Answer: Molecules of gas are usually far apart and can be compressed unlike molecules of liquids.
Explanation:
The molecules of gases are usually far apart, moving freely and randomly, occupying extra space in the containing vessel. Hence, when compressed to become closely packed, gases have lower volume.
However, unlike gases, the molecules of a liquid are restricted, move less freely and occupy no extra space. Hence, liquids cannot be compressed, and their volume remains the same in their containing vessel.
The average weight of an adult male is 750 newtons. In computing for weight in newtons. W = ma; where m = weight in kilograms and a = acceleration due to gravity which is equal to 9.81 m/sec2.
The balanced chemical equation is:
2H2 + O2 ---> 2H2O
We are given the amount of the product produced from the reaction. This will be the starting point for the calculations.
355 g H2O ( 1 mol H2O/ 18.02 g H2O) ( 1 mol O2 / 2 mol H2O ) ( 32 g O2 / 1 mol O2 ) = 315.205 g O2
To get the number of liters of water vapor produced from the combustion of methane gas, we just need the stoichiometric ratio of water to methane which is 2:1. So the number of liters of water vapor from 13.3 liters of methane is 26.6 liters.
Because if you start at one for example you starting at a extra cm/m/mm. So when you get your measurement result it will be wrong by just one cm/m/mm. Hope this wasn't too confusing.
