Question- How much water should be added to 10.0 mL of 12.0 M HCl so that it has the same pH as 0.90 M acetic acid (K a = 1.8 * 10^-5 )
Explain the each and every step in detail for help
Determine the degree of unsaturation of an organic compound with the molecular formula C7H6O2. interpret the value found in term of functional group of the compound.
Why could the percent composition of a nucleophilic substitution not be determined using a refractometer. by measuring the refractive index
A. In determining the percent acetic acid in vinegar, the mass of each vinegar sample is measured rather than volume. Explain.
One mole of an ideal gas expands reversibly and adiabatically from an initial temperature of 35.0 degrees C and a volume of 10.0 L to a final volume of 40.0 L. Calculate the final temperature, the final pressure, delta U and w. Assume Cp = 20.28 J..
