chemical reactions and equations
| Question | Answer |
|---|---|
| reactants | the starting substances in a chemical reaction |
| products | ending substances in a chemical reaction |
| diatomic gases | HOFBrINCl Hydrogen Oxygen Fluorine Bromine Iodine Nitrogen Chlorine |
| element+element--> | compound |
| metal+oxygen--> | metallic oxide (basic anhydride, or base without hydrogen) |
| nonmetal+oxygen--> | non-metallic oxide (acidic anhydride) (carbon diOXIDE, sulphur diOXIDE) |
| metallic oxide(basic anhydride)+water--> | base (write water as HOH) |
| nonmetallic oxide+water--> | acid |
| metallic carbonate--> | metallic oxides + carbon dioxide |
| metallic carbonate exception | ammonium carbonate decomposes into ammonia, carbon trioxide and water |
| metallic chlorate--> | metallic chloride + oxygen |
| metallic hydroxide (base)--> | metallic oxide (basic anydride) + water |
| metallic hydroxide NO REACTION | sodium hydroxide (NaOH) potassium hydroxide (KOH) |
| acids--> | non-metallic oxide (like sulphur diOXIDE, carbon diOXIDE) + water |
| metallic oxide--> | metal + oxygen |
| compound--> | elements |
| single replacement | metal in compound, hydrogen in water, hydrogen in acid, halogen replacing |
