Answer: 241.6 grams of CO2
Explanation: you take 84.3 grams C5H12 and divide it by 72.15 grams of C5H12(which is the molar mass) you take that answer and calculate the mols of CO2 by multiplying the 1.168 you got before and multiply it by 5. You take the answer you get from that and multiply it by the molar mass of CO2 and get the theoretical yield and then you just plug it in. 94= (x/257.02)x100 and solve to find x which is the actual yield.
Na (sodium) and Rb (rubidium) have the most similar chemical properties. They're both Alkali metals, found in the first column of the periodic table.
The time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.
<h3>What is half-life?</h3>
Half-life is the time half-time of the total decay of any element.
Given that, Initial amount = 970 grams
Final amount = 98 grams
Half life = 13 minutes
To find the half life
![Half life \times \dfrac{\dfrac{initial \;amount}{final\;amount} }{log2} \\\\\\13 \times \dfrac{\dfrac{970 }{98} }{log2} = 9.897](https://tex.z-dn.net/?f=Half%20life%20%5Ctimes%20%5Cdfrac%7B%5Cdfrac%7Binitial%20%5C%3Bamount%7D%7Bfinal%5C%3Bamount%7D%20%7D%7Blog2%7D%20%5C%5C%5C%5C%5C%5C13%20%5Ctimes%20%5Cdfrac%7B%5Cdfrac%7B970%20%7D%7B98%7D%20%7D%7Blog2%7D%20%3D%209.897)
Thus, the time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.
