Question

The reaction of phosphine with oxygen has the following unbalanced
equation

PH₃ + O₂ → P₄O₁₀ + H₂O

The coefficient for oxygen in the balanced equation is...

Hint: Balance the reaction on a sheet of scratch paper before attempting to answer this question.

Answer 1

Answer #1

First of all balance phosphorus by multiplying 4 with PH₃

4PH₃ + O₂ ------> P₄O₁₀ + H₂O

Now balance hydrogen by multiplying 6 with H₂O

4PH3 + O2 ------> P4O10 + 6H2O

Now balance Oxygen by multiplying 8 with O2

4PH₃ + 8O₂ -------> P₄O₁₀ + 6H₂O

the coefficient for oxygen in the balanced equation is 8

Acetylene gas produced in the experiment in question #2 is the gas used in welding torches. Recall its formula is two carbons and two hydrogens. You could take the balloon full of acetylene from question #2 and tie it to the end of a meter stick. Then if you hold the balloon near a burner flame, the balloon will explode as the oxygen from the air (O2) combines with the acetylene (two carbons and two hydrogens). The exothermic reaction produces...
