Charles’s Law – Lab Report Charles’ Law: Assuming that pressure remains constant‚ the volume and absolute temperature of a certain quantity of a gas are directly proportional. Mathematically‚ this can be represented as: Temperature = Constant x Volume or Volume = Constant x Temperature or Volume/Temperature = Constant Substituting in variables‚ the formula is: V/T=K Because the formula is equal to a constant‚ it is possible to solve for a change in volume or temperature using a proportion

Analysis of a Chemical Mixture Using the Ideal Gas Law The objective of this experiment was to determine the composition of the NaNO2 mixture in the net ionic reaction of NO2-(aq) + HSO3NH2(aq) → HSO4-(aq) + H2O(l) + N2(g) in unknown mixture number nine. It was known that NO2-(aq) and HSO3NH2(aq) were in a stoichiometric 1:1 molar ratio. In trial one the percent mass of NaNO2 in the unknown mixture was 59.30%. In trial two‚ the percent mass of NaNO2 was 63.47%. Lastly in trial three

Common Name: Pearl Scientific Name: Calcium Carbonate Formula: CaCO3 Fundamental particles: Pearls are comprised of a positive Calcium ion (Ca+) and a negative Carbonate polyatomic ion (CO3+) Usage: Jewelry Properties: Pearls are good jewelry because they are hard and lustrous. Pearls are hard because of the strong Intermolecular forces created between the Calcium and the Carbonate ions. The pearls luster is dependent on the amount of nacre excreted. The Oyster produces nacre when

Abstract: By manipulating the ideal gas law (PV=nRT)‚ we will be determining the molar mass of an unknown volatile liquid. Heating a flask filled with an unknown‚ easily evaporated liquid will allow for measurements that can be taken to work out the ideal gas equation. This lab will require knowledge of basic equations used in chemistry. Using these equations‚ such as density and number of moles(n)‚ we can substitute different values into the ideal gas law to manipulate it. II. Materials:

LAB REPORT ON VERIFICATION OF HESS’S LAW Our purpose of doing this lab was to prove the Hess’s law correct. Hess’s law suggests that the enthalpy change of a reaction must be equal to the sum of the enthalpy changes of the related reactions which lead to the original reactions. The following are the reactions at the lab; 1) NaOH ( s) NaOH (aq) 2) NaOH (aq) + HCl (aq) NaCl (aq) + H2O (l) 3) NaOH (s) + HCl (aq) NaCl (aq) + H2O (l) As explained before‚ Hess’s Law states that the enthalpy
