The half life of a first order reaction is 13 min. If the initial concentration of reactant is 0.085 M, what is its concentration after 8.2 minutes.
Calculate the standard cell potential at 25 C for the reaction X(s)+2Y+(aq)?X2+(aq)+2Y(s) where ?H? = -651kJ and S = -371J/K.
Magnesium metal is used as a sacrificial anode to reduce the corrosion of underground storage tanks (made of iron, more accurately steel). As a result the sacrifical metal corrodes instead of iron. Explain
hydrochloric acid for neutralization. A 12.0mL volume of a phosphoric acid solution requires 35.1mL of the sodium hydroxide solution for complete neutralization.
the reaction produces 0.90 mol of CO2 and 0.45 mol of H2O. Determine the number of mols of carbon in the compound. Determine the number of mols of hydrogen in the compound.
the temperature inside a pressure cooker is 111°C. Calculate the vapor pressure of water inside the pressure cooker.
Calculate the energy of a photon emitted when an electron in a hydrogen atom undergoes a transition
explain it is important to cerry out the determining the molar mass of a volatile liquid by the dumas method
The nitrate concentration in an industrial effluent is determined using a nitrate ion selective electrode. Standards and samples are diluted 20-fold with 0.100 K2SO4 to maintain consatnt ionic strength.
Show all long pair electionrs (this means even those unreactive lone pairs), proper mechanistic arrows, all intermediate steps, and all side reactions if any. If you write them by hand please write clearly so I can understand everything.
The following density measurements were made on a bar of iron: 7.58 g/mL, 8.02 g/mL, 7.83 g/mL, 7.80 g/mL, and 7.66 g/mL. The accepted value for iron's density is 7.85 g/mL. Find: The error of the average of this set of measurements
Give the cell notation based on the following reaction: Fe(s) + Hg2 ++ (aqueous) = Fe++ (aqueous) + 2Hg (l) the solution concentrations are 0.01 M
