A first-order homogeneous reaction of A going to 3B is carried out in a constant pressure batch reactor. It is found that initial with pure A the volume after 12 min is increased by 70% at a pressure of 1.8 atm. If the similar reaction is to be carried out in a constant volume reactor and the initial pressure is 1.8 atm, compute the time required to bring the pressure to 2.5 atm.
The dried precipitate weighs 10.3g. Calculate the amunt of MgCl2 in the original sample (in weight percent).
water and titrated with 0.0633 M NaOH. After 10.0 mL of base has been added, the pH was determined to be 5.07. What is the Ka for the acid?
In a titration, 25.18 mL of monoprotic weak base HA is neutralized with 25.18 mL of 0.502 M NaOH. Calculate the ratio of [A-] to [HA] after 12.59 mL of 0.502 M NaOH has been added to the initil amount of HA.
