The paper in the straw makes the soda fizz.
Answer:
kJ/mol
Explanation:
Given and known facts
Mass of Benzene
grams
Mass of water
grams
Standard heat capacity of water
J/g∙°C
Change in temperature ΔT
°C
Heat

Heat released by benzine is - 7.82 kJ
Now, we know that
grams of benzene release
kJ heat
So,
g benzine releases

kJ/g
mol C6H6
Heat released

kJ/mol
Beta radiation / decay would likely occur when the ratio of protons to neutrons is below the band of stability.
Technically speaking, yes you can. Using a microscope though.
