Answer: the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure
Explanation:
D. layer B is younger than layer G.
Here, most electronegative element = Fluorine (4)
Least electronegative = Potassium (0.82)
In short, Fluorine(F) & Potassium (K) have greatest difference in electronegativity of about 3.18
Hope this helps!
Answer:
The solution is 50 %wt
Explanation:
50% wt is a sort of concentration and means, that 50 g of solute (in this case, the potassium bromide) dissolved in 100 g of water.
It is the same to say, that there are 50g of KBr for every 100g of H₂O
