Discuss the different types of hazardous properties a material can exhibit to be considered hazardous. Discuss five hazardous properties and give one example compound for each hazard.
The procedure uses 3.0M NaOH. However, the student notices that the only solution of NaOH is concentrated (19M ) NaOH solution. How many mL of water are needed to make 500mL of a 3.0M NaOH
Boron nitride, BN, has a graphite-like layered structure in which the layers have eclipsed alignment where the B and N atoms in alternative layers in the direction perpendicular to the layers. Rationalize the difference between this structure and ..
Example: Determine the solubility of calcium fluoride at 25C. And Be sure to note the difference between Solubility and Solubility Product Constant ! What could we do to change the system and produce a precipitate?
Calculate the mass of CuS produced and the concentration of H+ ion produced by bubbling H2S into 1.00 L of 0.10 M CuCl2 (aq) solution. The net ionic equation is:
Calculate the heat required to convert 24.0 g of C2Cl3F3 from a liquid at 12.00°C to a gas at 56.00°C
a metal object with a mass of 19g is heated to 96 degrees Celsius, then transferred to a calorimeter containing 75g of water a1 18 degrees Celsius. The water and metal object reach a final temperature of 22 degrees Celsius. What is the specific he..
Fifty percent of that sunlight is captured by the collector and heats the water flowing through it. What would be the temperature rise of the water as it leaves the collector?
what mass of barium is produced when molten BaCl2 is electrolyzed by a current of 3.30 105 A for 7.00 hours?
A particular coal contains 2.92% sulfur by mass. When this coal is burned, the sulfur is converted into sulfur dioxide gas. The sulfur dioxide gas then reacts with calcium oxide to form solid calcium sulfite
The temperature rises from 19.25C to 22.17C. If the heat capacityof the calorimeter is 98.6J/C, calculate the enthalpy change forthe above reaction on a molar basis
calculate the potential of a platinum electrode immersed in a solution that is prepared by mixing 25 ml of 0.0832 M V2(SO4)3
Gas Nitrous Oxide (N20) is used as an anesthetic and in aerosol cans to produce whipping cream. It is a potent greenhouse gas and decomposes slowly to N2 and O2.
