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.

Yanka [14]

Answer:

its 0.163 g

Explanation:

From the total pressure and the vapour pressure of water we can calculate the partial pressure of O2​

PO 2 =P t −P H 2 O

​= 760 − 22.4

=  737.6 mmHg

From the ideal gas equation we write.

W= RT/PVM = (0.0821Latm/Kmol)(273+24)K(0.974atm)(0.128L)(32.0g/mol/) =0.163g
