How do you separate charcoal powder from mixture of copper oxide?
i did this in a lab using methods of solution, filtration and evaporation : add dilute sulphuric acid to the solid/solid mixture ..heat on a Bunsen burner till bubbles appear then filter the solution, collect the filtrate in an evaporating dish and heat on a Bunsen burner until most the water evaporates or half the filtrate has evaporated .....remove the dish from the burner and leave it on a flat undisturbed surface for 48hrs to allow crystallization.
Can you heat a graduated cylinder?
Heat it to what as long as it pyrex should be ok till hit melting points
Why does a thermocol glass containing water or ice does not burn when provided with heat?
Because the heat supplied to thermocol is absorbed by the water inside thermocol and this continues till the temperature reach the boiling point of water. Once the temperature reaches to boiling point of water then the temperature of water inside the thermocol is same as the temperature on the outer side of thermocol facing the heat and then only the thermocol glass will start burning.
What Happens to particles when steam condenses?
Actually when steam condenses it is loosing heat. As steam rises it cools and falls back down with gravity. I.E. a steam boiler heat system Boils water to till it turns into a gaseous mixture of water droplets and rises to a radiator to heat. As the radiator absorbs the heat from the steam It condenses and returns to the boiler through the same riser pipe to the boiler.
What are the identification tests for citric acid?

Where to apply the method of evaporation till dryness and crystallization?
For example in the process of table salt extraction from the seawater.
What is the procedure for making and isolating sodium chloride from sodium carbonate?
put the mixture in water and add hydrochloric acid the carbonate becomes decomposed when no further bubbles appear by adding hydrochloric acid then heat the mixture till dryness and get the solid sodium chloride.
How can you get copper sulphate from an impure sample?
1. Dissolve the copper carbonate/sulfate salts in water and filter it: the Copper Carbonate is insoluble so it will remain as the residue on the filter paper, and the copper sulfate is soluble so it will pass through the paper as the filtrate. 2. Heat the filtrate in an evaporating basin till the point of crystallization (crystals will form on a rod dipped into the mixture, at the point of crystallization). 3. Leave the filtrate to cool and crystals of pure Copper sulfate will form. Collect the crystals with a spatula and leave them on a sheet of filter paper to dry.
