Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric acid with manganese(IV) oxide:
4HCL(aq) + MnO2(s) ----> MnCl2(aq) + 2H2O(l) + Cl2(g)
You add 42.5 g of MnO2 to a solution containing 47.7 g of HCl.
(a) What is the limiting reactant? MnO2 or HCL?
(b)What is the theortical yield of CO2?
(c) If the yield of the reaction is 79.9%, what is the actual yield of chlorine?
what is the maximum kinetic energy of a photo electron ejected from cesium by 555nm light? note that if the wavelength of the light used to irradiate the cesium surface become longer than 600 nm, no photoelectrons are emitted.
Identify and discuss three key features associated with the combustion of polymeric materials or compounds that are relevant to the safety and health of an EH&S or a FS professional responding
Treatment with cyanogen bromide, which cleaves at M, resulted in two fragments: a pentapeptide containing two K residues and a tripeptide containing V, G, and A. (The residues are not listed in any particular order.)
Find the ?H for the reaction below, given the following reactions and subsequent ?H values: Zn(s) + 1/8S8(s) + 2O2(g) ? ZnSO4(s) Zn(s) + 1/8S8(s) ? ZnS(s)
