1. Calculate the mass percent of a solution that is prepared by adding 61.3g of NaOH to 492g of H2O. 2. Calculate the mass/volume percent of a NaCl solution in which 124g of NaCl is dissolved in enough water to give a total volume of 2.08L.
What happens to the pattern if we try to determine which slit the electron goes through by using a laser placed directly behind the slits
Explain Net Ionic Equations and Balancing, These are only eight out of a fifty-three question hand out, but with eight answers to reference off of I think I'll be far more successful in my attempts at this.

Cobalt was used as an internal standard to analyze a sample of titanium with atomic absorption spectroscopy. A mixture was prepared by combining a 5.50 mL Ti solution of unknown concentration with 2.00 mL of a 13.4 g/mL solution of Co
A 0.325 mol sample of PCl5(g) is injected into an empty 4.15 L reaction vessel held at 250 °C. Calculate the concentrations of PCl5(g) and PCl3(g) at equilibrium.
The electron is passed down an electron-transport chain, at the end of which NADP+ is reduced. The reduction potentials of P700+, A and NADP+ at pH7 and 25 oC are 0.490V, -0.900V, and -0.350V respectively.
The enzyme catalase catalyzes the decomposition of hydrogen peroxide. The following data are obtained regarding the rate of reaction as a function of substrate concentration.
The thallium (present as Tl2SO4) in a 6.05-g pesticide sample was precipitated as thallium(I)iodide. Calculate the mass percent of Tl2SO4 in the sample if 0.235g of TlI was recovered.
A solvent for an industrial process requires the use of phenol or benzene. Both are about the same in effectiveness for the process, and of course, gloves will be used when handling either solvent
