When lithium metal is heated strongly in an atmosphere of gaseous nitrogen, the product formed contains 59.78% Li and 40.22% N. Determine the empirical formula of the compound.
Construct a titration curve of pAg vs mLs of titrant(AgNO3). titration of 25ml of 0.044M KBr with 0.05M AgNO3. calculate pAg after addition of 0.10, 0.50, 1.00, 5.00, 10.00, 15.00,20.00, 21.00, 21.50, 21.90, 21.95, 22.00, 22.05, 22.10, 22.50, 23.0..
Predicting nuclear stability is important when determining whether or not a nuclear reaction can take place spontaneously.
Do the same for halogenation of an alkene -- as review. Now we do not have HBr as a product. Explain why not -- in terms of balancing the reaction, especially from the standpoint of H atoms.
1.compare and contrast covalentionic and hydrogen bonds.2. what information can you gather from the periodic table.3.
What are the origins of these signals? Why does the spectrum contain two other signals of roughly equal height? What are the origins of these signals
1) Prions are smaller than viruses, which are affected by radiation. 2) Prions do not contain genetic information, which is affected by ionizing radiation.
A sample of gas has a volume of 1.55 L at 35 °C and 1.05 atm. What is the pressure (in torr) if the volume changes to 1.38 L and temperature to -28 °C.
Luminol is a reagent used to detect blood at crime scenes. A technician prepares a stock solution by adding 6.0 g of luminol (molar mass=177 g/mol) to 50.0 mL of H2O.
In the laboratory experiment, as the 4-methylcyclohexene and water are being formed, they are constantly being disstiled from the reaction mixture into a separate receiving flask. Explain how this process helps the reaction proceed with a higher y..
If 8.0 moles of the gas A is placed in a 60.0 L tank with 1.0 moles of B at 0 degrees celsius and 1 atm, they react according to the equation. 2A(g) + B(g) ---> 3C(g) + D(g) How many moles are present in the tank when the reaction is complete
Predict what will happen and check your predictions. Change the styling so that instead of the color changing the link becomes bold when you hover over it. (You need to use the font-weight property.) Why does the white background extend to the end..
3-methylbut-1-ene ---->3-methyl-2-butanone. For the reagents I put, HBr, Tert butoxide, O3 and dms. I was wondering about the O3 and dms, im not sure if that part is right.
