0.436 g of an unknown diprotic acid is dissolved in about 60 ml of water in a beaker. the solution is transferred to a 100.00 ml beaker. 25.00 ml of this solution is then transferred to an erlenmeyer flask for the titration. what mass of the diprotic acid is in the 25.00 ml that is transferred?

Consider this initial-rate data at a certain temperature for the reaction described by

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
