Use symmetry analysis to generate a molecular orbital diagram for XeF4. As a basis set, consider one σ-bonding hybrid on each F that can be treated the same way as a hydrogen 1s orbital. Ignore the lone pairs/ p orbitals on Flourine.
Now show what additional interactions could occur if Xe d-orbitals participate in bonding. How would this affect the bond order?
The elements X and Y form a compound that is 33.33% X and 66.67% Y by mass. The atomic mass of X is twice that of Y.What is the empirical formula of the compound?
When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag
Determination of the composition of a mixture You will be given a multi-component mixture and will be required to determine (and confirm) the %composition of the mixture, obtain a sample of each component and to verify its purity and identity.
A cloud bank moving across the ocean at an altitude of 2000m encounters a coastal mountain range. As it rises to a height of 3500m to pass over the mountains, it undergoes an adiabatic expansion.
What is the pressure in atmospheres in a 50.0L balloon at 25?C filled pure hydrogen gas produced by the reaction of 45.9g of CaH2 with water? ( show all work) CaH2 + H2O ---> Ca(OH)2 + H2
