List five isotopes
```
Na-24
Fe-59
Chlorine-36
Pu-239
Ti-201
```
27
What does na-24 do?
Location of leaks in water pipes, studies on body electrolytes.
28
What does Fe-59 do
Used in blood studies, when combined with steel it can determine the amount of friction in machinery.
29
Cl-36
Measurement of sources of chlorine, can determine the age of water up to two million years old.
30
Pu-239
Fuel for most "fast breeder" nuclear reactors
31
Ti-201
Locating damaged heart muscle
32
How do you properly use a Bunsen burner?
1. Safe area
2. Check tubing for cracks, secure to gas valve and Bunsen burner.
3. Have air port nearly closed.
4. Slowly turn gas valve to be aligned with the tube.
5. Use flint held sideways and spark.
6. adjust flame.
7. Never leave unattended.
33
How to properly use a balance
1. Make sure it is zeroed out without any object on its platform,
2. Never place chemicals directly on platform. Use a container.
3. Move larger rider one notch at a time until it causes the pointer to drop. Move it back one and repeat with rest of riders.
4. Add up final total.
34
What are three cases and their solutions to adjusting flames.
Flame to big- decrease gas
Flame disappears- reduce air, light again
Flame too yellow- increase air flow
35
