7.1g N2 (1mol N2/ 28.02g N2)(3 mol H2/ 1 mol N2)(2.0158g H2/ 1 mol H2) = 1.5 g H2
We need theoretically 22,23 moles hydrogen.
Six
six valence electrons.....It only requires two more to complete octet....
The mass of nitrous oxide is 262,8 g.

During the burning (oxidation) of carbon no hydrogen is released.

Only in terms of cost, time to complete, resources-those kinds of measures. A census provides complete information if done properly which is not possible with just a sample. A sample is always subject to sampling error.
The polymerase chain reaction machine (often known as the PCR machine) can create an indefinite amount of copies of DNA samples.

There are 67 sample countries.
While many reactions involve oxygen, only combustion reactions require oxygen as a reactant.
2 moles, if you can find the proper catalyst, or set of reactions to complete the reaction.
During the burning (oxidation) of carbon no hydrogen is released.
Propane is C3H8 and the combustion equation is C3H8 + 5O2 ==> 3CO2 + 4H2OSo the complete combustion of 1 mole of propane requires 5 moles of oxygen.
Many statistical statements for a population which are based on a sample are not valid if the sample is not representative.
