We know that the molar mass of N is 14 and O is 16,
therefore the molar mass of N2O is:
molar mass N2O = 14 * 2 + 16 = 44 g/mol
The number of moles:
moles N2O = 0.187 / 44
moles N2O = 0.00425 mol
There are 2 moles of N per 1 mole of N2O hence:
moles N = 0.00425mol * 2
<span>moles N = 0.0085 mol</span>
Answer:
H₂ + O₂ → H₂O
Now, check that oxygen has two atoms on the left and one on the right
so, you put 2 on the right side
H₂ + O₂ → 2H₂O
oxygen is balanced so, add 2 on H₂ to balance out hydrogen
THE FINAL BALANCED EQUATION:
<h2>
2H₂ + O₂ → 2H₂O</h2>
hmm, i not sure i come back later with the answer.
1st place is in the air !
carbon dioxide has carbon in it and we release it all the time, when we're awake and when were asleep.
another place would be the gas that cars release. this gas is known as carbon monoxide.
Multiply this number by avogadro's number- 6.02 times 10^23
