Chemical reaction changes the components of the reactant and often yield products that are chemically different from the reactants. While physical reactions do not change the components of the reactants.
it is true for your question
Sensory is the answer to your question .
Basically, every moles of H2O has around 6.022 x 10^23 Molecules
So for 2.00 moles, the amount of molecules would be :
2x 6.022 x 10^23
= 12.044 x 10^23
No I don't think it works that way. What you could do is drink one energy drink, wait 5 hours and then drink another.
