I have done this question before and even though you didn’t provide the options. I think the correct option is elements
Answer:
Ionization energy, electronegativity, and lattice energy are the factors that influence the formation of ionic bonds of elements.
Using these Elements. Here would be the 4 ionic compounds.
CaF2
VF5
CaS
V2S5
Answer:
19.3 moles
Explanation:
In order to calculate the number of moles of Chlorine gas from the volume, we have to calculate its mass from its known density using the formula:
Density (g/L) = mass (g) /volume (L)
Density of Chlorine gas= 3.2g/L
Volume = 428L
3.2 = mass/428
mass = 428 × 3.2
mass = 1369.6g
Using mole = mass ÷ molar mass
Molar mass of chlorine (Cl2) = 35.5 × 2
= 71g/mol
mole = 1369.6 ÷ 71
mole = 19.2901
mole = 19.3 moles
