Answer:

Option b) Carbon dioxide and oxygen

Explanation:

Thinking process:

Sodium hydroxide is an alkaline solid substance. It reacts with acids to form salts and water. In this case, it is known that carbon dioxide, CO₂, is an acidic gas. Therefore, the reaction gives a salt that results in carbon dioxide being absorbed by the sodium hydroxide.

Heated copper is an excellent removal of oxygen. This is because monovalent copper, Cu, has a deep binding affinity for oxygen. Hence the the oxygen trapped by the atom.

If 2.0 ml of 6.0m hcl is used to make a 500.0-ml aqueous solution, what is the molarity of the dilute solution?

svp [43]

Make sure that you understand what they are asking you from this question, as it can be confusing, but the solution is quite simple. They are stating that they want you to calculate the final concentration of 6.0M HCl once a dilution has been made from 2.0 mL to 500.0 mL. They have given us three values, the initial concentration, initial volume and the final volume. So, we are able to employ the following equation:

C1V1 = C2V2
(6.0M)(2.0mL) = C2(500.0mL)
Therefore, the final concentration, C2 = 0.024M.
