At elevated temperatures, NaHCO3 is converted quantitatively to NazCO3: 2 NaHCO:(s) → NazCO3 (s) + CO2 (g) + H20 (g). Ignition of a 0.6239-g sample of an antacid tablet containing NaHCO3 and nonvolatile impurities yielded a residue weighing 0.4129 g. Calculate the percent purity of the antacid sample. Some helpful FW: NaHCO3 = 84.01 ; Na2C03 = 105.99 ; CO2 = 44.01 ; H2O = 18.02

Chlorine atoms contribute to the destruction of the Earths ozone layer by the following sequence of reactions: Cl + O3 ClO + O2 ClO + O Cl + O2 where the O atoms in the second step come from the decomposition of ozone by sunlight: O3(g) O(g) + O2(g) What is the net equation on summing these three equations? Why does this lead to ozone loss in the stratosphere? What is the role played by Cl in this sequence of reactions? What name is given to species such as ClO?
Possible death for animals and human being is expected for 430 ppm of chlorine gas exposure in 30 minutes. Cl2 released from MGPI approximately 45 minutes. Determine the probable death percentage from this toxic release accident.

Phosphate buffered saline (PBS) is a very common reagent in cell biology labs that do cell culture since is it osmotically stable for most eukaryotic cells. It is often prepared as 10X PBS (10.5 mM KH2PO4, 1.552 M NaCl, 29.7 mM Na2HPO4) to save on shelf space. How would you prepare 1 L of 10X PBS given 1M KH2PO4, NaCl (FW 58.44), 906mM Na2HPO4? a. What do you know about the forms of thechemicals you are given to prepare the 10X PBS and how do you know this? What should the final units for each of the 3 components be in your answer? What is the solvent for 10X PBS and how do you know this?

How many g of water you need to add into HCl solution (V= 130.0 cm3 mass percentage 22.0 % (w/w), density: 1.40 g/cm3) if you would like to get a solution with 5 % (w/w)? What is the concentrations (g/dm3 and mol/dm3) of the final solution if the density of it is 1.050 g/cm3? Mr(HCl) = 36.46.
In 1995, Mario Molina, Paul Crutzen, and F. SherwoodRowland shared the Nobel Prize in chemistry for their work onatmospheric chemistry. One of several reaction sequences pro-posed for the role of chlorine in the decomposition of strato-spheric ozone is (1) Cl(g) +O3(g)→ ClO(g) +O₂(g) (2) ClO(g) +ClO(g)→ Cl₂O₂(g) (3) Cl₂O₂→ (g)2Cl(g)+ O₂(g).Over the tropics, O atoms are more common in the stratosphere:(4) ClO(g) +O(g)→ Cl(g) +O₂(g).(a) Which, if any, of these are oxidation-reduction reactions?(b) Write an overall equation combining reactions 1–3
Consider a mixture of the two solids, BaCl2 ∙ 2H2O (FM 244.26) and KCl (FM 74.551). When the mixture is heated to 160°C for 1 h, the water of crystallization is driven off: BaCl2 ∙ 2H2O(s) BaCl2(s) + 2H2O(g) A sample originally weighing 1.7839 g weighed 1.5623 g after heating. Calculate wt% Ba, K, and Cl in the original sample. (Hint: The mass loss tells how much water was lost, which tells how much BaCl2 ∙ 2H2O was present. The remainder of the sample is KCl.)
