Chemical reations Flashcards
Reactions with oxygen
Metal + Oxygen –> Metal oxide
Non-metal + Oxygen = Non-metal oxide
Reactions with acid
Metal + Acid –> Salt + Hydrogen
Reactions with water
Metal + Water –> Metal hydroxide + Hydrogen (reactive metal)
Metal + Water –> Metal oxide + Hydrogen (less reactive metal)
Neutralization reactions
Acid + Alkali –> Salt + Water
Acid + Base –> Salt + Water
Acid + Metal Carbonate –> Salt + Water + Carbon dioxide
Acid + Hydrogen carbonate –> Salt + Water + Carbon dioxide
Thermal Decomposition- using heat to break down a compound
Metal Carbonate –> Metal oxide + Carbon dioxide
Oxygen?
Light a glowing splint and put it at the mouth of a test tube, if the splint relights oxygen is present
Hydrogen?
Light a lit splint and put it at the mouth of test tube, if you hear pop hydrogen is present.
Carbon dioxide?
Bubble carbon dioxide in lime water if it turns milky carbon dioxide is present
Ammonia?
Heat the substance in the test tube and put red litmus paper at the mouth of the test tube if the litmus paper turns blue ammonia is present
Chlorine?
Put blue litmus paper in a test tube if it turns from blue, to pink to white chlorine is present.
Hydroxide
OH^-
Ammonium
NH4^+
Carbonate
CO3^2-
Nitrate
NO3^-
Sulfate
SO4^2-
How to test the purity of water?
Boil water to its boiling point (100o) if it boils at this point it is pure water
What is being used to measure the water being evaporated?
Thermometer
Anhydrous?
When water is added anhydrous it turns blue (hydrated salt)
Combustion?
Burning
Alkalid?
Proton acceptor (is either metal hydroxide or metal oxide)
Acid?
Proton donar
Diatomic?
2 atoms (HONG7)
Oxygen & magnesium
Magnesium oxide
Oxygen & hydrogen
Hydroxide Sulfur dioxide
