Homework Statement
I'm currently doing a grade 11 chemistry lab online...So, there's three reactions that we have to interpret...
1. CH4 + 2 O2 ---> CO2 + 2 H2O
2. 2 C2H6 + 7 O2 ---> 4 CO2 + 6 H2O
3. C3H8 + 5 O2 ---> 3 CO2 + 4 H2O
Now, when I add the theoretical masses of the products for the first reaction (I'll spare the math for now), they add up to mass of the actual masses of the products in the first reaction. However, when I sum the theoretical masses of the products in the second reaction, I don't get the same sum as the actual masses in the second or third reaction. I notice that the actual masses for all three reactions (methane, ethane, and propane) are exactly the same. Is this just because the mass loss in the actual reactions are attributed to waste products and heat, or am I doing something terribly incorrect? Or is there something wrong with my simulation.
PS - I can provide my math, but I feel as though the program is working fine and that it's just that all hydrocarbon reactions of this sort yield the same product mass no matter what.
