Astudent is heating a chemical in a beaker with a bunsen burner.
in a paragraph of at least 150 words, identify the safety equipment that should be used and the purpose of it for the given scenario.

The student should wear a lab coat that will protect the body from potential spilling of the substance, protective eyewear in case the compound will explode and latex gloves to have some protection against the chemicals which may burn the skin.  

Besides the respiratory mask, the heating should be carried out in a laboratory hood to prevent the inhalation of the toxic compound which may be released if the chemical will burn.

After the heating is complete the beaker should be handled with  wooden pliers because is very hot and so avoiding thermal burning.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
