Melissa Carrithers 9-17-14 Period: 6 Determination of the Empirical Formula of Silver Oxide Purpose: To find the percent composition and empirical formula of silver oxide can then be calculated‚ based on combining the ratios of silver and oxygen in the reaction. Hypothesis: Silver oxide decomposes to silver metal and oxygen when strongly heated. Heating Silver oxide causes the oxygen to be driven off‚ leaving only the silver metal behind. The total mass of the products of a chemical reaction must

Lab 4: Kepler’s Laws (answer sheet) 1. a: semi-major axis b: semi-minor axis c: focus d: center 2. The distance from the center to a focus is 31 millimeters and the length of the semi-major axis is also in millimeters. The numbers are not even and cannot be simplified any further than what they are since 31 is a prime number. The number is 31/102‚ or 31 divided by 102 which results in 0.303921568627451. 3. Kepler’s first Law is that all planets orbit in an elliptical (egg

Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy D. F. Nachman 6/23/2010 Abstract: An ice calorimeter was used to study the reaction of magnesium metal and 1.00M sulfuric acid solution: Mg(s) + H2SO4(aq) →MgSO4(aq) + H2(g). We found the experimental molar enthalpy of reaction to be ΔH = –355 ± 17 kJ/mol at 0°C‚ 24% lower than the textbook value of ΔH° = –466.9 kJ/mol‚ reported at 25°C. Introduction Whether a chemical reaction occurs spontaneously or is driven by an outside
