Get started for freeTo study a marine organism, a biologist prepares a 1.00-kg sample to simulate the ion concentrations in seawater. She mixes 26.5 g of NaCl, 2.40 g of MgCl2, 3.35 g of MgSO4, 1.20 g of CaCl2, 1.05 g of KCl, 0.315 g of NaHCO3, and 0.098 g of NaBr in distilled water.
(a) If the density of the solution is 1.025 g/cm3, what is the molarity of each ion?
(b) What is the total molarity of alkali metal ions?
(c) What is the total molarity of alkaline earth metal ions?
(d) What is the total molarity of anions?
Identify the oxidizing agent and the reducing agent in the following reaction, and explain your answer:
Limestone (CaCO3) is used to remove acidic pollutants from smokestack flue gases. It is heated to form lime (CaO), which reacts with sulfur dioxide to form calcium sulfite. Assuming a 70.% yield in the overall reaction, what mass of limestone is required to remove all the sulfur dioxide formed by the combustion of 8.5104 kg of coal that is 0.33 mass % sulfur?
Give the oxidation number of carbon in the following:
Calcium dihydrogen phosphate, Ca(H2PO4)2, and sodium hydrogen carbonate, NaHCO3, are ingredients of baking powder that react with each other to produce CO2, which causes dough or batter to rise:
[unbalanced]
If the baking powder contains 31% NaHCO3and 35% Ca(H2PO4)2 by mass:
(a) How many moles of CO2 are produced from 1.00 g of baking powder?
(b) If 1 mol of CO2 occupies 37.0 L at 350_F (a typical baking temperature), what volume of CO2is produced from 1.00 g of baking powder?
