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).

Transcribed Image Text: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

(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).
Expert Solution
Step 1
Given data,
Mass of CaCO3 and test tube before heating = 30.46 g
Mass of contents and test tube after heating = 27.86 g
Mass of vacant test tube = 24.56 g
