Given the balanced equation for the reaction of butane and oxygen: 2C4H10 + 13O2 > 8CO2 + 10H2O + energy How many moles of carbon dioxide are produced when 5.0 moles of butane react completely? * 5.0 mol 10. mol 20. mol 40. mol

Answer : The number of moles of carbon dioxide produced is, 20. moles

Explanation :

The given chemical reaction is:

From the balanced chemical reaction we conclude that,

As, 2 moles of butane react to give 8 moles of carbon dioxide

So, 5.0 moles of butane react to give moles of carbon dioxide

Thus, the number of moles of carbon dioxide produced is, 20. moles

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
