Stoichiometry explained in this solution
If the yield of CO2 (g) from the reaction of butane with hydrogen peroxide is only 80.65%, with how many grams of butane and hydrogen peroxide must you have started if you obtain 26.45 g of CO2 ?
Nickel(II) carbonate is placed into an open container and heated. A given amount of nickel(II) oxide is produced. However, if the same amount of nickel(II) carbonate is placed into a sealed container and heated to the same temperature as previously, less nickel(II) oxide is produced. How do you explain this? Be sure to give a fully justify your answer
