This experiment involves collecting data for the cooling of water between 175o-160.oF in different containers. What is 175oF in celsius? Please report your answer correctly to three significant digits.
Problem- The solubility of CuCO3 is measured and found to be 1.88E-3 g/L. Use this information to calculate a Ksp value for copper(II) carbonate.
what is steam distillation and why is it a preferred technique to purify high boiling liquids that are water insoluble?
extrapolate this "cooling curve" back to the time of addition and find that the "final temperature" after mixing is 37.9 °C. What is the heat capacity of the calorimeter cup
Problem- 1) A buffer solution contains 0.372 M KHSO3 and 0.249 M K2SO3. Determine the pH change when 0.094 mol NaOH is added to 1.00 L of the buffer.
If the pH of a solution is 4.2 (at 25 degrees C) what is the hydronium and hydroxide ion concentrations, and the pOH of the solution
For the Reaction CO(g) + Cl2(g) -> COCl2(g), the rate constant increases 1500 times when the temperature rises from 150C to 250C. Calculate the activation energy, in kJ/mol, for this reaction. Assume frequency factor is constant for both temperatu..
If the solution has the same density as well as specific heat as water, define what is PH for this reaction per mole of H2O produced. Presume that the total volume is the sum of the individual volumes.
the temperature of a household refrigerator is maintained at 0c and the temperature of the room at 25c. the heat
If the pH of the weak acid solution in is 2.34 after 7.20 mL of the NaOH was added, what is the Ka of the acid?
In a controlled greenhouse at 30.0C and 1.0 atm a crop of seeding tomato plants was found to consume 380 L of carbon dioxide gas during photosynthesis. Assuming 100% yield what a mass of glucose was produced for the growing plants?
If the pressure of CO2 is 347 mmHg measured at the same temp and volume as the origional mixture, calculate the mole fraction of the gases.
Write the total and net ionic equations for the reaction of BaSO4 dissociation, and calculate the trial Ksp for the product formed, when 40 mL of 0.1 M Ba(CH3COO)2 reacts with 60 mL 0.6 M MgSO4 and decide whether a ppt will form
