Answer:
In an ionic bonds, the metal loses electrons to become a positively charged cation, In which the nonmetal accepts those electrons to become a negatively charged anion.
Explanation:
Answer:
4.09 × 10⁻² g
Solution:
As we know that,
1 mol of Fe₂O₃ is equal to = 159.69 g
So,
2.56 × 10⁻⁴ mol will be equal to = X g
Solving for X,
X = (159.69 g × 2.56 × 10⁻⁴ mol) ÷ 1 mol
X = 0.04088 g
Or,
X = 0.049 g
Or,
X = 4.09 × 10⁻² g
<h3><u>Answer;</u></h3>
C. The equilibrium position will shift away from what was added to lower its concentration.
<h3><u>Explanation;</u></h3>
- Le Chatelier's principle states that; if a system at equilibrium is disturbed, the equilibrium position will shift to counter the effects of the disturbance.
- At equilibrium, the system is disturbed when a change in conditions forces it temporarily out of equilibrium. There are three common disturbances:
1. Change in concentration.
2. Change in pressure (caused by a change in volume).
3. Change in temperature.
