Give the formulas of all new molecules or ions formed when solutions of the following are mixed. If there is no reaction write "N.R." (a) Cl-, Br- , I-, Fe3+ (b) Fe2+, Br2 water (c) Cl-, Br-, I-, Cl2 water (d) CO2 (g), Ca(OH)2 (e) SO2 (g), CaCl2, HCl (f) SO3 2-, H2O2 (acid) (g) S 2-, SO 2- (acid) (h) Pb(C2H3O2)2, H2S (g) (i) Ag+, Cl-, NH3 (excess) (j) Ag+, I-, NH3 (excess)
Type your question hereA 0.1390-g rock sample of unknown concentration was dissolved in HCl and diluted to 100.0 mL. Aliquots of 10.00 mL of this unknown solution were added to different volumes
Gold has a face-centered cubic arrangement with a unit cell edge length of 4.08 Angstrom. How many moles of gold fit in a sheet with a length of 51.6 nm, a width of 24.3 nm, and a thickness of 16.7 nm?
balanced molecular complete ionic and net ionic equations for the reactions btween nitric acid and calcium hydroxide?
A sample of an ideal gas at 1.00 atm and a volume of 1.89 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume.
Thus, as long as the concentrations of HA(aq) and A-(aq) are not consumed, the pH change is minimal compared to addition to a non-buffer solution. Why is the buffer most effective when pH = pKa?
What would you expect the measured decay rate to be 4.00 hours later? The half-life of Ru-97 is 2.79 days.
Because the turnover number for both substrates is nearly identical, what factors might be involved that explain the different ratio for the two substrates?
Determine how do you find out the new freezing point of a solution if given the formula is Delta T = m x kf x i but how do you find it how does it work?
If the temperature probe is accidentally calibrated incorrectly and at 0.0C it reads -500. C, what temperature in Celsius will the probe read at 52. F
15 g of steam at 373 K is added to 250 g of H2O (liquid) at 298K at onstant pressure of 1 bar. Is the final state of the system steam or liquid water? Calculate changes in entropy for the process.
barium metal crystallizes in a body-centered cubic lattic. The unit cell edge length is 502 pm, and the density of the metal is 3.50 g/cm3. Using this information.
sample of hydrogen gas initially at 29C and 7.0 L iscooled until its final volume is 2.9 L. What is its final temperature
