What equipment do chemists use?
Some chemists use a Bunsen burner to heat or expose an item to flame. They also use buret to measure liquid. Crucibles are for heating small quantities to very high temperatures. Erlenmeyer flask heat and store liquids. The advantage to this bottom is wider than the top. This makes it heat quicker because the greater surface area is expose to the heat. An Evaporating dish heats and evaporates liquids. The Florence flask heats substances that need to be heated evenly. The bottom allows heat to distribute through the liquid more evenly. Microspatulas commonly are called a spatula moves small amounts of solid from place to place. It’s like a stick. Mortar’s and pestles crush solids into powder. Plastic and disposable pipit move small amounts of liquid from place to place. When things are hot tongs help hold them. These items are the equipment most chemist use. [3]

Why do certain chemicals when mixed explode?
Certain chemicals explode when mixed because of their danger level. Some chemicals can’t be stored next to each other because if there is an air vent it can have a draft in that area and transfer a tiny particle to a different beaker and it can settle in it and a moment later it explodes. It can cause a chemical reaction. A chemical reaction is the result of an experiment. It is also important to know what mixtures to avoid. Most chemicals don’t explode unless mixed with another chemical.This is called a chemical reaction. By mixing nitric acid and methanol waste it can cause an explosion or also adding water to concentrated acid which is very exothermic will result in to splattering at the corrosive acid. It’s also important to have the right equipment for the experiment. Say if you were making gunpowder you would need sulfur, charcoal, and saltpeter. There are lots of explosive projects in chemistry .[1]

What are chemicals?
A chemical is a substance with a distinct molecular composition that is produced by or used in a chemical process.[4] A substance having a specific molecular composition, obtained by or used in a chemical process.[2]

What does a chemist do?
What a chemist does is that they gather all of their tools and they read the directions so they know what they are doing. When they are done reading the directions they mix chemicals together like, oil, and water, and other chemicals that they use. Then some of the chemicals blow up, but you have to be careful so it does not get on to your skin, or you will get sick and die. Some of the chemicals do not breathe in because you will get even more and sicker if you do. When a chemist uses oil and water they do not mix because oil and water are different type of chemicals. When chemist people mix there chemicals they do it very carefully so they don’t make it wrong while they are reading. When the chemist is done they put back the tools and they clean off the tables if they made a mess. When the chemist is all done cleaning up then the chemist makes sure the tools and tables are cleaned up.[5]
