Question

describe in words the electron transfer(s) that takes place in this equation
2PbS + 3O2 ----> 2PbO + 2SO2

Answer 1

balanced equation :

2 PbS + 3 O2 = 2 PbO + 2 SO2

all you have to do is make sure the number of each element in the reactant are the same as the number of elements in the product

for example the reactant (left side of equation) had O2 , while the product had O and O2, which equals to three O. Just play with the numbers and balance both sides.
