Over to the right of the spill are a number of containers that have been used recently. These containers enclose chemical compounds in solid form that are commonly utilized in your lab. They are- barium sulfite, sodium chloride, potassium nitrite, iron (III) nitrate, sucrose, sodium carbonate, lithium sulfate, naphthalene, potassium permanganate, barium nitrate and copper (II) chloride, potassium sulfite, salicyclic acid.
Thinking the solid is a mixture of chemicals that are generally used in your lab, you require to test the mixture to see which method of waste disposal is correct. Propose a flowchart to test the solid to find out what it might be. The flowchart must obviously state the chemicals needed for each test as well as illustrate the expected test results.
It is possible to make a barometer using a liquid other than mercury. What would be the height (in meters) of a column of water at a pressure of 0.390 atm, given that 0.390 atm is equal to a 0.296 m column of mercury
A curved surface of a liquid which has its vapor pressure at equilibrium with the surroundings has a higher vapor pressure than a flat surface. Why
A 275mL sample of O2 is collected over water at 60 degrees C the total pressure 755 torr what is the volume of O2 at STP?
calculate the delta H for the reaction:CH4(g) + 4Cl2(g) --> CCl4(g) + 4HCl(g). Use the following data: C(s) + 2H2(g) --> CH4(g) delta H = - 74.6 kJ; C(s) + 2Cl2(g) --> CCl4(g) delta H = - 95.7 kJ; H2(g) + Cl2(g) --> 2HCl (g) delta H = - 92.3 kJ
