Boric Acid!
When boron is heated, electrons absorb a certain amount of heat energy that causes them to jump to higher energy levels. After While, these electrons lose their energy and fall back down to their original levels, and as they do so, they emit energy in the form of light. Because the energy absorbed by electrons is different per element, each element will give a different color.
Boron gives off a green color.

What causes a Bunsen burner to make noise?
If you let hydrogen gas near the flame it will pop. The way we got hydrogen gas is by adding hydrochloric acid to magnesium powder and putting our thumb over the top of the test tube trapping the hydrogen gas then releasing it near the flame of the Bunsen burner.
Describe the procedure of making copper sulphate crystal using copper oxide and sulfuric acid?
Equiptment: Bunsen Burner, tripod, Gauze, heatproof mat, basin, stirring rod, spatula, measuring cylinder, Funnel, filter paper, Chemical; CuO+H2SO4First measure 20cm3 of sulphuric acid, H2SO4, using a measuring cylinder and pour it into the beaker.Take 1 spatula of copper (II) oxide and put it into the same beaker.stir the mixture using a stirring rod to ensure complete neutralisation of the acidAdd excess CuO if required.Filter the mixture into a basin.Turn on Bunsen burner but make sure it is on the heatproof mat, and then put the tripod on top of the Bunsen burner followed by the Gauze and basin containing CuSO4.Heat the filtrate until you begin to see crystals forming around the basin.Turn off Bunsen burner and leave to dry.
How is salt obtained using the titration method?
an exact volume of the acid is titrated on the base and then placed on a Bunsen burner to be boiled for some time.it can be observed that the salt crystals will be left in the conical flask
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.

How do you test the copper two ions?
A Flame Test. Using a platinum or nichrome wire. Clean the wire in hydrochloric acid, Then dip the wire into a solution containing copper(II) ions. e.g. copper sulphate solution. The pass the wire through a Bunsen burner flame. The flame should burn a green/blue colour.

On heating, Orthoboric Acid above 370K forms metaboric acid, which on further heating yields Boric Acid.
