Why is the Beer - Lambert law in units of absorbance rather than in units percent transmittance?
The known metal ion solution used in this experiment contains 0.10 M of each of the six metal ions. What are the initial concentrations of Ag, Pb, and Cl before any precipitation/reaction occurs, but after the mixing (i.e. dilution) of equal volum..
Describe the preparion of 1.00 liters of a 1.00 M acetate buffer, pH 6.00, starting from a 17.40 N solution of glacial acetic acid
A sample of granite contains various oxides of silicon, aluminum, sodium, potassium, calcium, and iron. Each of these oxides gives the granite a coarse-grained texture. Which term or terms could be used to describe this sample of granite?
Excess Ag2CO3 is added to an 0.2 M K2CO3solution. Calculate the equilibrium concentration of Ag+ under these conditions.Ksp for Ag2CO3 is 8.1 x 10-12.
which of these is true about the following reaction?
Pure copper may be produced by the reaction of copper(I) sulfide with oxygen gas as follows: Cu2S(s) + O2(g) ? 2Cu(s) + SO2(g) If 0.330 kg of copper(I) sulfide reacts with excess oxygen, what mass of copper metal may be produced
The question in the lab is asking what percentage by mass is the calcium, chloride and water in the orginal solution for each trial. In this lab we performed two trials, in each, we added 50 mL water to 2.0 g of CaCl2.
The Ksp of magnesium phosphate at a given temperature is 9.78 x 10-17. Calculate the molar solubility at this temperature.
