Provide balanced formulae equations for each of the following observations:
d) calcium carbonate reacts with nitric acid solution - effervescence occurs
e) brown fumes of nitrogen dioxide gas reacts with water - universal indicator turns red
f) iron is 'corroded' by dilute sulfuric acid solution

d) Calcium carbonate + nitric acid = Calcium nitrate + water + carbon dioxide.
CaCO3 (s) + 2HNO3 (aq) ------> Ca(NO3)2 (aq) + H2O (l) + CO2 (g)
e) Nitrogen Dioxide + Water = Nitric acid
NO2(g) + H2O (l) ---------> HNO3(aq)
f) Iron + sulphuric acid = Iron Sulphate + hydrogen
2Fe(s) + 3H2SO4 (aq) -----------> Fe2(SO4)3 (aq) + 3H2 (g)

I don't understabd what ur asking but according to what I can tell, u r trying to combine 2 chemical substances to get an equation of of a result in which u want to see what happens when each substance is combined. Well, (c.c) Calcium Carbonate is a nono with nitric acid solution, this is because it is used as an antibiotic against it.
