Carbonates and bicarbonates: Take about 1g of solid carbonate/ bicarbonate in to a boiling tube and fi x a stopper carrying a delivery tube.

Insert the free end of the delivery tube into about ½ cm height of limewater

in a test tube. Heat the boiling tube. Record any gas evolving and a change in

color of limewater inside the test tube. Note relative time taken to evolve gas. Na2CO3

Why does his teacher ask him to balance the equation by including the correct coefficient

Astudent states that 9.0 g of baking soda will form an unsaturated solution in 100 g of water. what do you need to know to decide whether this statement is correct? a. the temperature of the water and the molar mass of baking soda b. the percent by volume of the solution and the solubility of baking soda c. the temperature of the water and the solubility of baking soda at that temperature

When an experimenter draws a conclusion that he assumes will apply to all situations set up similarly to his test situation, even though he cannot possibly have examined all possible test scenarios, the experimenter is using deductive reasoning inductive reasoning abductive reasoning subjective reasoning
