In a documented essay of 900-1200 words please address the following topics.
1) What is the difference between an ionic and a covalent bond? how is each formed?
2) Explain why ionic compounds dissolve more easily in water than covalent compounds. include a specific example of each type of compound and the result when each placed in water (for example, list the ions that would form or no change)
3) Describe polymers, and how they are formed. What are the benefits of polymers? provide an example of a naturally occurring polymer and a manmade polymer and the properties of each.
