From the balanced molecular equations, write the complete ionic and net ionic equations for the following: a. K2C2O4(aq)+Ba(OH)2(aq)⟶2KOH(aq)+BaC 2O4(s)
b. Pb(NO3)2(aq)+H2SO4(aq)⟶PbSO4(s)+2HN O3(aq)
c. CaCO3(s)+H2SO4(aq)⟶CaSO4(s)+CO2(g)+ H2O()

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
