final review slide 4

How does Lavelle find that there is deltan=1 mole of gas when there's 3 moles of gas on the right side of the equation?

Re: final review slide 4

he finds the net production of gas because there are 3 mols of gas on the right side (products), 2 mols of gas on the left (reactants). Because this is a standard 1.00 mole reaction of O2, meaning the equation presented is what is occurring, you find the total production with a 3-2=1 mole of gas. the change in the amount of gas is +1 mole from reactants to products.

edit whoops i just saw your new message!

Re: final review slide 4

You subtract the mol of gas formed and the mol of gas reacting
