If concentrated sulfuric acid is spilled during the experiment, what is the proper procedure for cleaning the spill?

Sulfuric acid (H2SO4) is a strong acid which should be neutralized with a base. Ideally, sodium bicarbonate (NaHCO3) is used to treat acid spills. The reaction is as follows:

H2SO4 + 2NaHCO3 → Na2SO4 + 2H2O + 2CO2

Bubbles will be formed as CO2 is released. Once all H2SO4 has been neutralized the bubbles will stop. The pH of the spill after neutralization can be checked with a pH and should be between 6-9. If optimal pH is observed the waste can be disposed into a proper container and the work station can be cleaned with a paper towel.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
