The combustion of ethane (C2H6) produces carbon dioxide and steam. 2C, H, (g) + 702(g) — 4CO2(g) + 6H2O(g)
How many moles of Co, are produced when 5.55 mol of ethane is burned in an excess of oxygen?
moles of CO2:

Number of moles of CO₂ produced = 11.1 mol

Explanation:

Given data:

Mass of ethane = 5.55 mol

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

2C₂H₆ + 7O₂       →     4CO₂ + 6H₂O

Now we will compare the moles of ethane and carbondioxide.

             C₂H₆          :           CO₂

                 2             :            4

              5.55          :         4/2×5.55 = 11.1 moles

Number of moles of CO₂ produced =  11.1 mol

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry
