At a certain temperature, the solubility of potassium iodate, KIO3, is 41.1 g/L. Calculate its solubility product constant for this temperature.
70g of ice at 0 degrees celcius. is added to 355mL of water at 25 degrees celcius. Find the final temperature of the water when the ice is fully melted
Electrolysis is used to gold plate jewelry made of stainless steel. a) what half reaction takes place to plate Au^3+ on a stainless steel earring? b) is the earring the anode or cathode? c) why is energy needed to gold plate the earring
For each reaction, identify the acid-base conjugate pairs. Then rank all reactions in order of increasing tendency for the reaction to go to completion (to the right).
When 8.6 g of toluene is mixed with 9 g of pure nitric acid, only 6.7 g of trinitrotoluene (TNT) is recovered from the mixture when it is separated from other undesired byproducts. What is the percent yield of the synthesis? C7H8 + 3 HNO3(l) ? C7H..
What are the potential effects of exposure to nitric acid? Consider all different modes of exposure listed on the MSDS.
A sugar water mixture contains 45.8g of sugar and 108.5 g of water. What is the percent by mass of sugar and the percent by mass of water in the solution?
A buffer solution containing 0.25 M Acetic acid and 0.56 m Sodium acetate. After addition of 0.0060 mol HCL what is Ph of buffer.
If 525 mL of gas at 25 degrees is heated to 50 degrees at constant pressure, calculate the new volume of the sample gas.
what is the minimum rate that fresh air has to be supplied to the room so that the concentration of CO2 in the room doesn't exceed 0.500% by mole? Assume the room is well mixed, and the volume of the solid dry ice does not change.
2.00 moles of a gas occupies 62.2 L at a par- ticular temperature and pressure. Its density is 0.900 g/L. What is the molar mass?
students performed acid-base titrations. Redox reactions can also be used in titrations. An example is the titration of ascorbic acid (H2C6H6O6) in lemon juice using triiodide (I3-). A starch indicator will turn the solution blue-black at the endp..
