# Which equation is correct for this reaction involving Copper Carbonate?

Extracts from this document...

Introduction

WHICH EQUATION IS CORRECT??? 1. 2CuCO3 (s)-------- Cu2O (s) + 2CO2 +1/2O2 (g) 2. CuCO3 (s) --------- CuO (s) + CO2 (g) I will carry out an experiment, which will tell me which of the two equations is true. To do this I will measure the amount of gas given off in the reaction. From my calculations I can work out which equation is true, as equation 1 gives out more gas than equation 2. I shall use the following apparatus: Stand Clamp Boss Gas syringe Delivery tube Bung Boiling tube Bunsen burner Heat proof matt Test tube holder Diagram: I will add 0.337g of copper carbonate (green powder) ...read more.

Middle

Any water vapour that was given off will cool at this point so will not affect my results. The experiment should be repeated twice more for an average reading to be obtained. A gas syringe is used because it is a very accurate way of recording gas. The gas in the gas syringe must have cooled to room temperature before a reading is taken, as this will affect the accuracy of the results. Basic cooper carbonate contains 61 % by mass of CuCO3. The relative atomic mass of CuCO3 is 123.5g. 123.5/61 * 100 = 202.45, 1 mol of Basic copper carbonate has the mass of 202.45g. ...read more.

Conclusion

Gas also expands when heated so this will have to be considered. I will aim to collect around 50 cm3 of gas. 1. 202.45/30,000 * 50 = (0.337 mol) 50 cm3 2. 24,000/30000 * 50 = 40 cm3 I will use 0.337g or basic copper carbonate, Equation 1 if true will give out 50 cm3 of gas; equation 2 if true will give out 40 cm3 of gas. 1 mol of any gas at room temperature and 1 atmospheric pressure will occupy a space of 24dm3. From this and the amount of gas given off I can work out the mol of the gas given off and find out which of the two equations are correct. ...read more.

1. ## The idea of the experiment is to determine which equation is correct. There are ...

5 star(s)

I made sure that all the CuCO3 had turned black so that all the gas will be given off by heating the test tube uniformly under a Bunsen burner. 4. For my two experiments, I used the same boiling tube so that the volume of air in the test tube wouldn't change for the 2 experiments.

2. ## Which Equation is Correct?

Diagram of an endothermic reaction Fair Testing The conditions must ensure a fair test, certain variables must be maintained, the main variable that has to be kept the same is temperature, the collected gas should be kept at room temperature, the gas syringe should be kept as far away as possible when heating the copper carbonate.

1. ## Which Equation is Correct?

* I will make the copper carbonate into powder to increase its surface area and thus increasing the rate of reaction. * I will be able to obtain more readings in the time period so a more precise average can be produced.

2. ## Determining the Correct Equation for the Decomposition of Copper Carbonate.

colour, has changed fully to a black colour which is the colour of copper oxide. Another method, which I shall also employ, is by looking at the gas syringe. We can tell when the reaction has stopped due to the fact that when the Copper carbonate has finished decomposing gas will stop being produced.

1. ## Which equation is correct?

Report to teacher in case of injury. Digital weighing scale/Balance Electric shock and falling over plug wires Make sure plug wires are safe were people cant fall over. Keep away from water. Report to teacher if serious. Method/Procedure 1. First of all weigh 0.26grams CuCO3 and place it directly in the boiling tube.

2. ## Right equation

1/2 Cu2O (s) + CO2 (g) + 1/4O (g) Decomposing 1 mole of Copper carbonate will produce half a mole of copper oxide (solid), 1 mole of carbon dioxide (gas) and 1/4 oxygen (gas) are formed. Both carbon dioxide and oxygen gases are collected together; therefore the total volume of gas produced is 1.25 moles.

1. ## Determine which of two equations below is the correct equation of the thermal decomposition ...

It can be tested for by bubbling it through limewater, the limewater will turn milky. The mole A mole is defined as the quantity of a substance that has the same number of particles as are found in 12.000 grams of carbon-12.

2. ## To find out the correct formula, I will need the aid of an experiment. ...

Calculations: Formulas used are: Moles= mass/M 1 mole of gas occupies 24000cm� of space under standard conditions. Equation 1: 2CuCO3(S) Cu2O(s) + 2CO2(g) + 1/2O(g) According to this equation, 2 moles of CuCO3 will produce 21/2 moles of gas. So the ratio of copper carbonate to gas is 2:21/2.
