A0.3423 g sample of pentane, c5h12, was burned in a bomb calorimeter. the temperature of the calorimeter and the 1.000kg of water contained therein rose from 20.22 degrees celcius to 22.82 degrees celcius. the heat capacity of the calorimeter is 2.21 kj/c. the heat capacity of water = 4.184 j/g c. a. how much heat was given off during combustion fo the sample of pentane. answer = 16.6 kjb. what is the heat of combustion, in kilojoules, per gram of pentaneanswer = 48.6 kj/g

Δ

Explanation:

Hello,

A. In this part, we must include the heat effect for pentane and water:

B. In this part, we just consider the previously computed heat and divide it by the sample of pentane as follows:

Δ

Best regards.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
