CHEM 135 FINAL EXAM REVIEW
1. In an atom, the nucleus contains: all the protons and neutrons
2. Which of the following is a chemical change?: burning a paper
3. The energy stores in chemical bonds is: potential energy
4. Which of the following elements is a metal?: sodium
5. The temperature of a substance is -225 degrees Celsius. What is thistemperature in
kelvins?: ****add 273
48 K
6. The specific heat of a substance is the amount of heat needed to: raise thetemperature of 1
g of the substance by 1 degree celsius
7. The specific heat of copper is 0.092 cal/g C, and the specific heat of silver is 0.057 cal/g C.
If 100 cal of heat is added to one g of each metal at 25 degrees celsius, what is the expected
result?: the silver will reach a higher temperature
***silvers specific heat is smaller which means it requires less energy and will heat faster than
the copper

: Al2O3
10. What is the formula for a compound formed with beryllium and oxygen?: -
BeO
11. What is the charge on iron in FeBr3?: 3+
12. What is the name of FeO?: Iron (II) Oxide
13. What type of bond is formed between H-H: non-polar covalent
14. What type of bond is formed between sodium and chlorine?: ionic
15. Which bond will be the most polar?
A) C-F
B) C-Cl
C) C-Br: A) C-F
16. Which is larger, an atom of lithium or neon?: ***whichever element has themost
shells/electrons
Neon
17. In ionic compounds, lose their valence electrons to form posi-tively
