Why is it that when I have a very small amount of acetylene in a test tube and have a small flame by it so oxygen will react with it, there is a popping sound.
This is complete combustion

The products are CO2 and H2O

You have answered your own question. Acetylene is flammable, just as hydrogen is. Small amounts in test tubes ignite with whistling sounds.

2C2H2 + 5O2 ---> 4CO2 + 2H2O a million. utilising the molecular weight of O2, calculate the form of moles of O2 you have. 2. The stability equation tells you that 2 moles of C2H2 react with 5 moles of O2; calculate the form of moles of C2H2 that react with the form of moles of O2 you have. 3. utilising the molecular weight of C2H2, calculate the mass of this many moles of C2H2.
