Answer:
Covalent bonds are formed when electrons are shared between elements that are nonmetals. The ammonium ion, NH+4 , would have covalent bonds because both nitrogen and hydrogen are nonmetals. ... The rest of the bonds all contain electrons from both hydrogen and nitrogen, so they would be considered ordinary covalent bonds.
Answer:
The concentration of the resulting solution in parts per million is 177.97
Explanation:
Parts per million (ppm), is a unit of measure for concentration that refers to the number of units of the substance per million units of the set.
The concentration in parts per million expressed in mass / mass is calculated by dividing the mass of the solute (ms) by the mass of the solution (md, sum of the mass of the solute and the mass of the solvent), both expressed in the same unit and multiplied by 10⁶ (1 million).

So, being:
- md: 0.089 grams of KI + 500 grams of H₂O= 500.089 grams
Replacing:

ppm= 177.97
<u><em>The concentration of the resulting solution in parts per million is 177.97</em></u>
