74.6 mL of a 0.655 M cadmium borate solution is mixed with 147.3 mL of a 0.606 M cadmium borate solution. Assuming volumes are additive, what is the molar concentration of cadmium ion in the resulting solution? (borate = BO33-; assume +2 charge for cadmium). M = 1.87
Draw the product of the reaction between 1-butyne and NaNH2 in NH3, then D3O+. To add a deuterium atom, first explicitly add an H.
Furoic acid, HC5H3O3, has a Ka value of 6.76 10-4 at 25°C. Calculate the pH at 25°C for each of the following.
