Explain how the Law of Conservation of Mass is applied in the balanced equation illustrated below. 2Na(s) + 2 H2O(l) to form 2 NaOH(aq) + 1 H2(g) please help, I need to turn it in right now!! DO NOT SEND ANY VIRUSES OR I WILL REPORT YOU

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

Based on the equation, how many grams of br2 are required to react completely with 29.2 grams of alcl3? alcl3 + br2 → albr3 + cl2 48.7 grams 52.6 grams 56.7 grams 61.3 grams
