The chemical formula would dictate how many ions are present in a solution. It tells how many of what ion would dissociate in the solution. In every chemical reaction or dissociation reaction, it is important to remember that the number of each atoms on each side would be equal.
<h3>
Answer: 1.6 mol (option 5)</h3>
Explanation:
<u>Mole Ratio of O₂ : NO</u>
Based on the balanced equation, the mole ratio of O₂ : NO is 5 : 4
∴ for every mole of O₂ reacted, ⁴/₅ moles of NO is produced
<u>Moles of NO</u>
since the number of mol of O₂ = 2.0 mol
then moles of NO produced = 2.0 mol × ⁴/₅
= 1.6 mol
∴ the moles of nitrogen monoxide that will form if we start with 2.0 moles of oxygen is 1.6 mol (option 5).
Explanation:
Dissolve 93.52g of NaCl in about 400mL of distilled water, then add more water until final volume is 800mL. If starting with a solution or liquid reagent: When diluting more concentrated solutions, decide what volume(V2) and molarity (M2) the final soluble should be.
