Answer: The coefficient of nitrogen in the given equation is 2.
Explanation: The reaction for the oxidation of methamphentamine with oxygen gas in the body is given by:
By Stoichiometry,
4 moles of methamphentamine reacts with 55 moles of oxygen gas to produce 40 moles of carbon dioxide gas, 30 moles of water and 2 moles of nitrogen gas.
Coefficient of
Coefficient of
Coefficient of
Coefficient of
Coefficient of
Hence, the coefficient of nitrogen in the given equation is 2.
Answer : The mass of water produced will be 32.78 grams.
Explanation : Given,
Mass of = 21.9 g
Molar mass of = 72.15 g/mole
Molar mass of = 18 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of .
The balanced chemical reaction will be,
From the balanced reaction we conclude that
As, 1 mole of react to give 6 moles of
So, 0.3035 moles of react to give
moles of
Now we have to calculate the mass of .
Therefore, the mass of water produced will be 32.78 grams.
