Answer:
Half-reactions:
Cr³⁺ + 1e⁻ → Cr²⁺; Zn → Zn²⁺ + 2e⁻
Net ionic equation:
2Cr³⁺ + Zn → 2Cr²⁺ + Zn²⁺
Explanation:
The Cr³⁺ is reduced to Cr²⁺:
<h3>
Cr³⁺ + 1e⁻ → Cr²⁺ -Half-reaction 1-</h3>
Zn is oxidized to Zn²⁺:
<h3>
Zn → Zn²⁺ + 2e⁻ -Half-reaction 2-</h3>
Twice the reduction of Cr:
2Cr³⁺ + 2e⁻ → 2Cr²⁺
Now this reaction + Oxidation of Zn:
2Cr³⁺ + 2e⁻ + Zn → 2Cr²⁺ + Zn²⁺ + 2e⁻
<h3>2Cr³⁺ + Zn → 2Cr²⁺ + Zn²⁺ - Net ionic equation</h3>
Definitely definite mass because liquids can take on any shape and can have different volumes.
Answer:
The government raised taxes
Explanation:
France had monarchy as its form of government. After the King of France had borrowed heavily to retain his extravagant lifestyle as well as the fact that the Kingdom of France was largely indebted, the king had no other option but to increase taxes paid by commoners in France.
This happened in an era of bad harvests and famine. The commoners depended mostly on bread to survive. This made the cost of bread to alarmingly increase and most people were hungry and starving.
These happenings led to the French revolution.
