We will use triethanolamine and take a 60.00 mL of a 0.1800 M solution of it and 60.00 mL of a 0.1200 M solution if its conjugate acid. What is the pH of this combined solution? Always give two numbers after the decimal place!
When 31.7mL of 0.235M Potassium hydroxide is required to completely neutralize 26.0mL of a HC 2 H 3 O 2 solution, calculate the molarity of the acetic acid solution.
How many moles of CO(NH2)2 are present in 105 g of water, if the freezing point of the solution is -4.02C? kf(water) = 1.86 K · kg/mol.
calculating theoretical yield for this experiment. It is a dehydration synthesis where one mol of hydrated salt yields 3 mol hydrates and 1 mol of anhydrous salt.
Conductivities are often measured by comparing the resistance of a cell filled with the sample to its resistance when filled with some standard solution, such as aqueous potassium chloride. The conductivity of water is 76 mS m^?1 at 25°C
The observed melting point of camphor is often low. Look up the molal freezing point depression constant K for camphor and calculate the expected depression of the melting point of a quantity
Identify the steric number, shape, hybridization about the central atom and molecular polarity of sulphuryl chloride, SO2Cl2.
Indicate the reaction conditions you would employ to accomplish the following: Conversion of tert-butyl chloride to 2-methylpropene to maximize the yield of the elimination product over the substitution product.
What is the pH of a solution that is 0.10 M CH3NH2 (methylamine) and 0.15 M methylammonium chloride
if 1.205 g of KHP required 25.25 mL of NaOH solution for complete neutralization, what is the molarity of the NaOH sodium hydroxide solution?
What is the final volume of the balloon? Assume ideal-gas behavior. A very flexible balloon with a volume of 1.2 L at 1.0 atm at 300 K is allowed to rise to the stratosphere
Imagine two solutions with the same concentration and the same boiling point, but one has benzene as the solvent and the other has carbon tetrachloride as the solvent
A 757 mL gas sample at STP is compressed toa volume of 202 mL, and the temperature isincreased to 30 degrees C. What is the new pressureof the gas in Pa?
