For the reaction , 2Cr2 + Cl2(g)--> 2Cr3 +2Cl, Ecell is 1.78 V. Calculate E cell for the related reaction Cr3 + Cl--> Cr2 +1/2 Cl2(g)
Gaseous oxygen is held in two separate containers at identical temperature and pressure. The volume of container A is 6.48 L and it contains 0.785 mol of the gas. The volume of container B id 5.78 L. How many moles of the gas are in container B
The electrons in the bonding orbital tend to be distributed between the two atoms. This is because of their tendency to be shared among the two nuclei.
The atomic radius of nickel is 124 pm, and the average mass of nickel is 58.6934 amu. How do I calculate the density of nickel assuming that it is simple cubic, then body-centered cubic, and then face-centered cubic cell structures.
how many atoms is 3.87 moles of lithium? how many molecules is 0.342 moles of phosphorus pentachloride? how many moles
Solid benzoic acid, C6H5COOH(s), is often used to determine the heat capacity of a bomb calorimeter, because the constant volume heat of combustion of this compound is known with high precision: qV = 26.434 kJ/g. When a 2.088 g sample of C6H5COOH(..
The bais set for the Fe atom consists of valence 3d, 4s and 4p orbitals. Determine the symmetries of these orbitals under Oh symmetry. (c) Construct an MO diagram for the formation of [FeH6]4- from Fe and the H6- fragment Showing which MOs are occ..
