Place the clay triangle on top of the ring support and place the crucible containing the baking soda on top of the clay triangle. The lid should be til 4. Heat the crucible and its contents with the bunsen burner for 10 minutes.
Write a balanced equation for the decomposition of the sodium bicarbonate The from SCIENCE CP at Woodmont High.

Mole Relationships and the Balanced Equation. Introduction. A simple decomposition reaction of sodium bicarbonate (baking soda) presents the opportunity for students to test their knowledge of stoichiometry, factoring labels, and the mole concept. This outcome-based lab requires the students to pre- cisely predict the mass of the solid product.
The Reaction. Since this particular laboratory is not equipped to work with chemicals as toxic as sodium azide, we will work with the similar gas producing agent sodium bicarbonate (NaHCO 3). When sodium bicarbonate is allowed to react with acetic acid (CH 3 COOH) carbon dioxide (CO 2) and two other products are formed as shown below.
And, since the second equation that resulted in 1.89 g of sodium carbonate is closer to the actual mass of 1.8 g we measured, the second equation would best represent the thermal decomposition of sodium bicarbonate.
Write the name and formula of the gas in the space provided. Write a balanced chemical equation for this double-replacement reaction. One of the two products of this reaction is carbonic acid (H 2 CO 3 ), which immediately forms water and the gas you identified after exposure to the flaming and glowing splints.
