1. Explain the properties of the four states of matter in terms of particle arrangement, shape, size and compressibility. 2. Describe what you would see if you graphed the heating curve of water from ice to steam. Why is the heating curve not a straight line?
3. What are the four gas laws and what relationships do they represent?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
