Chapter 4 - Analysis Of World Resources Flashcards
What is the rate if reaction
How quickly reactants turn into products
How do you calculate the rate of reaction on a graph
Draw a tangent. Make it form a right angle triangle. Find the measurement (g). Find the time (s). Do time/measurement
What are the factors that affect the rate of reaction
Temperature
Solution concentration
Pressure
Surface area
What are reversible reactions
Where the products can react to make the original reactants
What is a closed system
Where no reactants or products can escape
What is dynamic Equilibrium
Where the amount of reactant and product are constant
What is crude oil
Oil formed from the remains of a ancient biomass
What are most of the compounds of crude oil
Hydrocarbons
What are the four main alkenes
Methane
Ethane
Propane
Butane
What is the formula for alkenes
Cn H2n+2
What is a pure and impure substance
Pure is made up of one element. Impure is made up of different elements
What are 4 methods of separating mixtures
Filtration
Crystallisation
Simple distillation
Fractional distillation
What is chromatography
Separates different components of a mixture
