Potassium Iodide or KI is an ionic compound and dissolves to water since the two are polar substances. Like dissolves like. As KI is dissolved into water, the KI molecules dissociates into ions, the K+ and I- ions. Water molecules can stabilize these ions. The K+ ions attracts the negative side of H2O molecules which is the oxygen side while the I- ions attracts the positive side of H2O molecules or the hydrogen side.
The answer is option C 7.60 M
Answer:
0.675 mol
Explanation:
Step 1: Write the balanced equation
2 Al + Fe₂O₃ ⇒ 2 Fe + Al₂O₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of Fe to Al₂O₃ is 2:1.
Step 3: Calculate the moles of Al₂O₃ produced when 1.35 moles of Fe are produced
We will use the established molar ratio.
1.35 mol Fe × 1 mol Al₂O₃/2 mol Fe = 0.675 mol Al₂O₃
Answer:
the molecules stop sliding and tumbling all over each other
