In the test for carbonate, two gases are generated: CO2 (g) and H2 (g). Of the two, CO2 (g) is more dense than air, while H2 is much less dense than air. What do you think the purpose of generating H2 (g) is in the 10 mL beaker?

Step 1
The generation of CO2 (g) and H2 (g) suggests that a carbonate is reacting with an acid, leading to the release of these gases. Show more…

Lets say you were doing an experiment on two different chemicals in two different test tubes. One chemical is giving off oxygen gas or hydrogen gas the other is giving off carbon dioxide gas. What one test could you do in each test tube that would prove which is giving of the oxygen or hydrogen an which is giving off the carbon dioxide

Which of the following will you use in this lab to generate carbon dioxide gas? a) sodium carbonate b) sodium bicarbonate c) calcium carbonate d) aluminum hydroxide 2. If the R in the Ideal Gas Law is 0.0821, which of the following are units that can be used for the variables in the equation? Select all that apply. a) liter b) degrees C c) mole d) mm Hg 3. To determine the volume of gas collected, you will a) measure the water remaining in the flask b) empty the flask and refill it c) measure how much it takes to bring the flask back to full d) none of the above 4. If the partial pressure of water at 25 degrees is 23.8 mm Hg and the total pressure is 776 mm Hg, what is the partial pressure of carbon dioxide collected over water at 25 degrees? Put answer in one decimal place and omit units.
