Transcript of Chemical Equations Test Review. Diatomic Molecules 1. List the seven diatomic molecules.
Labeling of equationFe(s) + CuSO4(aq) → Fe2(So4)3(aq) + Cu(s)
reactantsyields products
2. Label the parts.
(a) What is meant by the symbol in parentheses following a chemical formula? State of matter
(i) (s) Solid
(ii) (l) Liquid(iii) (g) Gas(iv) (aq) aqueous – dissolved in water
3. Classify the reaction
(a) 2NaCl (aq) + Pb(NO3)2(aq) → PBCL2(s) + 2Na(NO3)(aq)
(b) H2(g) + Cl2(g) → 2HCl(g)
(c) C2H8(g) + 4O2(g) →2CO2(g) + 4H2O(g)
(d) 2Li(s) + 2H2O (l ) → 2LiOH(aq) + H2(g)
(e) 2KNO3(s) → 2KNO2(s) + O2(g)

4. Add coefficients
to balance the equations
(a) ____Hf + ____N2 → ____Hf3N4
(b) ____Mg + ____H2 SO4 → ____ MgSO4 + ____H2
(c) ____C2H6 + ____ O2 → ____ CO2 + ____ H2O
(d) ____Pb(NO3)2 + ____NaI → ____PbI2 + ____NaNO3
(e) ____Pb(NO3)2 → ____PbO + ____NO2 + ____O2
