Answer:
Ionic compounds, such as sodium chloride, are also highly soluble in water. Because water molecules are polar, they interact with the sodium and chloride ions. In general, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.

Your answer is 3.80 moles
Answer:
Place two of them as reactants.
Explanation:
- We have the two steps of reactions:
1) N₂(g ) + O₂(g) → 2NO(g).
2) 2NO(g )+ O₂(g) → 2NO₂(g).
- Adding the two equation with cancelling the intermediate (NO), we get:
<em>N₂(g ) + 2O₂(g) → 2NO₂(g).</em>
<em></em>
NO is cancelled out because there is one in each equation in the products side in eq. 1 and in oriduct side in eq. 2.
<em>So, we place two of oxygen as reactants.</em>
