Answer:
427.5g
Explanation:
Given parameters:
Number of moles = 4.5moles
Unknown:
Mass of MgCl₂ = ?
Solution:
To solve this problem;
Mass = number of moles x molar mass
Molar mass of MgCl₂ = 24 + 2(35.5) = 95g/mol
Mass = 4.5 x 95 = 427.5g
Answer:
The process in which energy is emitted by one object ,transmitted through .......
Ranking of the ions in each set in order of decreasing size -
Cs+ > Ba²⁺ > Sr²⁺
Cs+ has the biggest size, because its more downward (compared to Sr2+) and more to the left (compared) ot Ba2+.
Sr2+ has the smallest size because it's more upwords (compared to Cs+ and Ba2+).
For isoelectronic ions, the greater the nuclear charge , the greater is the attraction for electrons and smaller is ionic radius. In other words, size of the isoelectronic ions decreases with increase in atomic number.
Cl3+ has the smallest ion among all.
