Answer:
21H deuterium (D), 31H is tritium (T), 11H is hydrogen
Explanation:
11H: it has the greatest abundance, it has only one proton (it does not have neutrons).
21H (D): it has a proton and a neutron in its nucleus.
31H (T): it has a proton and two neutrons in its nucleus.
Remember that isotopes have the same atomic number, but a different mass number (elements in the number of neutrons differed).
<span>grape juice
pOH = -log[1.4*10⁻¹⁰]</span>≈9.6
pH=14-pOH=14-9.6=4.4
orange juce
pH= -log[1.8*10⁻⁴]=3.7
Orange juice has lower pH, so it is more acidic.
