Write out a detailed procedure for determining the enthalpy of reaction between citric acid (H3Cit) and sodium hydroxide (NaOH). Note that the neutralization reaction is: H3Cit + 3NaOH --> Na3Cit + 3 H2O Be sure to calculate what volume of each 0.50M solution should be mixed to give a total volume of 50.0mL AND the reactants in the correct stoichiometry. Also write a data table in the space given
The specific heat of lead is 0.0380cal/g degree celcius. If 47.0 calories of energy raised the temperature of a lead sample from 28.3 degrees celcius to 30.1 degrees celcius.
Calculate the number of O2 molecules it would take to consume 596 molecules of CS2.
The air is cooled as the water evaporates. How much water must be evaporated to cool the air in a room of dimensions 4.0 m x 5.0 m x 3.0 m by 20. C? Assume that the enthalpy of vaporization of water is the same as it is at 25 c.

Draw a complete lewis structure that shows all bonds, unshared electron pairs, and minimized formal charges where appropriate.
When you calculate the molarity and molality of the EDTA solution are the values very similar or not. Explain if this is what you might expect for a dilute aqueous solution with a density very close to 1.0 g/mL.
An ice cube of mass 10.0g. Is at -20oC. How much energy is needed to make the ice into steam at 172oC?

Draw a circuit diagram that has two resistors in series with a DC voltage source. If resistor one (R1) is 758 kohms and resistor two (R2) is 712 kohms, then what is the current flowing through the circuit if the voltage is 8.49 V?
An organic compound containing lead was found to contain 21.70 C and 2.7% H. The lead content was found by dissolving 4.6201g of the compound in water and adding sodium sulfate. 3.100 g of lead precipitate was collected.
