Answer what there is no question
Potassium carbonate, K2CO3, sodium iodide, NaI, potassium bromide, KBr, methanol, CH3OH, and ammonium chloride, NH4Cl, are solub
just olya [345]
Answer:
A. K₂CO₃
Explanation:
The chemical reaction showing the ions produced on dissolving Potassium carbonate in water is:
K₂CO₃ ⇒ 2K⁺ + CO₃²⁻
Number of ions produced = 2 + 1 = 3
The chemical reaction showing the ions produced on dissolving sodium iodide in water is:
NaI ⇒ Na⁺ + I⁻
Number of ions produced = 1 + 1 = 2
The chemical reaction showing the ions produced on dissolving potassium bromide in water is:
KBr ⇒ K⁺ + Br⁻
Number of ions produced = 1 + 1 = 2
The chemical reaction showing the ions produced on dissolving ammonium chloride in water is:
NH₄Cl ⇒ NH₄⁺ + Cl⁻
Number of ions produced = 1 + 1 = 2
<u>The largest number of dissolved particles per mole of dissolved solute is produced by Potassium carbonate.</u>

Since N2 is a covalent bond, the lewis dot structure of N2 would have a triple bond. Each bond contains 2 electrons, so if it has a triple bond it contains 6 electrons.
Calculate the number of valence electrons of N2
N= 2x 5 = 10
N2 has a total of 10 valence electrons, to become stable each N atom needs 8 electrons.
So, therefore, 6 electrons would have to be a part of covalent bonds because they share 6 electrons in a triple bond.
