Submit your data by including the type of balance or scale, the precision of the balance or scale, the mass of the can of food, and a chart of your data. Record the masses using the correct significant digits. Write a conclusion evaluating your skills and address the following questions:

1) How did the experiment demonstrate accuracy in measuring when using the can of food? Give evidence for your answer.

2) How did the experiment demonstrate precision in measuring? Give evidence for your answer.

the maximum mass of nh3 is nh3 in grams

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.
