Those guys & These guys

1) The class data for the vinegar and Baking soda showed that more gas should have been produced. This could have occurred because there was error in weighing the beaker when the reaction had not completely settled leaving air bubbles that had not yet released gas.

2) This relates to the balanced equation, which means that a formula must be equally proportionate on both sides, because the slope, rise over run, should be the same or somewhat similar as the ideal relationship. The balanced equation had given the ideal mass relationship because it tells us that there must be the same amount of gas produced in the product as their was in the initial maso or reactant.

3) Moles should have the same ratio in order to have a reaction. Just like an equation should be balanced.
