What is the single factor that classifies an element as a transition metal? Question 16 options:
2 answers:
Answer: Option (A) is the correct answer.
Explanation:
A transition element is defined as the element which has incompletely filled d-orbital.
For example, atomic number of chromium is 24 and its electronic configuration is .
Also, sometimes the s-orbital is completely filled and sometimes it is half-filled.
Hence, we can conclude that a single factor that classifies an element as a transition metal is that the highest occupied orbital is a "d" orbital.

Answer:
0.00369 moles of HCl react with carbonate.
Explanation:
Number of moles of HCl present initially = moles = 0.00600 moles
Neutralization reaction (back titration):
According to above equation, 1 mol of NaOH reacts with 1 mol of 1 mol of HCl.
So, excess number of moles of HCl present = number of NaOH added for back titration = moles = 0.00231 moles
So, mole of HCl reacts with carbonate = (Number of moles of HCl present initially) - (excess number of moles of HCl present) = (0.00600 - 0.00231) moles = 0.00369 moles
Hence, 0.00369 moles of HCl react with carbonate.
