Answers
Answer:
1.Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions.
2.
Metals displace hydrogen from dilute acids. Non-metals do not react with dilute acids
Metals form ionic chlorides with chlorine
Non-metals form covalent chlorides with chlorine
3.atom is the smallest unit of an element that can or cannot exist freely. While on the other hand, a molecule is a set of atoms that are held together with the help of a bond and is the smallest unit of a compound. Furthermore, an atom can or cannot exist in a free state.
4.Monatomic compounds are composed of single atoms and there are no chemical bonds between these atoms. Diatomic compounds are composed of molecules containing two atoms.
5.preservatives are used with the basic goal of keeping food fresh and limiting the growth of microbes, while additives are used to enhance flavor and appearance
Pesticides are chemicals that may be used to kill fungus, bacteria, insects, plant diseases, snails, slugs, or weeds among others
