CALCULATIONS Determining the amount Limiting Reagent used. nlimiting reagent = Molarity x Volume or Mass / Molar Mass Example: Limiting reagent is 5mL of 1.0 M HCl nlimiting reagent = Molarity x Volume nlimiting reagent = (1.0 [mol/L]) x 0.005 [L]) = 0.005 mol Determining the qrxn and qcal. qrxn + qcal = 0 -qrxn = qcal qrxn = ΔHrxn x nlimiting reagent qcal = Ccal ΔT qrxn = - Ccal ΔT + mcsolid ΔT (note: only if there is a precipitate formed in the reaction)

In order to describe the molar volume of pure water the equation V_3=M_3⁄ρ_(3 ) is used‚ whereas those of sodium nitrate and the polyether compound poly(ethylene glycol) (PEG) are shown by V_1=V_(∅_1)^∞and V_1=V_(∅_2)^∞. In these two equations‚ V_(∅_1)^∞ and V_(∅_2)^∞ which are the apparent molar volumes at infinite dilution of sodium nitrate and poly(ethylene glycol)‚ must be computed on the basis of data on apparent molal volume (V_∅). The following equation shows the relation of the V_∅ of a

The FBI agent‚ Sarah Ashburn‚ only agreed to take on this case to get a promotion. The Boston cop‚ Mullins‚ was chosen to do this case because she knew the town better than anyone else did. Sarah Ashburn and Mullins did not like each other

8/2/15 Lab Report Experiment to measure the latent heat of vaporisation of water Theory Latent heat of vaporisation is when a liquid is heated enough to start boiling‚ at this point‚ even if the source of heat keeps heating the liquid‚ the liquid’s temperature will not rise any further until all of the liquid is converted to gas. For example‚ if water is boiling in a kettle‚ and the kettle is left on whist the water is boiling‚ the water’s temperature will not exceed 100°C because all the heat energy

Vapor Pressure and Heat of Vaporization Introduction: Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. If the temperature inside

Heats of Reaction Lab Report Purpose: To measure the heats of reaction for three related exothermic reactions and to verify Hess’s Law of Heat Summation. NaOH(s) ( Na+(aq) + OH-(aq) ΔH = -10.6kcal/mol NaOH(s) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -23.9kcal/mol Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -13.3kcal/mol Background: Energy changes occur in all chemical reactions; energy is either absorbed or released. If energy is released in

Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises

Specific Heat and Conservation of Energy When energy in the form of heat Q is added to a material‚ the temperature of the material rises. Note that temperature‚ in units of degrees Celsius (°C) or Kelvin (K)‚ is a measure of how hot or cold a substance is‚ while heat‚ in units of joules (J) or calories (cal)‚ is a measure of its thermal energy. 1cal = 4.19J. A measure of the efficiency with which a substance can store this heat energy is known as specific heat capacity‚ or simply the specific heat‚ . The
