How fast is your reaction? Part 1 – How temperature affect the rate of reaction Chemical equation Magnesium + hydrochloric acid → magnesium chloride + hydrogen Mg + 2HCL → MgCl2 + H2 Graph Conclusion and questions 1. What factors/variables did you keep the same in this experiment? * We kept the same volume of hydrochloric acid (10 cm3) and the magnesium ribbon (5cm) because that way we could get a fair test experiment. We also repeated

which a solid passes directly to the gaseous state and back to the solid state without the appearance of the liquid state is called Sublimation. Experimental: The materials that we use it in this experiment are unknown mixture of sodium chloride‚ ammonium chloride‚ and silicon dioxide. Also‚ we use some apparatus such as balance‚ tongs‚ evaporating dishes (2)‚ watch glass‚ 50 or 100 ml graduated cylinder‚ clay triangles (2) or wire gauze (2)‚ glass stirring rods‚ ring stands (2)‚ iron rings

IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

PHYSICAL PROPERTIES OF THE PERIOD 3 OXIDES These pages explain the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn’t form an oxide. A quick summary of the trends The oxides The oxides we’ll be looking at are: |Na2O |MgO |Al2O3 |SiO2 |P4O10 |SO3 |Cl2O7 | | | | | |P4O6 |SO2 |Cl2O
