1) Percentage yield experiment: First we measured 20cm3 of sulphuric acid into a beaker using a measuring cylinder, this will help us determine the percentage yield at the end of the experiment. We then heated the beaker containing the sulphuric acid using a Bunsen burner in order to heat it up for the copper oxide to mix with. We then weighed out 1.02g of copper oxide and added it to the acid and stirred it whilst doing so, we did that until the liquid turned blue, this proves that the chemicals have mixed together. We then weighed this liquid which will help us determine the percentage yield. We then filtered the liquid off which gave us the amount we obtained.

The active ingredients in the alka seltzer tablet are “As the tablets dissolve, the sodium bicarbonate splits apart to form sodium and bicarbonate ions. The bicarbonate ions react with hydrogen ions from the citric acid to form carbon dioxide gas (and water). This is how the bubbles are made.”(Scientific American) These bubbles are representative of a chemical change and the resulting carbon dioxide should increase the water 's density. This may actually increase the volume of the water taking longer to boil, this difference may be minuscule, even negligible, but there 's a possibility for distinct change in results. This scientific American puts it best “For the reaction to occur,
There will be a stir that helps distribute the heat evenly all through the water. A temperature probe determines the amount of heat given off and converts it to joules. Components of a Bomb Calorimeter The main elements of a bomb calorimeter are: • Dewar or insulating jacket: is the body of the calorimeter which is made up of a doublewalled flask of metal with a vacuum between the two walls to prevent the transfer of heat.
They are also vegan friendly, which could be a great factor to make Rad Coffee stronger than many other coffee shops.
