What would the molecular orbital diagram for a compound made of equal portions of aluminum and phosphorous look like
How would the following modifications of the experimental procedure used in this experiment affect the mass of the precipitate collected? Indicate whether the mass would be greater than, unchanges, or less than that obtained. Briefly explain the ..
A student mixes 5.0 mL 2.00 x 10-3 M Fe(NO3)3 with 4.0 mL 2.00 x l0-3 M KSCN, and 1.0mL deionized water. She finds that in the equilibrium mixture the concentration of FeSCN2+ is 1.2 x l0-4 M.
A 500-g sample of Al2(SO4)3 is reacted with 450 g of Ca(OH)2. A total of 596 g of CaSO4 is produced. What is the limiting reagent in this reaction, and how many moles of excess reagent are unreacted?
consider the reaction of 215ml 2.15M nitric acid with 26.0 g of solid iron(2) carbonate for the following questions 1. write the balanced chemical equation for this reaction 2. which reactant is the limiting reactnat?
What would the appropriate substrate concentration be? b) At what substrate concentration would you expect 30% of the enzyme molecules to have substrate bound?
Calculate the volume and mass required to make 0.1m solutions of your assigned acid (HNO3) and conjugate base
How much heat in kilojoules is evolved or absorbed in the reaction of 244.0g of calcium oxide with enough carbon to produce calcium carbide?
Calculate the solubility product (Ksp) for barium fluoride if the concentration of the barium ion is 3.6 x 10-3 M and of the fluoride ion is 7.2 x 10-3 M.
What must that mean in terms of Light absorption and transmission and in terms of the energy associated with any molecular orbital transitions in indium antinomide?
Biocarbonate ion can react in water to produce hydroxide ions and carbonic acid according to the equation below.
In the early days of the periodic table, the 1870s, both silicon and tin were known elements, but germanium was unknown. Using these trends and the densities of silicon and tin that you just obtained, estimate the density of germanium?
Assume the radius of a neutron to be approximately 1.0; times ;10^{ - 13} {rm cm}, and calculate the density of a neutron.
