Atomic number = 127 – 53=74 neutrons
<u>Answer:</u> The relation between the forward and reverse reaction is
<u>Explanation:</u>
For the given chemical equation:
The expression of equilibrium constant for above equation follows:
.......(1)
The reverse equation follows:
The expression of equilibrium constant for above equation follows:
.......(2)
Relation expression 1 and expression 2, we get:
Hence, the relation between the forward and reverse reaction is
Answer:
5.4 M.
Explanation:
- At complete neutralization: It is known that the no. of millimoles of acid equal that of the base.
<em>(MV)acid = (MV)NaOH</em>
M of acid = ??? M, V of acid = 35.0 mL.
M of NaOH = 3.0 M, V of NaOH = 63.0 mL.
∴ M of acid = (MV)NaOH / (V)acid = (3.0 M)(63.0 mL)/(35.0 mL) = 5.4 M.
Answer:
See explanation
Explanation:
According to the Journal of Chemical Education, Volume 80, No.8 (2003); "The first ionization energy of bismuth appears to be anomalous......It has been claimed that spin–
orbit coupling by the Russell–Saunders scheme would lower the ground state of Bi+ ..."
However, the involvement of d and f orbitals in Bi and Po implies that the outermost orbitals are poorly screened hence the drop between nitrogen and oxygen is not observed between Bi and Po.
The same argument could be extended to explain the reason why there not a corresponding drop between Ba and Tl is the sixth period even though they are in the same group as Be and B.
Answer: Your mass would be the same, but you would weigh less because the gravity on the moon is less than it is on Earth.
