Which Equation is Correct? Copper has two oxides, Cu2O and CuO. Copper carbonate, CuCO3, decomposes on heating to form one of these oxides and an equation can be written for each possible reaction: From the two equations we can see when copper carbonate is heated or decomposed gases are given off.
To find which equation is correct we can use ideas about moles, plan and design an experiment to measure a volume of gas that will prove which of the two equations is correct.
Therefore to find out the correct equation I will need to decompose the copper carbonate by heating and after this I will measure the amount of gas produced. The volume of gas will help me determine which equation is correct. It is possible to determine which equation is correct by measuring the volume of gas given off by the decomposition.
Measuring the volume of gas will tell me which equation is correct from above.
I will need to measure the mass of copper carbonate as this will tell me the amount of copper carbonate needed in grams for the experiment and if it is correct it will show me what equation is correct.
Also the volume of gas given off depends upon the molar quantities. To do this I will need to multiply the moles and the RMM of copper carbonate.
The relative molecular mass of copper carbonate CuCO3 is Therefore this shows that if I have 0. Since one mole of copper carbonate is 1. Also if I used 0.Because, copper has two oxides Copper (I) oxide Cu2O and Copper (II) oxide CuO; therefore, there can be following two possible equations for thermal decomposi.
To work out which equation is correct I will use mole calculations to work out the amount of gas produced and then I will carry out the experiment and measure the amount of gas given off then compare the results.
If the amount of gas collected is similar to the amount of gas calculated in either equation, I will know the equation is correct.
The Correct equation is one of the most popular assignments among students' documents. If you are stuck with writing or missing ideas, scroll down and find inspiration in the best samples.
Correct equation is quite a rare and popular topic for writing an essay, but it certainly is in our database.
Equation 2 – CuCO3(s) CuO(s) + CO2(g) By using the formula for moles and the volume of gas, I am able to predict the volume of gas produced before I have actually implemented the experiment.

|Which Equation is Correct? | Essay Example||I will weigh the CuCO3 each experiment to make sure it is the same weight as in the previous experiments. I will set the clamp holding the boiling tube to a fixed position and I will not move it, just unscrew the holder to empty the boiling tube when the experiment has finished.|
