Acetylene gas (C2H2) is produced as a result of the reaction CaC2(s)+2H2O(l)-> C2H2(g)+Ca(HO)2(aq) if 13g of CaC2 are consumed in this reaction, how much H2O is needed?
Suppose that each sphere represents 6.7×1021 molecules and that the volume of the container is 1.0 L. What is the rate constant for the reaction in the usual units?
how does its vapor pressure change over time? It continues to steadily increase. It increases at first, then remains constant
Total pressure in kPa 10 seconds after initiation of the reaction if initially there was 88.3kPa of pure N 2 O 5 vapor Enter the total pressure in kPa 10 minutes after initiation of the reaction.
