Answer:
∴ No. of atoms in 0.01 moles of NaOH = 6.02×10
23
×0.01=6.02×10
21
Covalent bonds are formed when 2 neutral atoms come together to share a pair of electrons, where each atom contributes one electron each to be shared.
The covalent bond is kept together by the electrostatic attraction between the nuclei of the atoms and the shared pair of electrons.
Covalent bonds are usually formed between non metals with a small difference in their electro negativity.
the correct answer is
A. Neutral atoms coming together to share electrons
So the first one is yellow and the other one is white
The concentration is 5 g/L.
Concentration = mass/volume = 10 g/2 L = 5 g/L
