The 20 ml of water added to the Erlenmeyer flask is to be formerly boiled deionizer water. Since water does absorb CO2 from the atmosphere as well as since CO2 dissolved in the water causes it to be slightly acidic, will the utilization of deionized water that has not been previously boiled cause the mass of the acetic acid in the vinegar to be computed as too high or too low. Explain
An electrical heater is used to supply 145.0 J of energy to a 15.0 g sample of water, originally at 300.0 K. Determine the final temperature in degrees Kelvin. (the specific heat capacity for water is 75.291 Jmol-1K-1)
Consider a glass of 262 mL of water at 28°C. Calculate the mass of ice at -15°C that must be added to cool the water to 10°C after thermal equilibrium is achieved.
The reaction vessel is charged initially with SO3(g) and NO(g), each at a partial pressure of 0.500 atm. In the space below, enter the equilibrium the partial pressure of SO2(g) in units of atm
A generic salt, AB, has a molar mass of 243 g/mol and a solubility of 8.90 g/L at 25 C what is the Ksp of this salt
How many grams of solid barium sulfate form when 21.9 mL of 0.160 M barium chloride reacts with 66.8 mL of 0.055 M sodium sulfate. Aqueous sodium chloride is the other product.
NaOH and then 25.0mL of 0.5 M of your weak acid HA with 0.500M NaOH. How would the titration curves compare at 10 or 15 mL of NaOF beyond the equivalence points

How did changing the concentration of tert-butyl chloride affect the rate of the reaction. In part 1, we varied the concentration of the nucleophile in order to help determine the rate law.
A 6.55 g sample of aniline (C6H5NH2) was combusted in a bomb calorimeter. If the temperature rose from 22.25 ? C to 55.15 ? C, use the information below to determine the heat capacity of the calorimeter in kJ
