Explain what is the formula for the complex formed from chromium (III) four moles of water, as well as 2 moles of chloride?[Cr(H2O)4(Cl)2], [Cr(H2O)4(Cl)2]+, [Cr(H2O)4(Cl)2]+3
Give the formula of a product (derived from the first-named substance) that may be formed in the following reactions. (Note, in the example that any lower oxidation state compound is possible: but not any higher one. Some are more probable than ot..
In the titration of a solution of the extremely weak acid, HCN (Ka = 6.2 x 10-10), by a solution of sodium hydroxide of equal concentration,
A solution of Ba(OH)2 is standardized with potassium acid phthalate (abbreviated KHP), KHC8H8O4 (M = 204). If 1.530 g of KHP is titrated with 34.50 mL of the Ba(OH)2 solution, what is the molarity of Ba(OH)2. (A) 0.0217 M (B) 0.0435 M (C) 0.109 M ..
The greater acidity of terminal alkynes as compared with alkanes is primarily attributed to a) the greater electronegativity of sp hybridized carbons compared to sp3 hybridized carbons
carbon tetrachloride reacts at high temperatures with oxygen to produce two toxic gases phosgene and chlorine.ccl4g
How many kilograms of sodium fluoride would be needed to treat a 8.00 x 10^7 gal reservoir
Consider an aqueous solution that is 0.934 M in FeCl2 (MW = 126.752 g/mol) with a density of 1.31 g/mL. Calculate the molality, mass percent, and mole fraction (?) of FeCl2 in this solution. The MW of H2O is 18.02 g/mol.
One mole of H20(g) at 1.00 atm and 100.Celcius occupies a volume of 30.6 L. Explain when one mole of H20(g) is condensed to one mole of H20(l) at 1.00 atm and 100. Celsius 40.66 kJ of heat is released. If the density of H20(l) at this temperature ..
List and draw all types of noncovalent interactions (charge-charge electrostatic, hydrogen-bonding, hydrophobic reactions) that can occur between the side-chains of the following amino acids.
