									  How does Sodium hydro-carbonate react?
Material:
Crucible with cover
Scales
Bunsen burner

Chemicals
Solid sodium hydro-carbonate, NaHCO3(s)


When sodium hydro-carbonate, NaHCO3(s), is heated it decompose. The decomposition can
theoretically occur in three different ways:

NaHCO3(s)  NaOH(s) + CO2(g)
2NaHCO3(s)  Na2O(s) + H2O(g) + 2CO2(g)
2NaHCO3(s)  Na2CO3(s) + H2O(g) + CO2(g)

Your task is to design an experiment with the above given equipment and chemicals.
Take 2.00-3.00 grams of the salt and heat it.

With the experiment you shall determine which of the above presented equations is correct
and present the result in a lab report.
The lab report should include: materials, method, collected data, data analysis, evaluation
