The equation for the complete combustion of ethene (C2H4) is
C2H4(g) + 3O2(g) = 2CO2(g) + 2H2O(g)
If 2.70 mol C2H4 reacts with 6.30 mole of O2, what is the limiting reactant?

Balance the following chemical equation
N2 + O2 → N2O5
When balancing chemical equations, we change the coefficients (the numbers in front of each chemical formula in an equation) so that the total number of atoms of the products are the same as the reactants.

I made flammable snow for Christmas!
⚠️Don't try this at home!⚠️
This is my last video of 2023, and I'm going to take a break until the New Year.
Thanks for a great year everyone!!
Sodium polyacrylate and alcohol make a pretty convincing fake snow that's also extremely flammable!
