Answer:
Explanation:
F2 have the weakest attraction to each other because of higher electronegativity when they are brought close to each other they repel each other
Cobalt because it has an atomic mass of 58 and 33 neutrons.
Answer:
yes, that is not a question, that's a statement
Answer is: mass of lithium fluoride is 3,732 grams.
m(solution) = 18,66 g.
ω(solution) = 20% = 20% ÷ 100% = 0,2.
m(LiF) = ?
ω(solution) = m(LiF) ÷ m(solution).
m(LiF) = ω(solution) · m(solution).
m(LiF) = 0,2 · 18,66 g.
m(LiF) = 3,732 g.
