6.25 g of HCl(g), a strong acid, is dissolved in water to make a 280-mL solution. Calculate the pH of the resulting solution.
Step 1: Calculate the number of moles of HCl(g) mol.
Step 2: Determine the number of moles of H3O+(aq). moles.
Step 3: Determine the concentration of H3O+(aq). mol/L.
Step 4: Calculate the pH.
A disk has a moment of inertia 3.0 x 10-4 kg. m2 and rotates with an angular speedof 3.5 rad/sec. What net torque must be applied to bring it to rest within 3 s
Aldehydes react with KCN and HCN to form cyanohydrins. The nitrile may be further converted to a carboxylic acid or -CH2NH2. Carry out the synthesis of a cynohydrin from cyclopentanecarboxaldehyde and convert it to a carboxylic acid and a -CH2NH2.
This solution was examined and the instrument reply for the unknown was 1.69 times the signal due to the standard. In a separate experiment, it was found that for equal concentrations of element X as well as the standard the response for element X..
