Complete the reaction equations. Indicate the type of each reaction in terms of all classifications known to you: a) barium chloride solution + sodium sulfate solution; b) calcining zinc carbonate; c) zinc + hydrochloric acid; d) iron + chlorine; e) methane + bromine; f) isomerization of butane.

1. The reaction between barium chloride and sodium sulfate is an exchange reaction, not redox (not ORP), irreversible, non-catalytic.

BaCl2 + Na2 SO4 = BaSO4 + 2 NaCl. Barium sulfate precipitates.

2. The reaction of decomposition of zinc carbonate, not ORP, irreversible.

ZnCO3 = ZnO + CO2.

3. Reaction according to the number of initial substances and reaction products – decomposition reaction. Not OVR, irreversible.

Zn + 2HCl = ZnCl2 + H2.

4. Reaction according to the number of starting substances and reaction products – the reaction of the compound, ORP.

2Fe + 3Cl2 = 2FeCl3.

5. Reaction of substitution, OVR.

CH4 + Br2 = CH3Br + HBr.

6. Reaction of isomerization. Catalytic.

Butane is converted to isobutane, or 2-methylpropane.

H3C- CH2 –CH2 –CH3 AlCl3 CH3 –CH- (CH3) – CH3 (2 –methylpropane).
