I just tried that and it told me the answer was incorrect. It gave a hint saying In acidic solution, use the reaction given for the solvation of CaCO3 in acidic solution. Construct a concentration table that allows for the calculation of final concentration as if the reaction ...
Compare the g/L solubility of CaCO3 in pure water, a H3O+ (aq) solution with a PH of 3.00 and a H30+(aq) solution with a pH of 1.00. Ksp for CaCO3 is 3.36 x 10^-9 CaCO3 (s) + H3O (aq) = Ca (aq) + HCO3 (aq) + H2O (l) (equilibrium equation) Keq= 71 I knew how to do this for pure...
Chlorine gas is collected in a gas collecting tube above water. The gas is at 20oC and the total pressure in the tube is 755 mmHg. What is the pressure (in mmHg) of chlorine gas in the tube?
The breaking strength (in pounds) of a certain new synthetic is normally distributed with a mean of 175 and a variance of 4. The material is considered defective if the breaking strength is less than 170 pounds. What is the probability that a single, randomly selected piece of...
Your grandfather clocks pendulum has a length of 0.9930 m. If the clock loses 95.6 seconds per day, by how many millimeters should you adjust the length of the pendulum?
What is the period of a simple pendulum 83 cm long on the Earth?
A pendulum has a period of 4.28 s on Earth. What is its period on Mars, where the acceleration of gravity is about 0.37 that on Earth?
Suppose that people's heights (in centimeters) are normally distributed, with a mean of 170 and a standard deviation of 5. We find the heights of 80 people. (a) How many would you expect to be between 170 and 175 cm tall? (b) How many would you expect to be taller than 179...
