Please give box diagrams to show electron promotion and hybridization as two stages for AlF3 and C2H6.
Find the mass in grams of PbCl2 in the products. In a test tube you have 1.0 mL of 0.10 M of NaCl mixed with 1.0 mL of 0.10M of NaCl. 2 NaCl + Pb(NO3)2 --> PbCl2 + 2 NaNO3
Using graphical techniques, which form of chlorendic acid (neutral, mono-anionic, or di-anionic) is not responsible for the inhibitory effect
What is the reaction order with respect to chloroform? What is the reaction order with respect to chlorine.
Define a solution contains Ag+ and Pb2+ ions. The addition of 155.0 mL of 1.50 M NaCl is just sufficient to precipitate all the Ag+ and Pb2+ ions. If the total mass of the preciptiate is 32.8g; Define how many grams of AgCl is in the precipitate
For a first-order reaction, what fraction of starting material will remain after 5 half-lives
the density of pure silver is 10.5 gcm3 at 20degc. if 6.17 g of pure silver pellets is added to a graduated cylinder
During the preparation of a solution, a solute is dissolved in a volume of solvent smaller than the desired volume of solution. Subsequently, solvent is added until the final volume of solution is reached
Identify the two important classes of catalysts. Choose a catalyst that exists in the human body. Explain its importance and how it works.
Halogenated compounds are mainly easy to identify by their mass spectra because chlorine as well as bromine occur naturally as mixtures of two abundant isotopes. Chlorine takes place as 35Cl (75.8%) and 37Cl (24.2%); bromine occurs as79Br (50.7%) ..
