Answer:- none
Explanations:- For naming hydrocarbons we use the suffix -ane, -ene and -yne.
-ane is used when we have only single bonds between all carbons. -ene is used if there is any double bond between two carbons and the -yne is used if there is any triple bond between two carbons.
The given name of the compound is propane. It ends at -ane and so it's an alkane and must have single bonds between all the carbons it has. So, there are zero double bonds present in .
This is also clear from the below lewis dot structure of the compound.
As we know that
Polarity exists due to presence of charges. And charges are generated in molecules due to
Electronegativity differences. The element with higher electronegativity will have
partial negative charge, while element with less electronegativity will have
partial positive charge. This partial positive and partial negative charge on a molecule makes it
polar.
Polarity mainly depends upon the
shape of a molecule. For example, In
water Oxygen being more electronegative is partial negative and Hydrogen being less electronegative is partial positive. It is polar and has a
bent structure. It means the two bond moments are not cancelling each other hence the water molecule has a net dipole moment of
1.84 D.
Secondly,
CO₂ (Carbon dioxide) also has a more electronegative Oxygen atom and less electronegative Carbon atom. In this case the net dipole moment on CO₂ is
zero. This is because the structure of CO₂ is
linear. As the two dipoles being equal and opposite
cancel out the effect of each other making the CO₂ molecule
non-polar.
Answer: The quantity of heat produced by the reaction is +26710.656J
Explanation:
Quantity of Heat, Q = mass * specific heat capacity *temperature change
Q = mCpTc, where m= mass, Cp= specific heat capacity, Tc is temperature change
m= 210.0g, Cp=4.184J/(g · oC), Tc= 57.6 - 27.2 = 30.4 oC
Q = 210.0g *4.184J/(g · oC) * 30.4 oC
Q = +26710.656J
Therefore, the quantity of heat produced by the reaction is +26710.656J.
Note: <em>Even though heat is given out by the system and is normally written as a negative value to indicate that heat is lost, the answer is written as a positive decimal number according to instruction.</em>
