The combustion of palmitic acid in a bomb calorimeter yields energy in the form of heat released upon oxidation. From a thermody
1 answer:
Answer:
"The same amount of energy" is the combustion of the same amount of palmitic acid in our body to yield.
Explanation:
A bomb calorimeter is an apparatus used to measure the amount of heat out or fascinated by a chemical reaction. This apparatus is airtight and has thermal insulation, which means that the organization doesn't alteration heat with the environments. So, by the variance of the temperature measured on the system (ΔT), the mass of a solution (m) and the specific heat of water (c) it's likely to compute the heat in a reaction that happens in aqueous solution, by the equation below:
Q =
The heat, or the energy, of the response doesn't depend on where the response is happening, so the sum of energy measured on the bomb calorimeter will be the same in our body.

Answer: The percent yield of this combination reaction is 41.3 %
Explanation : Given,
Mass of = 5.0 g
Mass of = 10.0 g
Molar mass of = 23 g/mol
Molar mass of = 71 g/mol
First we have to calculate the moles of and
.
and,
Now we have to calculate the limiting and excess reagent.
The balanced chemical equation will be:
From the balanced reaction we conclude that
As, 2 mole of react with 1 mole of
So, 0.217 moles of react with
moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and
is a limiting reagent and it limits the formation of product.
Now we have to calculate the moles of
From the reaction, we conclude that
As, 2 mole of react to give 2 mole of
So, 0.217 mole of react to give 0.217 mole of
Now we have to calculate the mass of
Molar mass of = 58.5 g/mole
Now we have to calculate the percent yield of this reaction.
Percent yield =
Actual yield = 5.24 g
Theoretical yield = 12.7 g
Percent yield =
Percent yield = 41.3 %
Therefore, the percent yield of this combination reaction is 41.3 %
Answer:- The direction of the polarity of the indicated bond is from carbon to oxygen.
Explanations:- There are two types of covalent compounds, polar and non polar. If the bond is between two same atoms for example, H-H, Cl-Cl etc then the bond is non polar. If the bond is between two different atoms then the bond would be polar. The direction of the polarity is from loss electron negative atom to more electron negative atom.
Oxygen is more electron negative than carbon. So, being more electron negative, the bonding electrons are more towards oxygen and it cases partial negative charge on oxygen and partial positive charge on carbon. The direction of the polarity is from less electron negative carbon to more electron negative oxygen.
It is shown in the diagram below:
