Three manufacturers are producing carbonated bottled water. One company introduces carbonate by bubbling carbon dioxide into water until CT=10-3 M (equivalent to adding "H2CO3*" until CT = 1 x 10-3 M), a second adds sodium bicarbonate (NaHCO3) until CT = 10-3 M, and a third adds sodium carbonate until CT=10-3 M. ("CT" is the total concentration of all carbonate species, i.e., [H2CO3*], [HCO3-], and [CO32-].) Estimate the pH of the bottled water from each of the three manufacturers.
Calcium cyanamide, CaCN2, reacts with water to form calcium carbonate and ammonia; CaCN2(s)+3H2O(l)-->CaCO3(s)+2NH3(g). a) How many grams of water are needed to react with 75.0 g of CaCN2
Suppose that you were to fill a 1L beaker with only 200 mL of water and it is not deep enough to make the water level inside and outside the graduated cylinder the same.
