Answer:
• 1 kilocaloric equals 1000 gram calories
• 1 kilocalorie is equals to 4184 Joules of energy.
Explanation:
One kilocalorie is equals to 1000 gram calories because one kilo is equals to or have 1000 grams. One kilocalorie is equals to 4184 Joules of energy while on the other hand, one calorie is equals to 4.184 Joules of energy because one calorie is 1000 times smaller than Kilocalorie so calorie has also 1000 times lower energy than kilocalorie. Kilo is the prefix which means 1000 so we can say that One kilocalorie is equals to 1000 gram calories.
Equation is as follow,
<span> SnCl</span>₂ <span> + PbCl</span>₄<span> </span>→ <span>SnCl</span>₄ <span> + PbCl</span>₂
Oxidation State of Sn on left hand side in SnCl₂ is +2, while that in SnCl₄ on right hand side is +4. Means Sn has lost two electrons. Hence, it is oxidized and has worked as a reducing agent (has reduced Pb from Pb⁺⁴ to Pb⁺²).
Oxidation State of Pb on left hand side in PbCl₄ is +4, while that in PbCl₂ on right hand side is +2. Means Pb has gained two electrons. Hence, it is reduced and has worked as an oxidizing agent (has oxidized Sn from Sn⁺² to Sn⁺⁴).
By using their knowings about other things similar to the research that they need to do and use that to compare what they find.
