Describe the difference between the following sets of terms: strong/weak and concentrated/dilute. Provide an appropriate example using each of these terms to describe a solution
what is the molarity of a saturated solution of AgOH with a Ksp = 2.0 x 10^ -8
The normal boiling and freezing points of substance X are 87.3 K and 84.0 K respectively. The triple point is at 82.7 K and 0.68 atmosphere. a. Draw a phase diagram for substance X. Label the regions in which the s,l, and g phases are stable.
Radioactive isotope X has been found in rock units S and Q. Isotope X breaks down into isotope Z with a half life of 250 million years.
Suppose an ice cube weighing 44.7 g at a temperature of -4 degree celcius is placed in 550 grams of water at a temperature of 23 degrees celcius.
The Ksp for Al(OH)3 is 2 x 10-32. At what pH will a 0.2 M Al3+ solution begin to show precipitation of Al(OH)3.
A 493 mL sample of solution contains 33.2 g of CaCl2 Calculate the molar concentration of Cl in this solution
The half-life of C-14 is 5730 years. A fossil was analyzed and determined to have a carbon-14 level that is 50.0 % that of living organisms. How old is the fossil?
Solid aluminum reacts with aq H2 SO4 to form H2 gas and aluminum sulfate. when a sample of Al reacts, 425 mL of H2 gas is produced at 24 degree celsius at a press of 744 mmHg. How man grams of Al reacted?
