Question: Describe the Chromatography process and the different azo dyes used.
The exothermic chemical reaction CO(g) + H2O(g) CO2(g) + H2(g) has Kc = 0.034 at 25°C. We currently have a flask containing all the components listed in this equation at equilibrium at 25°C. Subsequently, we will either (1) add some H2 to the flas..
the solubility of the k3fec2o43.3h2o product at 00c is 4.7 g per 100 g water. given this calculate the maximum percent
Evaluate the z-component of the angular momentum and the kinetic energy of a particle on a ring that is described by the (unnormalized) wavefunctions e^iΦ ,e^-2iΦ ,cosΦ ,(cosφ)e^iΦ , (sinφ)e^-iΦ
1 mole of a hydrocarbon of formula CnH2n was burned completely in oxygen producing carbon dioxide and water vapour only. It required 192 g of oxygen. Work out the formula of the hydrocarbon.
Question- In an experiment involving the reaction of methane and hydrogen sulfide, 1.00 mol of CH4, 2.00 mol of H2S, 1.00 mol of CS2, and 2.00 mol of H2 are mixed in a 250. mL sealed flask and react at 960. Degree C. At this temperature, K c = 0.0..
The enzyme catalase catalyzes the decomposition of hydrogen peroxide. The following data are obtained regarding the rate of reaction as a function of substrate concentration.
The lead contained in a 0.2000 g sample is precipitated as PbCrO4. The precipitate is filtrated, washed and re-dissolved in acid to give lead ions and dichromate.
