2. What is a precipitate
- When 2 insoluble react to make another insoluble solution
- When 2 soluble solutions result in a insoluble solution
- When 1 soluble reacts to make another soluble solution
- When 2 soluble reacts to make 1 insoluble and soluble solution
3. Balancing chemical equations (sulfur+oxygen)
- S8+2O2~8SO2
- S8+8O2~8S02 (8 atoms in sulfur, 8 back, have 8 sulfur and 2 oxygen,but now 16 oxygen, put 8 in front O2, 8x2 is 16
- 2S8+O2~2SO2
4. Solubility (insoluble in water)
- Silver lead chlorides, lead barium calcium sulfates, most carbonates and hydroxides
- All nitrates, most chlorides, most sulfates, sodium potassium ammonium carbonates and hydroxide
- Sodium lead potassium nitrates, all carbonates. No hydroxide
5. Neutralisation reaction
- Is a reaction when an acid and base react to form salt and water
- A reaction where you heat up make salt from an alkaline
- Where you neturalise a solution (become neutral)
