Because science they need to know how food works and stuff like that u know?
The mass of one mole of H is 1.008 grams.
Answer: Option (c) is the correct answer.
Explanation:
It is known that like dissolves like. As cyclohexane is a hydrocarbon and we know that hydrocarbons are non-polar in nature. So, a non-polar compound will be soluble in a hydrocarbon.
For example, NaBr is an ionic compound and when it i added to liquid cyclohexane then it will not dissolve. Similarly, 
and HI are polar covalent compounds and they will not dissolve in liquid cyclohexane.
But 
is a non-polar compound. So, when it is added to liquid cyclohexane then it will readily dissolve.
Thus, we can conclude that pentane () will most likely dissolve in cyclohexane to form a solution.
Answer:
Storage battery oe cell
Explanation:
The storage battery or cell is a device that coverts chemical energy into light energy when required.
During charging of battery, there is some chemical changes in the battery and absorb energy. The absorbed energy is converted into electrical energy when connected to an external load.
Hence, the correct answer is "Storage battery or cell".
