Question

Be sure to answer all parts. what volumes (in liters) of carbon monoxide and oxygen gas must react according to the equation 2co(g) + o2(g) → 2co2(g) to form 4.86 l of carbon dioxide? what is the volume of co?

Answer 1

The volume of oxygen gas and carbon monoxide that need to react is calculated as follows

write the equation for reaction

2CO +O2= 2CO2
the reacting ratio of CO:O2:CO2 is 2:1:2 from the equation above therefore

the volume of O2 = 4.86l x 1/2=2.43 L of O2

the volume of CO = 4.86 x2/2 = 4.86 L of CO
