Answer:
C. Transition metals
Explanation:
Out of the answers transition metals have the most elements on the periodic table.
Not sure but I would say because each orbital around the nucleus of the atom resembles a fuzzy cloud around the nucleus!
Answer: The given statement is false .
Explanation:
Noble gases are least reactive elements in the periodic table. Noble gases have fully filled stable electronic configuration which the reason of their inert and lest reactive nature.
For example : Helium. Neon, argon etc.
Answer:
Explanation:
Data:
p₁ = 1 bar; V₁ = 5 L; T₁ = 0 °C
p₂ = 1 bar; V₂ = ?; T₂ = 45 °C
The pressure and the number of moles are constant, so, to calculate the volume, we can use Charles' Law.
Calculations:
(a) Convert temperatures to kelvins
T₁ = (0 + 273.15) K = 273.15 K
T₂ = (45 + 273.15) K = 318.15 K
(b) Calculate the new volume
