Can someone do several chemistry assignments for me?

ChemActivity #1

The Scientific Method

Model:

Steps in the Scientific Method: 1) Make (an) observation(s).

2) Make a prediction (i.e., formulate a

hypothesis) based on the observations.

3) Perform experiments to test the hypothesis.

4) When the experiments agree with the predicted outcomes, a theory or model is formed.

Critical Thinking Questions:

Consider the light bulb experiment:

1. What was the result with pure, deionized water?

2. What was the result when table sugar (sucrose), a molecular solid, was dissolved in the water?

3. What was the result when table salt (NaCl), an ionic solid, was dissolved in the water?

4. What is your conclusion regarding molecular solids dissolved in water?

5. What is your conclusion regarding ionic solids dissolved in water?

6. What is your prediction in a similar experiment using grape sugar (glucose), a molecular solid?

7. What is your prediction in a similar experiment using potassium chloride (KCl), an ionic solid?

8. Think of a problem and write how you would solve the problem using the Scientific Method?

a) State the problem:

b) Make an observation:

c) Formulate a hypothesis:

d) Describe experiments that will test the hypothesis:
