Solution
Direct combination: “Is a reaction in which two elements or compound combine to give one new compound.”
\[\ce{C + O2->CO2}\]
Decomposition reaction: “A chemical compound (breaks up) decomposes into two or more simpler substances.”
\[\ce{Copper carbonate->Copper oxide + Carbon dioxide}\]
\[\ce{CuCO3->CuO + CO2}\]

Why is the amount of gas collected in one of the test tubes in the following Activity double of the amount collected in the other? Name this gas.
- Take a plastic mug. Drill two holes at its base and fit rubber stoppers in these holes. Insert carbon electrodes in these rubber stoppers as shown in the following Fig.
- Connect these electrodes to a 6 volt battery.

A solid substance P which is very hard is used in the construction of many buildings, especially flooring. When substance P is heated strongly, it decomposes to form another solid Q and a gas R is given out. Solid Q reacts with water with the release of a lot of heat to form a substance S. When gas R is passed into a clear solution of substance S, then a white precipitate of substance T is formed. The substance T has the same chemical composition as starting substance P.
