What happens to the particles in copper when heated by a Bunsen burner?
[object Object]
What is the apparatus for heating copper metal?
Bunsen burner
What is the evidence that indicates that both physical and chemical changes occur when a copper wire is heated in a Bunsen burner flame?
When a copper wire is heated in a Bunsen burner flame, the copper's color changes to become a glowing red. It won't be restored to its original appearance after cooling. Instead, it becomes a black material called copper (II) oxide, which is 79.9% copper and 20.1% oxygen (was 100% copper before it was burned). This chemical change occurred as the oxygen in the air combined with the copper during the heating process.
A sample of copper powder is heated in an evaporating dish using a Bunsen burner If the mass of the powder in the evaporating dish increases after heating this indicates that?
the copper must have combined with another substance.
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 do you use a Bunsen burner to kindle the copper metal?
You open th Bunsen burner. Then you use a metal grabber to grab the copper metal and put it on top of the Bunsen burner's flame. Soon the cooper metal will be kindled.

How do you make a compound with copper and sulfur?
copper sulphate?heat together in an evaporating basin on a gauze above a Bunsen burner and stir maybe?
Bunsen burner parts?
A normal Bunsen burner has a chimney which contains gas, a collar to adjust the air hole, a air hole that will leak gas, a gas tap that provides gas to the burner and the rubber tubing leads gas to the burner.

A reddish brown rock from the Canadian shield was held in a very hot Bunsen burner flame The flame appeared emerald green what metal was likely present in the rock?
Copper
Why does sodium carbonate not decompose when using a Bunsen burner?
because its a single, stable element. its not like copper carbonate, which is a compound of more that one element; here these elements can break apart
