Solution

The liquid that can be used to test for carbon dioxide is lime water. Here are the steps to perform the test:

  1. First, prepare a solution of lime water by dissolving calcium hydroxide in water.
  2. Then, bubble the gas you suspect to be carbon dioxide through the lime water.
  3. If the lime water turns milky or cloudy, then carbon dioxide is present. This is because carbon dioxide reacts with the calcium hydroxide in the lime water to form calcium carbonate, which is insoluble and appears as a milky suspension.
  4. If no change is observed, then carbon dioxide is not present in the tested gas.

Solid carbon dioxide is often referred to as dry ice. It is a substance that turns from the solid state into the gas state without becoming a liquid. What is the name of this process?

Carbon dioxide is often used in biomedical engineering labs for many applications, one of which is cell culturing. UltraSuperCell Services®is a large commercial laboratory, and requires large amounts of carbon dioxide. They have determined that it is much more efficient to pump this carbon dioxide from a neighbouring facility located 1000 m away via a long pipe with an internal diameter of 12 cm and a fanning friction factor of 0.005. The flow is isothermal at 25°C and carbon dioxide has the chemical formula CO2, where carbon has a molecular weight of 12g/mol and oxygen has a molecular weight of 16 g/mol. The neighbouring facility stores the carbon dioxide at a pressure 521 kPa and the lab requires the pressure to be 200 kPa. A. What is the mass flow rate of the carbon dioxide? Show all working.
