The reaction between nitrogen and oxygen gases requires the absorpotion of 43 kJ of energy per mole of nitrogen according to the following chemical equation,
N2 (g) + O2 (g) ---> 2NO (g)
How many grams of NO are produced in the reaction if 324 kJ of heat are absorbed by the reaction?
What is maximum light wavelength (nm) to be absorbed for creating electron-hole pairs in semiconducting material cadmium telluride (CdTe)? CdTe has a band gap of 1.44 eV.
The rate at which equilibrium is established depends on the rate at which collisions occur. Estimate the number of collisions/(m3 s) among all molecules of air at 1.0 atm pressure and 0 C.

For a given reaction, which of the following statements can be made about the value of the equilibrium constant? It always remains the same.
Which of the following elements will have the same number of core electrons as P?
An unknown salt is either NaF, NaCl or NaOCl.When 0.050 mol of the salt is dissolved in water for form 0.500 L of solution, the pH of the solution is 8.08.
Assume you dissolve 0.235 g of the weak acid benzoic acid, C6H5CO2H, in enough water to make 3.00 multiplied by 102 mL of solution and then titrate the solution
Describe how you will separate the following mixture of ions in solution. Include an explanation/rationale of the reagent used, etc. a. Na+ , Al3+, Ni2+, Sr2+
Ammonium carbamate (NH2COONH4) is found in the blood and urine of mammals. At a temperature of 511 K, Kc = 0.056 for the following equilibrium: NH2COONH4(s) 2 NH3(g) + CO2(g). If 10.2 g of ammonium carbamate is introduced into a 0.500 L containe..
Given equilibrium pressure, calculate Kp, When heated, ammonium carbonate decomposes as follows. NH4CO2NH2(s) f/r2NH3(g)+CO2(g)
