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()

How many total moles of ions are present in 0.0158 mol of nacl?

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night.  when he took it out, its new volume was 322 milliliters, but its pressure was the same.  if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is  kelvins.
