In a titration experiment, it was found that 25.0 cm3 of aqueous sodium hydroxide of an unknown concentration required 13.80 cm3 of 1.00 mol/dm3 dilute sulfuric acid for complete neutralization. Determine the concentration of aqueous sodium hydroxide in mol/dm3 and in g/dm3.

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
