Trying to learn more about standard temperature and pressure. Need help with solving the following example question:
Calculate number of moles at STP to 3 significant figures for the following: 1 liter of methane gas at 730 mm Hg and 25.0 C. Give answer as ______ x 10?
What is the molarity of a sodium chloride solution, if 6.62 g of NaCl are dissolved in enough water to make
For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species. For the reaction C2H6(g)+H2(g) 2CH4 the standard change in Gibbs free energy is
Explain why recrystallization, as a general technique, is usually effective at removing a few percent of impurity, even though the solubility (g/mL) of the impurity might be similar to that of the main component.
NO is produced in the atmosphere at moderately low partial pressure by high temperature combustion. What is its fate as cooling occurs? To help address the question, calculate the equilibrium constant at 298 K and 1300 K for each reaction
An object is made up of copper and zinc. The mass of the object is 46.2652g and has a density of 9.25 g/cm^3. What percentage of the object is copper. What percentage is zinc
Combustion reaction, A fuel has the following weight percentage composition, C = 52%, H = 11%, S = 0%, O = 9%, moisture = 13%, Ash = 15%
This entire mixture is then diluted to 1 liter with water. What is the final concentration of phosphoric acid
What is the Molarity of Phosphoric acid stock used to make 750 ml of dilute 4 N soludtion if 52 ml of concentrated solution was use
when the cations Na+ K+ Cs+ are combined with chloride ion in the gas phase to form ion pairs, which pair formation releases the greatest amount of energy? KCL or RbCl, or NaCl or CsCl.
The normal boiling point of bromine is 58.8 C. Given that the vapor pressure pressure of bromine is 75.0 torr at 2.5 C, Calculate the molar enthalpy of vaporization of bromine.
