Yes, you should memorize them. While it is easy to predict them by looking at a periodic table, you should still have a strong grasp of simpler chemistry such as this before more challenging topics are taught.
<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).
Compared to a solid, the molecular bonds of a liquid are B. Weak.
