Question
Chapter 1, Problem 1Q
Interpretation Introduction
Interpretation:
The five safety features that are found in the laboratory should be determined.
Concept introduction:
Lab safety is of paramount importance. Lab equipment and chemicals like acids that are handled improperly can cause serve injuries and even death and therefore, for emergency or the accidentally time certain some safety equipment should be present in the laboratory
Expert Solution & Answer
Explanation of Solution
The five safety features of the laboratory are as follows:
- Fire extinguisher: A portable device which discharges a jet of foam, water, gas, or other material to extinguish a fire.
- First aid kit: A bag or case that contains basic medical supplies is designed to be used when someone is injured.
- Chemical fume hoods: A chemical and fire-resistant enclose with a movable window at the front allows the user access to the interior that is a safe zone.
- Fire blankets: Fire blanketsare used to smoother a fire that involves someone's clothes.
- Safety showers: It dumps a huge amount of water in a short period of time and a very effective method in case when a person's clothes are ablaze.

An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)
