1-1: Insert the chemical symbol in the answer blank for each of the following elements.

The phase diagram is a simulator representing how much pressure can be added and the different forms of your substance (whether it's liquid, solid or gas.) in different environments and put to observation tests. The three regions are solid, liquid and gas. Gas when heated spreads everywhere and moves rapidly. When gas is frozen it falls to the bottom and gets stuck together as if it was a solid or a liquid. Liquid when heated boils, then turns into gas and builds up pressure. Eventually enough pressure to blow the lid off. Liquid when frozen turns into a solid. Solids when heated turns into a liquid, then soon evaporates and becomes a gas. When a solid is frozen it stays as a solid.

4. Write a structural diagram equation to represent the reaction between each alcohol and HCl(aq).

The structure and molecular weight and formula for benzoic acid are as seen in Figure 1. This chemical is used as a preservative, and is deemed safe for consumption under specific levels.5

2. Bubble in your last name, skip a space, and then your first name on the scantron.

2. Using the atom and bond library below, construct the following molecule. It may be

A 3. C 4. D 5. B 6. B 7.

Why are spindle fibers important for mitosis? (5 points) Chromosomes use spindle fibers as pathways to daughter cells during mitosis.

Please be prepared to transfer your answers to a scantron when you arrive at the final. Bring #2 pencils.

Look at the study guide for week 3 (in the Unit 3 Learning Guide), and choose one of the items you need to know for the exam, and then answer it, and explain it to me in full.

D. A sample of gold (Au) has a mass of 26.15 g. Given that the theoretical density is 19.30 g/mL,

The Grignard reaction is an important synthetic process by which a new carbon to carbon bond is formed. Magnesium metal is first reacted with an organic halide forming the Grignard reagent. The Grignard reaction is the addition of an organomagnesium halide (Grignard reagent) to a ketone or aldehyde, to form a tertiary or secondary alcohol, respectively. For example, the reaction with formaldehyde leads to a primary alcohol. Grignard Reagents are also used in the following important reactions: The addition of an excess of a Grignard reagent to an ester or lactone gives a tertiary alcohol in which two alkyl groups are the same, and the addition of a

For the following molecules determine which atoms are bonded (write the symbols with a bond between them), the electronegativity difference between them, and the type of chemical bond it represents. If the bond is ionic, state what ions are produced. If the bond is polar covalent, indicate the direction of the dipole on the symbols from the first part.

After putting the CH2Cl2 to a beaker containing the drying agent anhydrous sodium sulfate, a sticky white solid was recovered.
