A sample of unknown hydrate of FeCl3 weighs 8.693g. After heating the sample to constant mass, the remaining anhydrous salt weighs 5.216g. What is the experimental formula for the hydrate?
One reason you do this is to help minimize the potential side reaction that forms byphenyl. How does the additional 30 mL of anhydrous diethyl ether minimize the formation of the biphenyl side product?
Explain concisely why carbon has two electrons in different p orbitals with parallel spins rather than other possible arrangements.
Dehydrohalogenation Prepare styrene (C6H5CH=CH2) by dehydrohalogenation of either 1-bromo-2-phenylethane or 1-bromo-1phenylethane using KOH in ethanol.
Draw viable Lewis structures to illustrate how the element bromine can take part in an ionic bond, a pure covalent bond, and a polar covalent bond.
Three gases (8.00 rm g of methane, CH_4, 18.0 g of ethane, C_2H_6, and an unknown amount of propane, C_3H_8) were added to the same 10.0 L container.
Volume of added base required to reach the equivalence point? State the pH at one half of the equivalence point
H2S and H2O have simipar structures and their central atoms belong to the same group. Yet H2S is a gas at room temperature and H2O is a liquid. Use bonding principles to explain why.
Diethyl ether C4H10O(l), a flammable compound that has long been used as a surgical anesthetic has a structure
Determine the product of the reaction. As a general rule, a metal will combine with a nonmetal to form an ionic compound.
Describe in brief the risk connected with solutions of 1M NH 3 , 1M HCl, and 1M NaOH?
The imaginary nonmetal E has two isotopes 50E(isotopic mass 49.9715 u abundance 76.66%) 52E (isotopic mass 51.9663 u) Calculate the atomic mass of E as it would appear in the periodic table.
