01. We observed the following reaction in the Reaction in a Bag activity:
CaCl, (aq) + 2NaHCO, (aq) + phenol red (basic form) -
Caco, (s) + 2NaCl (aq) + H20 (aq) + CO2 (aq) + phenol red (acidic form)
What are the reagent(s) in this reaction?
What are the product(s) in this reaction?

Answer explain why it is not possible to deduce a complete order of reactivity.

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
