I’m trying to learn for my Biology class and I’m stuck. Can you help?
1. Describe the structure of an atom and the role of electrons in forming bonds and interactions between atoms that form molecules. (ex. polar, nonpolar, covalent, and ionic bonds)
2. Explain how the structure of water molecules relates to water’s unusual properties like being a solvent and to its importance to life. (hydrogen bonds and polarity)
3. Define a chemical reaction.
4.Explain the theories of chemical evolution.
