Salts that are from strong bases and strong acids do not hydrolyze. Salts that are from strong bases and weak acids do hydrolyze, which gives it a pH greater than 7. Salts of weak bases and strong acids do hydrolyze, which gives it a pH less than 7.
Answer:
ten atoms of hydrogen are present in one mole of caffeine.
Explanation:
Molecular formula of caffiene is given which is C3H10N4O2. It clearly shows that ten atoms of hydrogen are present. One mole is amount equal to one molecular weight of a molecule which is derived from molecular formula. So as moecular formula has ten atoms of hydrogen, one mole of caffeine has 10 atoms of hydrogen.
An alpha particle has a mass number of 4.
The mass number in the decay of uranium-234 to lead-214 decreases from 234 to 214, so by 20.
20 ÷ 4 = 5
5 alpha particles were emitted in this decay series. The answer is C.
I think it produces a ton of miles in one second.
