Consider the reaction 2 SO2(g) + O2(g) <=> 2 SO3(g), which is exothermic as written. What would be the effect on the equilibrium position of adding SO2(g)? 1. Reaction would go to the left, making more "products" 2. Reaction would go to the right, making more "products" 3. No change on the equilibrium position 4. Reaction would go to the right, making more "reactants" 5. Reaction would go to the left, making more "reactants"
pH = log[H3O+] , pH + pOH = 14, [H3O+] * [OH-] = 1.0 X 10^-14, pH = -log(0.001) = 3 Could you show me a few of the steps between line one and two in both of these conclusions?
What is the molality of CrCl3 in a solution prepared by dissolving 75.2 g chromium(III) chloride hexahydrate in 250.0 g of water.
Hydrogen phosphate buffer, Buffer solutions have the unique ability to resist changes in PH when an acid or base is added to them. One important buffer system that helps to maintain blood pH at a constant value of 7.4 is the hydrogen phosphate buf..
The molar extinction coefficient of benzene equals 100 M-1cm-1 at 260 nm. Assume this number is independent of solvent. (a) What concentration would give an absorbance of 1.0 in a 1 cm cell at 260 nm?
Compare the volume of 1.0 g of bromine, Br2, as a solid, liquid, and gas. The density of solid bromine just below the melting point of -7°C is 3.2 g/mL, of liquid bromine at 25°C is 3.1 g/mL.
You are testing some novel fuel mixtures for potential use in automobiles. Your testing apparatus is a 2.54-cm inner diameter cylinder fitted with a piston, designed to mimic a cylinder found in a car engine.
The density of germanium is 5.325 g/cm3. If you made a 5.3-nm diameter quantum dot of germanium, how many Ge atoms would it contain? Assume the dot is spherical.
A hypothetical atom has four allowed energy levels. As shown in the accompanying diagram, the emission spectrum of this atom will contain six transitions, labelled A - F.
