How do you find the stability of a molecule, for example for NO (nitric oxide)? It would be great if you could explain the bond number and the lone pair number for NO as well.
The melting point of tropylium bromide is above 200 degree C, quite high for an organic compound. How can you account for these experimental observations?
A 60.0 g sample of an alloy was heated to 96.0 °C and then dropped into a beaker containing 87.0 g of water at 24.1 °C. The temperature of the water rose to a final 27.63 °C.
Problem- You need to prepare 100.0 mL of a pH=4.00 buffer solution using 0.100 M benzoic acid (pKa = 4.20) and 0.220 M sodium benzoate. How much of each solution should be mixed to prepare this buffer
For a certain reaction delta H = -76.0 kJ and delta S= -234 J/K, if n=3 calculate E(standard) for the reaction at 25 degrees celsius
degrees celsius was added to an insulated vessel containing 50.0 g ice and 25.0 g water at 0 degrees celsius. What mass of liquid water is present in the vessel at the end?
What total volume of ozone measured at a pressure of 24.0 and a temperature of 234 can be destroyed when all of the chlorine from 18.5 of goes through ten cycles of the above reactions
For the procedure of a certain liquid vaporizing at 1atm, delta H= 55.5 kJ/mol as well as delta S= 74.1 J/mol K. Presume these values are independent of T, Explain what is the normal boiling point of this liquid ignore
Particular solid is soft, a poor conductor of heat and electricity, and has a low melting point. Generally, such a solid is classified as
What is the equilibrium constant Kc for the reaction below. Assume temperature is 25oC. ( Represent the reaction below as a sum of reactions and then combine the corresponding K values to obtain Kc for the reaction below.)
when 0.549 moles of a certain gas fill a balloon the volume is 75 ml. if enough of the same gas is added to the balloon
Draw the boundary surface diagrams for the following atomic orbitals, including the appropiate axes.
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)
