To calculate the amount of heat transferred when an amount of reactant is decomposed, we must look at the balanced reaction and its corresponding heat of reaction. In this case, we can see that 252.8 kJ of heat is transferred per 2 moles of CH3OH used. When 22 g of CH3OH is used, 86.9 kJ is absorbed.
Answer:
What information can climatologists learn from fossils? Fossils of plants and animals can show adaptations that organisms had for a particular type of climate that existed millions of years ago. Climatologists look at many pieces of evidence to study climate change. These pieces of evidence can support each other.
Explanation:
,.,
Answer:
Because the molecules have not been in water so they are not moving around each other
Explanation:
<h2>
Hello!</h2>
The answer is:
The percent yield of the reaction is 32.45%
<h2>
Why?</h2>
To calculate the percent yield, we have to consider the theoretical yield and the actual yield. The theoretical yield as its name says is the yield expected, however, many times the difference between the theoretical yield and the actual yield is notorious.
We are given that:
![ActualYield=37.6g\\TheoreticalYield=112.8g](https://tex.z-dn.net/?f=ActualYield%3D37.6g%5C%5CTheoreticalYield%3D112.8g)
Now, to calculate the percent yield, we need to divide the actual yield by the theoretical and multiply it by 100.
So, calculating we have:
![PercentYield=\frac{ActualYield}{TheoreticalYield}*100\\\\PercentYield=\frac{37.6g}{112.8g}*100=0.3245*100=32.45(percent)](https://tex.z-dn.net/?f=PercentYield%3D%5Cfrac%7BActualYield%7D%7BTheoreticalYield%7D%2A100%5C%5C%5C%5CPercentYield%3D%5Cfrac%7B37.6g%7D%7B112.8g%7D%2A100%3D0.3245%2A100%3D32.45%28percent%29)
Hence, we have that the percent yield of the reaction is 32.45%.
Have a nice day!
