1)Use Coulomb's law to calculate the ionization energy in kJ/mol of an atom composed of a proton and an electron separated by 166.00pm 2)What wavelength of light would have sufficient energy to ionize the atom?
Calculate the equilibrium [F-] in a saturated solution of CaF2 and 0.0223 M Ca(NO3)2. Take ionic strength effects into account.
In a certain experiement, 4.6 g Al is reacted with excess oxygen and 6.8 g of product is obtained according to this reaction: 4 Al + 3 O2 --> 2 Al2O3 What is the theoretical yield for this reaction
Based on the half-reactions and their respective standard reduction potentials below, which addition to an aqueous solution containing Fe(NO3)2 will result in a reaction under standard-state conditions?
A paint company mixes it's paint with water to create more paint per gallon. They currently have ten gallon jugs which contain 10% water.
The activation energy for the following reaction is 60. kJ/mol. Sn2+ + 2Co3+ → Sn4+ + 2Co2+ By what factor (how many times) will the rate constant increase.
The first-order decomposition of SO2Cl2 to sulfur dioxide gas and chlorine gas at 320°C has a half-life of 8.75 hr. If one begins with 600. mmHg of pure SO2Cl2 in a 5.00-L flask at 320°C
What is the boiling point of a mixture composed of 85 g HOCH2CH2OH (ethylene glycol) and 125 g H2O? The boiling point elevation constant for H2O is 0.512 °C/m.
what is the likely magnitude of the equilibrium constant K? Hydrogen is used as a rocket fuel because it is very light and reacts explosively and completely with oxygen. For the combustion reaction
At a given temperature, 1.18 atm of F2 and 5.91 atm of Br2 are mixed and allowed to come to equilibrium. The equilibrium pressure of BrF is found to be 1.044 atm. Calculate Kp for the reaction at this temperature. F2(g) + Br2(g) 2 BrF(g)
Assuming that at low pH the principle species in solution is HA and at high pH the principle species is A-, calculate the pKa of the indicator.
Car manufacturers are developing engines that use H2 as fuel. In locations where hydroelectric plants produce inexpensive electric power, the H2 can be made industrially by the electrolysis of water.
