Combustion and Corrosion reactions Flashcards
What are reactants?
Substances you started with
What are products?
Substances that are formed
What is an endothermic reaction?
Absorbs energy from there surrounding because the products have more energy than the reactants, making it cool, cold.
What is an exthothermic reaction?
Releases energy, producing heat, light.
What is combustion?
An exothermic reaction
How does combustion occur?
When something reacts with oxygen making it burn or explode
What does combustion always need?
Oxygen gas
How do bunsen burners produce a blue flame?
Burning methane or ethane gas in oxygen
Methane gas/ethane + oxygen gas =
water vapour + carbon dioxide
What are hydrocarbons?
Highly combustible chemicals
Octane + oxygen gas =
carbon dioxide + water vapour
What is incomplete combustion?
When oxygen is restricted and does not release as much heat or light as combustion does
What do incomplete combustion produce?
Carbon and carbon monoxide
Magnesium + oxygen gas =
magnesium oxide
What is corrosion?
Chemical reactant hat breaks down some metals to form other compounds.
