:

The correct is chloro cobalt complex is blue and aqua cobalt  

complex is pink.  

The chloro complex is favored by heating.

If the chloro complex is a product, then the reaction must be endothermic.

The correct options are D, E and F.

Calculate the concentration 3.8g of copper sulfate, CuSO4 dissolved in 250cm4 of water
11Alexandr11 [23.1K]

Answer:

Molarity = 0.08 M

Explanation:

Given data:

Mass of copper sulfate = 3.8 g

Volume of water = 250 cm³  (250/1000 = 0.25 L)

Concentration of solution = ?

Solution:

Number of moles of copper sulfate:

Number of moles = mass/molar mass

Number of moles = 3.8 g/ 159.6 g/mol

Number of moles = 0.02 mol

Concentration:

Molarity = Number of moles / volume in L

By putting values,

Molarity = 0.02 mol / 0.25 L

Molarity = 0.08 mol/L

Molarity = 0.08 M
