How many moles of NO must react to form 5 moles of NO2 ?
2NO + O2 -> 2NO2
According to the balanced chemical equation, 2 moles of NO react to form 2 moles of NO2.
Therefore, 2 moles of NO would react to form 2 moles of NO2.
To find out how many moles of NO are needed to produce 5 moles of NO2, we can use a proportion:
2 moles of NO/2 moles of NO2 = x moles of NO/5 moles of NO2
Simplifying the proportion:
1 mole of NO / 1 mole of NO2 = x moles of NO / 5 moles of NO2
Cross multiply:
1 * 5 = 1 * x
5 = x
Therefore, 5 moles of NO must react to form 5 moles of NO2.
