when one of the hydrogen in methane (CH4) is replaced by hydroxyl group , then structurally methane resemble ? 1. methanol 2. ethanol 3. water 4. methanol and water​

Answer 1

$\huge\boxed{\underline{\mathcal{\red{❥A}\green{N}\pink{S}\orange{W}\blue{E}\purple{R}}}}$

Sea water is a mixture of salts and water which cannot be separated except by evaporation. Therefore, sea water is considered homogeneous.

Sea water also contains mud, decayed plant, etc., other than salts and water, so it is heterogeneous also.

Answer 2

Answer:

4) Methanol and Water

Explanation:

When one of the hydrogen in methane (CH4) is replaced by a hydroxyl group, then structurally methane resembles methanol and water.

Like water, it is a liquid with a boiling point which is abnormally high for a compound of its size and polarity.

The only way to extract salts from water in seawater is by evaporation. Seawater is therefore seen as homogenous.

Sea water is heterogeneous because it also contains other substances besides salt and water, such as mud, dead plants, etc.
