Which of the following would result in the magnesium ribbon 'dissappearing' in less than 45 seconds? *Warming the acid
*Using 2g magnesium ribbon
*Stirring the mixture
*Adding water to the acid

BTW:- The acid is sulfuric acid

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
