Question

Write a balance equation using the correct formulas and including conditions (s, l, g, or aq) for each of the following reactions: a) solid calcium carbonate decomposes to produce solid calcium oxide and carbon dioxide gas. b) Nitrogen oxide gas reacts with carbon monoxide gas to produce nitrogen gas and carbon dioxide gas. c) Iron metal reacts with solid sulfur to produce solid iron(III) sulfide. d) Solid calcium reacts with nitrogen gas to produce solid calcium nitride. e) In the Apollo lunar module, hydrazine gas, N2H4, reacvts with dinitrogen tetroxide gas to produce gaseous nitrogen and water vapor.

Explanation / Answer

a) CaCO3 (s) = CaO (s) + CO2(g) b) N2O (g)+ CO (g) = CO2 (g) + N2(g) c) 2Fe(s) + 3S(s)---> Fe2S3(s) d) Ca (s) + N2(g) = Ca(NO3)2(s) e) 2 N2H4 (g) + N2O4 (g)-> 3 N2 (g)+ 4 H2O(l)
