Answer:
It is a group of compound derived from alkanes containing one or more halogens .
Answer:
The correct answer is 40.7 grams.
Explanation:
Based on the given information, the volume of copper sulfate added to the solution is 255 ml or 0.255 L. The molarity of copper sulfate is not given, so let us consider it to be 1 M, which can also be written as 1 moles per liter.
The moles of copper sulfate can be determined by using the formula,
Moles = Molarity * Volume in Liters
Moles of CuSO4 = 1 moles/Liter * 0.255 L
Moles of CuSO4 = 0.255 moles
The mass of CuSO4 added in the solution will be,
Mass of CuSO4 = Moles * Molecular mass
= 0.255 moles * 159.609 grams per mole
= 40.7 grams.
Wear gloves when handling chemicals.
Make sure that none of the liquids near the Bunsen burner are flammable.
Explanation:
The safety precautions the student must apply while completing his experiment is that he/she must wear gloves while handling the chemicals and they must make sure that none of the liquids near the Bunsen burner are flammable.
- Safety guidelines provides a detailed and careful way to carry out experiment and observations in the laboratory.
- This is all in a bid to accidents in the workspace.
- It is a good practices to wear gloves and laboratory coat while handling chemicals.
- Also make sure to put out the Bunsen burner when not in use.
- Keep papers and books away from the work area. Chemicals and papers are not friends.
- Ensure that flammable liquids are not close to the Burner.
