1. Synthesis Reactions!

2. Synthesis Reactions - Combination Reaction
- Multiple reactants combine to form a single product.
- A + B → AB
- Release energy in the form of heat and light (exothermic)

3. Examples with elements
Sodium + chlorine → Sodium Chloride
Carbon + oxygen → Carbon dioxide or carbon monoxide (but not both!)
2Na+Cl2-> 2NaCl
CO + O2 → CO2 or CO

4. Examples with Compounds
Calcium oxide + water → calcium hydroxide
Sulfur dioxide + oxygen → sulfur trioxide
CaO + H2O → Ca(OH)2
2SO2 + O2 → 2SO3

5. The synthesis of Iron Sulfide
Iron and sulfur are heated to form iron (II) sulfide
Fe + S → FeS
Note that the video uses temperature to increase the rate of reaction and spreads it out to increase surface area (also increases the rate of reaction)

6. Predicting the products
Non-metal + oxygen → nonmetallic oxide nitrogen + oxygen → nitrogen dioxide
Metal + oxygen → metallic oxide
Magnesium + Oxygen → Magnesium oxide

7. Metal-oxide + water → metallic hydroxide magnesium oxide + water → ?
Magnesium hydroxide! Mg+02 → Mg2+(OH)1- Mg(OH)2

8. Non-metallic oxid + water → acid
carbon dioxide + water →

9. Non-metal + metal → salt

10. Bonus Nitrogen + Hydrogen → ammonia
Ammonia + water → ammonium hydroxide
