Why do two oxygen atoms form a double covalent bond?
elena-s [515]

A lone oxygen atom has 6 electrons in its outer shell which is not very stable, whereas as full octet (8 outer shell electrons) is stable. In order to achieve this two oxygen atoms will share 4 electrons, each contributing 2 electrons. Since these electrons exist within the orbitals of both atoms, to oxygen atoms essentially achieve a full octet.

What is the molar mass of water (H2O)?
Sidana [21]

Answer:

The molar mass is: 18.02 g/mol.

Explanation:

  • Mass of two moles of Hydrogen atoms (H2) = 2x 1 g/mol = 2 g/mol.
  • Mass of one mole of water (H2O) = 2 g/mol + 16 g/mol = 18 g/mol.

1 mole of Hydrogen= 1.01, so if we have 2 moles of it here, that would be 2.02.

1 mole of Oxygen (that's all we have here)= 16.00

Once you add the two together (2.02+16.00), you will get 18.02.

I hope this made sense! Have a great day!

How many places are there for electrons in the third shell of an atom?
Dafna1 [17]
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
