Describe the molecular structure of water and explain why the water molecule is polar
pentagon [3]

Explanation:

Hybridization of O in H_2O = sp^3

So, water molecule has four hybrid orbitals.

Two hybrid orbitals form 2 sigma bond with two H atoms.

Remaining two hybrid orbitals are occupied by two lone pairs.

Because of lone pair-lone pair repulsion, shape of H_2O becomes bent.

Water molecule is polar because of difference in eletronegativities of O and H.

O is more electronegative as comapared to hydrogen. So bonding electrons get attracted towards O atom which results in the development of partial negative charge on O atom and partial positive charge on H atoms.

Because of development of partial negative and partial positive charge, water molecule becomes polar.

Molar mass c3h8
maksim [4K]

Answer:

1. 44.11 g

2. 36.03 g

3. 8.08 g

4. 81.7%

5. 18.3%

Explanation:

1. 12.01+12.01+12.01+1.01+1.01+1.01+1.01+1.01+1.01+1.01+1.01=44.11

2. 12.01×3= 36.03

3. 1.01×8= 8.08

4.(36.03/44.11)×100= 81.7%

5. (8.08/44.11)×100= 18.3%
