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.
The sandstone is older.in order for the granite to have been formed with sandstone in its precnese then it had to have already exsisted in that area..making it older.
This is primarily due to the large increase in the volume that the gas molecules themselves occupy.
<h3>How is the ideal gas equation defined?</h3>
The ideal gas equation is PV = nRT. P represents for the ideal gas's pressure, V for its volume, n for its total mass, expressed in moles, R for its gas constant, and T for temperature in this equation.
<h3>the author of the ideal gas equation?</h3>
The pressure, volume, heat, and quantity of an ideal gas are all related by a single equation that was created through the experimental work of multiple people, including Robert Boyle, Pierre A. C. Charles, and Joseph Gay-Lussac. Boyle's Law states that as pressure decreases, gas volume increases.

Answer:
B. Sill
Explanation:
Magma that squeezes between horizontal rock layers hardens to form a sill. A dome mountain forms when uplift pushes a large body of hardened magma toward the surface, which eventually becomes exposed.
