The most common injuries in a chemistry lab is making a fire, heat burns, chemical burns, cuts and scrapes, contamination, inhalation, and spills and breaks.
1.) You can prevent making a fire by making sure you close and seal flammable materials.
2.) You can prevent heat burns by teaching the students how to properly use tongs,water baths, and other cooling equipment.
3.) You can prevent chemical burns by treating the chemicals with caution, measure carefully, and use the approved containers.
4.) You can prevent cuts and scrapes by telling the students how to use the blades safely, and also when they are disposing broken or sharp items they should know how to wrap them up so no one else will get hurt.
5.) You can prevent contamination by washing your hands, protect their clothing and skin with a lab coat or a lab apron, gloves and glasses, and cleaning your area where the germs of the chemicals were so no one will become.
6.) You can prevent inhalation by opening up windows, using ventilation fans, and using an equipment that measures the amount of gas emission in a room.
7.) Finally, you can prevent spills and breaks by telling the students what will happen if anything spills, and tell them to clean up.
Answer:
The vapor pressure at 60.21°C is 327 mmHg.
Explanation:
Given the vapor pressure of ethanol at 34.90°C is 102 mmHg.
We need to find vapor pressure at 60.21°C.
The Clausius-Clapeyron equation is often used to find the vapor pressure of pure liquid.
We have given in the question
And is the Universal Gas Constant.
Taking inverse log both side we get,
It gets hotter because the core is the outside of the eath and the mantel is the more inside/hope i helped
