Calculate the equilibrium partial pressure of NO2 and N2O4.

how precipitation helps in extracting magnesium from sea water

2. A closed vessel of volume 10.0 L initially contains 1.303 g of water and no water vapor. Please calculate the mass of liquid water remaining once the system reaches equilibrium at 30 degrees Celsius. The vapor pressure of water at that temperature is equal to 0.0418 atm.

2.) The Haber-Bosch Process is used to synthesize ammonia. The reaction is as follows: N2 (g) + 3H2(g) = 2NH3(g). Using Le Chatelier's Principle, explain two ways to increase the yield of ammonia in this reaction.

Discuss the nature of bonds in NaCl and diamond. What do you mean by directionality of covalent bonds? Why materials with covalent bonds are brittle?

The molecular weight of sperm whale myoglobin is 17.8 kDa.17.8 kDa. The myoglobin content of sperm whale muscle is about 80 g · kg−1.80 g · kg−1. In contrast, the myoglobin content of some human muscles is about 8 g · kg−1.8 g · kg−1. Compare the amounts of O2O2 bound to myoglobin in human muscle and in sperm whale muscle. Assume that the myoglobin is saturated with O2,O2, and that the molecular weights of human and sperm whale myoglobin are the same. How much O2O2 is bound to myoglobin in human muscle? How much O2O2 is bound to myoglobin in whale muscle? The amount of oxygen dissolved in tissue water at 37°C37°C is about 3.5×10−5 M.3.5×10−5 M. What is the ratio of myoglobin‑bound oxygen to dissolved oxygen in the tissue water of sperm whale muscle?

Silicon carbide (SiC) is made by the high-temperature reaction of silica sand (quartz) with coke; the byproduct is carbon monoxide.(a) Write a balanced chemical equation for this reaction.(b) Calculate the standard enthalpy change per mole of SiC produced.(c) Predict (qualitatively) the following physical properties of silicon carbide:         conductivity, melting point, and hardness.

Great Lakes Chemical Company produces bromine, Br2, from bromide salts, such as NaBr, in Arkansas brine by treating the brine with chlorine gas. Write a balanced equation for the reaction of NaBr with Cl2. (Include states-of-matter under the given conditions in your answer. Use the lowest possible whole number coefficients.)
