When ethane (C2H6) reacts with chlorine (Cl2) the main product is C2H5Cl; but other products containing Cl (chlorine), such as C2H4Cl2, are also obtained in small quantities. The formation of these other products reduces the yield of C2H5Cl. In a certain experiment 195 g of C2H6 reacts with 225 g of Cl2.
(a) Assuming that C2H6 and Cl2 react only to form C2H5Cl and HCl, calculate the theoretical yield of C2H5Cl.
(b) Calculate the percent yield of C2H5Cl if the reaction produced 180. g of C2H5Cl.
Cd2 forms two complexes with C2H3O2, with the following formation constants:(a) Find K2 for the reaction, (b) You prepare 1.00 L of solution containing 0.110 mol CH3CO2Na and 4.00 × 10-4 mol Cd(ClO4)2. Compute the fraction of cadmium in the form ..
Compound A, C9H12, undergoes nitration to give 3 products. The 1H NMR spectrum of A shows a complex three-proton multiplet at 6.92-6.99 ? and a nine-proton singlet at 2.34 ?
If 4.00 g of the unknown compound contained 0.133 mol of C and 0.267 mol of H, how many moles of oxygen, O, were in the sample?
how fast must a 144.1g baseball travel in order to have a de Broglie wavelength that is equal to that of an x-ray photon with = 73 pm?
Description of amino acids, Chiral compounds occur when a carbon atom has four different things bonded to it. All but the simplest amino acids (glycine) are chiral because the alpha carbon has an amine group
