Water has highest surface tension
Answer: Option (c) is correct
<u>Explanation:</u>
There are molecules present in every liquid. Attachment of these molecules with each other gives rise to surface tension. It is the result of intermolecular forces. It is due to surface tension the insects float on a liquid.
The water has the highest surface tension. it is because molecules present on the surface of the water are held together by very strong hydrogen bonds. There is high attraction among the molecules of water.
<span>-Products formed by the forward
reaction may react with each other to regenerate the reactants.
-When reactants are mixed, they will begin to react at a forward reaction rate particular to that chemical reaction.
- As reactants are depleted and products are formed, however, the rate of the forward reaction begins to slow, and the rate of the reverse reaction begins to increase.</span>

Answer:
They are called homogenous mixtures. If you put sand into a glass of water, it is considered to be a mixture. You can always tell a mixture, because each of the substances can be separated from the group in different physical ways. You can always get the sand out of the water by filtering the water away.
