I have 11.2 L of a gas at stp. I need to use the molar volume to find how many molecules are in that gas.
Suppose that lysine is dissolved into a buffer to a concluding concentration of 1 mM. Into this buffer, 80 percent of the lysine's side-chain amines are protonated. Determine the p
Q. Show the broader classification? A broader classification is based on the reaction of the oxide with water. According to this, oxides are classified as' acidic, basic, neutr
The oxygen of the hydronium ion The oxygen of the hydronium ion has approximately tetrahedral geometry and is therefore sp 3- hybridized. Two of the sp 3 hybrid orbitals conta
The bond energy of an O- H bond is 109 kcal mol 1. When a mole of water is formed from H and O atoms, then 218 kcal is released. Two O-H bonds are there is H2O so 2*109 kcal an
The frequency corresponding to transition n= 2 to n =1 in hydrogen atom is: (1) 15.66 x 10 10 Hz (2) 24.66 x 10 14 Hz (3) 30.5
