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
The average pH of precipitation in rural areas is 5.80. Assuming that the pH is controlled by the carbonate system, i.e., no anthropogenic acid gases are present in the atmosphere.
