Lab Report for Chemical Changes and Conservation of Mass Lab
Previous to the reaction, the magnesium appeared to be a solid, white, black, and grey substance with many small dark particles within the substance. The hydrochloric acid was a clear liquid that looked like water It weighed 42.2 grams in total. During the reaction, the two substances produced bubbles, creating smoke and became warm with a smell that is irritating to the human nose. After the reaction, it appeared to be a clear, bubbly liquid with white spots. It weighed 42.2 grams in total after the reaction. The creation of bubbles, the different smell, and the increase in temperature told me that a chemical reaction occurred within the substance.

This is because after the reaction, the paper only weighed 27.1 grams and it had previously weighed 27.5 grams. This means that the paper lost 0.4 grams due to the reaction. However, this mass could have been released into the environment in the form of carbon dioxide gas. This could be seen in the equation provided and the smoke that the paper release when it burned. The equation showed that carbon dioxide was released after the reaction. Therefore, the combination of paper and fire to create carbon dioxide and water did not violate the conservation of …show more content…
This is because the mass remained at 59.5 grams before and after the reaction. The theory of conservation of mass states that mass cannot be created or destroyed, and this experiment supported that theory. Therefore, the combination of liquid lead nitrate and sodium iodide to create solid lead iodide and liquid sodium nitrate did not violate the conservation of mass. Experiment one is in support of the conservation of energy pertaining to chemicals because heat energy was released when magnesium (Mg) and hydrochloric acid (2 HCl) to create magnesium chlorine (MgCl₂) and hydrogen (H₂). this reaction was exothermic because heat was produced in the process and released into the surroundings. The energy did not disappear in the reaction as it was clearly released from the substance. Therefore, the law of conservation of energy was in effect during the entirety of this
