A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water.
The paths in which electrons travel are called orbitals.
It has to be understood that 2 moles of oxygen are there in each mole of PbO2. Then it has to be calculated for 2 moles of oxygen.
Amount of oxygen = 2 * 5.43 moles
= 10.86 moles
Now it is also a fact that each mole of H2O contains 1 mole of oxygen. Then it can be easily concluded that 10.86 moles of water will be produced. I hope the procedure is clear enough for you to understand.
Reactants + Energy → Products
I guess this is the answer
You’re welcome ;)
