2. Calcium carbonate, when heated strongly in an open test tube, decomposes to yield both the corresponding metal oxide, and a non-metal oxide. The non-metal oxide is a gas, and escapes into the atmosphere. In such a reaction, the following data are collected. Mass of calcium carbonate and test tube before heating 30.46 g Mass of the test tube and contents after heating 27.86 g Mass of empty test tube (a) What type of reaction is this? (b) Write a balanced chemical equation to summarize the reaction. (c) Use the data to illustrate that matter has been conserved, and that to justify the equation that you have written in (b).

Dinitrogen monoxide, N2O, reacts with propane, C3H8, to farm nitrogen, N2; carbon dioxide. CO2; and water, H2O. Write a balanced chemical equation for this reaction, treating all substances as gases. Include phases in your equation. Two reservoirs, separated by a closed valve (of negligible volume), are filled with the reactants (one on each side). The pressure of N2Ois measured to be 1.4atm. The pressure of C3H8is measured to be 1.2atm.
