Standard enthalpy of atomization for sodium is 108.4 kJ/mol. Calculate the energy in kJ required to convert 2.11 mol of sodium metal at 25 degrees celsius to 2.11 mol of gaseous Na+ ions. (Ionization energy of Na (g) is 495.9 kJ/mol.
In the reaction below, 3.84 atm each of H2 and Cl2 were placed into a 1.00 L flask and allowed to react: H2(g) + Cl2(g) 2 HCl(g) Given that Kc = 62.1, calculate the equilibrium pressure of HCl.
How would this computed ? compare with the dimensions of a typical atom? (-1 if much smaller, 0 if about the same magnitude, +1 if much bigger)
Impure benzoic acid was dissolved in hot water. the container of solution was placed in ice-water bath instead of being allowed to cool slowly.
An unknown liquid with a boiling point of 58 C at 670 mmHg is soluble in water, cyclohexane and alcohol, what's the liquid.
The half-life of a reaction, is the time it takes for the reactant concentration to decrease by half. For example, after one half-life the concentration falls from the initial concentration to, after a second half-life to, after a third half-life ..
