In this lab, we carried out a variety of reactions using different chemicals and metals. A chemical reaction is when the chemical state of the substance you are testing rearranges its ionic and molecular structure. One of the reactions we experienced was single replacement, this consists of one ion switching places with another ion to form a new compound. Another reaction we saw was double replacement. In this reaction, two compounds ions are switched to form two new compounds. Another reaction we saw was synthesis. This reaction takes two ions and combines them to form a new compound. Combustion was the last reaction we saw. In this reaction, a hydrocarbon and oxygen compound breaks into a carbon dioxide and water compound. We know when a
