What is the percent yield of a reaction in which 216 g phosphorus trichloride reacts with excess water to form 134 g HCl and aqueous phosphorus acid (H3PO3)
when cyclopentane is exposed to Br2 in presence of light. Write the formulas of all possible dibromination products. Draw molecule by placing atoms on grid.
A mixture of gases with a pressure of 800.0 mm Hg contains 60% nitrogen and 40% oxygen by volume. What is the partial pressure of oxygen in this mixture?
Write an ionic and net ionic equation for the following reaction between Fe3+ and NH3(aq)
Graphite Furnace vs ICP, with investigating and writing a proposal for Heavy metal testing using Graphite Furnace.
If we assume that the volume change is due entirely to the density change (that is, neglect thermal expansion of the ice/water), what is the difference between the enthalpy change and the energy change during the process? Is this a significant dif..
