Answer:
The answer is D) Electrolytic cell
Explanation:
An electrolytic cell is a device used for the decomposition by the electrical current of ionized substances called electrolytes.
When the two electrodes are connected by a wire, electrical energy is produced, and a flow of electrons takes place from the electrode.
These cells are the closest thing to a galvanic battery.
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.
Explanation:
Given the amount of fluorine is ---- 1.25 mol.
What is the mass of given fluorine in grams?
Since
To get the mass of the substance in grams, multiply the given number of moles with the molecular mass of the substance.
Hence, among the given options, the correct answer is the last option that is
Multiply the atomic mass of fluorine by 1.25.
When you need heat to make reaction happen it is endothermic.
If heat was on the right side then type of reaction would be exothermic.
