2 H2O2 2H2O + O2 V O2 = 63 mL, P=1.008 atm, T=294 K, R=0.0831
amount of 2H2O2 in experiment was 5mL
1. using ideal gas law, n = PV/RT find moles of O2.
2. Find theoretical moles of O2
3. Using actual moles and theoretical moles calculate the percentage hydrogen peroxide in your experiment.

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
