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.
What happens to the copper atoms of the penny in gold penny lab?
basically, the zinc electrons in the NaOH solution coat the copper penny and then when you wave it over a Bunsen burner, the two metals form an alloy (a homogeneous mixture with two or more elements) and make brass, not gold.
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.
What happens when you heat copper sulphate over a Bunsen burner?
I think it becomes a black liquid which, when it cools becomes a black powder. it also bubbles and gives off a gas (oxygen I think) that means that the copper sulfate had the oxygen removed making it copper sulfide. (I'm not entirely sure but this is what happened in the practical. Cheers.
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.

Bunsen burner
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.

What happens to the particles when you mix copper sulphate and iron?
Diffusion occurs - The particles of copper sulphate move between the particles iron because the particles are tiny and discrete.
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.
What happens to copper sulfate particles when they dissolve?
they fly away
