I believe the third choice is correct.
This can be proven by the fact that to find the molar mass of a compound, you simply add the molar masses of all the atoms within the compound
Hope this helps
Equilibrium occurs when forward and reverse directions of a reversible reaction occur at the same rate so there is no overall change in the amounts of reactants and products.
Answer:
Fr
Explanation:
Francium (Fr) has the lowest ionization energy, with a value of 4.0727eV. This ionization energy increases as one advances in a period, being greater in the group of nonmetals.
Answer:
0.00000363618
could be wrong.
double check me someone or just trust me
(don't blame me if you get it wrong)
Answer:
Protons= 11
neutrons= 12
electrons = 10
Explanantion:
Look for Na on periodic table
Atomic Number = 11
Atomic Mass = 23 (round it to be an integer)
Number of protons = Atomic number = 11
Number of neutrons = Atomic mass - atomic number = 23-11 =12
Number of electrons = 11 - e = ´+1 , electrons = 10
