the cell will expand as water moves into it.
Answer:
if you meant moles this is the answer 1
mol of lithium bromide has a mass of
86.85g⋅mol−1. You have 2.6 moles
Explanation: mass = 86.85g⋅ mol−1× 2.6 mol
Answer: Option (A) is the correct answer.
Explanation:
Electronegativity is the ability of an atom to attract electrons towards itself.
When we move across a period in the periodic table then there occurs an increase in the electronegativity of the elements because of decrease in their atomic size.
This is because electrons add to the same sub-shell and due to electrostatic force of attraction from the nucleus they get pulled closer towards the nucleus leading to shrinkage in size.
And, smaller is the size of an atom more readily it will attract an electron.
Therefore, we can conclude that electronegativity increases across a period.
