CaCl2 + CO2 + H2O 2.0 Aim, scheme and Prediction 3.1 Aim The develop of this experiment is to investigate the effects on heartburn when a tabloid (TUMS) is at different temperatures. 3.2 guessing When the inkpad is heat the particles move around faster looseness the tablet. 3.3 Prediction The hotter the tablet the faster the tablet will disrupt within the Hydrochloric harsh. 3.0 investigate Design 4.4 Variab les and Controls Type Of Variable| Independent | dependent | Controls| Characteristics:| Temperature of check| Time taken for acid to react with tablet| * same(p) sizing beaker * Same Stopwatch and timer * Same amount of hydrochloric acid * Same number of tablets| Reason| The unlikeness in temperature has been changed by choice with the Bunsen burner.

| The time will quit due to how fast the hydrochloric acid breaks it down.| The variables must be controlled so the experiment is a fair test otherwise the experiment is not accurate.| 3.2Equipment list -2m Hydrochloric pungent- 100mL beaker- Mylanta tablet -Stopwatch- Water- Bunsen b! urner -Gas-Tongs -Matches (light Bunsen burner) -Tongs 3.3 sentry duty judgment See Risk Assessment sheet for safety hazards 3.4Method -20mL of Hydrochloric Acid was poured into a beaker -The 1st tablet was placed into the HCL and the time from feature article to finish -The beaker was than thoroughly rinsed out and another 50mL of Hydrochloric Acid was once more poured...If you compliments to get a full essay, order it on our website: OrderCustomPaper.com
