Cards in this deck (30)
- 1is everything in the world made of elementsyes
- 2Is a mixture chemically bondedno its combindes
- 3What ways can a mixture be removedfiltration, evaporation, distillation and chromatography
- 4Name everyday mixtureseg: tea, water and salt
- 5How do you separate a solid from a liquidFiltration
- 6What is filtrationwith salt and sand
mix both with water
filter
evaporate salt water - 7How do you remove a soluble substance from and insoluble substancefiltration
- 8\whats solublewhen something will disolves in water
- 9what's insolublewhen something doesn't dissolve in water
- 10How do u separate 2 liquidsdistilation
- 11what happens during distillationliquids are separated during their boiling point
- 12what does the condenser doused to cool the gas back down to a liquid
- 13what's chromatographyto separate a mixture of dyes
- 14why can you only use a pencila pen will mix with the dyes
- 15what happens as temperature increasessolubility increases
- 16what is a solutea substance that dissolves
- 17whats a solventthe liquid that does the dissolving
- 18what happens when a solute is added to a solventit produces a solution
- 19whats a dilutehas a small mass of solute dissolved in a solvent
- 20whats a concentrated solutiona large mass of solute dissolved in solvent
- 21whats a saturated solutionwhen no more solute can dissolved
- 22any solution can be diluted by adding water.
- 23what happens when a coloured solution gets darkerit gets more concentrated
- 24how is a compound madewhen elements chemmically bond together
- 25compound that contain 2 or more elements finish in .........ide
- 26word equationaluminum + oxygen---------- aluminum oxide
- 27are the reactants on left or rightleft
- 28are the products on left or rightright
- 29why do you have to have an arrowto show that 'made into'
- 30how do produce copper sulfate crystalsdissolve heaped spoonful's of copper carbonate and sulphic until fizzing.
slowly filter
evaporate then leave till crystals form
