What is the chemical formula of the precipitate that forms when a a aueous solution of sodium chloride is mixed with an aqueous solution of siver nitrate?
Gas diffusion and Viscosity are both transport properties, Derive the general relationship between the viscosity for a gas and diffusion coefficient .calculate the diffusion coefficient if Given that the viscosity of Ar is 223 micro Pascals at 29..
Find the pH solution & Hydronium ion concentration and What is the pH of a solution of 0.17 M acid and 0.81 M of its conjugate base if the pKa = 8.62?
An automobile engine requires a carburetor or fuel inector to mix the fuel with air. The fuel and air must be mixed in a particlar ratio to achieve maximum efficiency in the combustion of the fuel.
Describe how the results from this control experiment would be incorporated into the data analysis to the correct for this error.
A 50.0-mL sample of 0.50 M HCl is titrated with 0.50 M NaOH. What is the pH of the solution after 28.0 mL of NaOH have been added to the acid?
Acetylene gas (C2H2) is produced by adding water to Calcium carbide CaC2. How many grams of acetylene are produced by adding water to 5g CaC2?
Use the three-step method described in the module to predict the actual precipitates which form (if such is the case) when the following solutions are mixed
The determination of iron in industrial waste stream is often carried out by reacting the water sample with o-phenanthroline to form a red-orange complex that absorbs at 510 nm.
The vapor pressure of an unknown compound at 25 degrees C is 94.6 Torr and its enthalpy of vaporization is 30811 J/mol. Estimate the normal boiling point of this compound. assume the enthalpy of vaporization is independent of temperature.
If 4.00 mol of calcium carbide (CaC2) reacts with an excess of water, how many moles of acetylene (C2H2), a gas used in welding, will be produced.
Calculate the quantity of gas, in moles, if 127 L at 55.0 C has a pressure of 11.35 kPa.
