What is the pH of a solution containing 0.10 L of 0.10 M acetic acid, to which 0.010 moles of acetate are added. Volume does change in this case. Density of the acetate salt is 55.05 g/mL
After heating, the remaining solid weighed 0.427 g. Assuming all the CaCO3 broke down to CaO and CO2, calculate the mass percent of CaCO3 in the original mixture.
An isolated tube contains 1 mole of argon at 5atm on one side of a movable barrier held in place by a pin. On the other side of the barrier is 0.2 mole of neon at 0.5atm, the the whole system is at 298K.
Cyclopropane contains 85.7%C and 14.3% H by mass. At 50C and .984 atm pressure, 1.56g cyclopropane has a volume of 1L. What is the molecular formula?
If the colder block originally weighed 200g and the warmer one 100g, calculate the final temperature and the entropy change of the universe for this process.
What is the rate law for the reaction? Please show step by step solution.
Write a procedure that would follow to demonstrate the effect of increasingly higher concentrations of hydrochloric acid on its rate of reaction with antacid tablets. Can only use materials listed:
The reaction OH(aq) + HCN(aq) H2O(l) + CN(aq) is first-order in both the OH and HCN concentrations. The rate constant at 25oC is 3.7×10^9 mol^-1 L s^-1. In an experiment, 0.500 L of 0.020 mol L ^-1 NaOH(aq) is rapidly mixed with an equal volume of..
