Option a is right answer that is reverse osmosis.

The correct option is A.

Reverse osmosis is a special type of filtration, which involves the passing of a solvent through a semi permeable membrane in the direction that is opposite to that of natural osmosis. Pressure is always used in this process to enforce separation. The method is usually used to remove ions, fine dust particles, molecules and larger particles from solvents. The method is especially popular in water treatment and purification.

3. Heat can be thought of as the movement of particles (molecules etc). The faster they move the hotter things are. Energy of movement is called kinetic energy. Temperature is a measure of the average kinetic energy of the particles, while thermal energy is the total kinetic energy of the particles.

Need help with this chem question thanks
IRISSAK [1]

Answer:

The answer to your question is letter A.

Explanation:

Isomers are molecules that have the same molecular formula but have a different structure. The molecule from which are looking an isomer has 5 carbons and 1 double bond. Then we need to look for another molecule with these components.

A.- This molecule has 5 carbons and 1 double bond, This structure is an isomer of the first one.

B.- This molecule has 3 carbons and 1 double bond, it's not an isomer of the first structure.

C. This molecule has 4 carbons and 1 triple bonds, it's not an isomer of the first structure.

D. This molecule has 5 carbons but it doesn't have any double bond, then it's not an isomer of the first structure.
