How do you determine number of rings, double bonds, or triple bonds from degrees of unsaturation? For example a substance C8H8 has 5° degrees of unsaturation, so determine the number of rings and double bonds?
The unit cell of a crystalline material containing Ca, O and Ti can be described as follows. The unit cell is face-centred cubic, but with Ca atoms occupying the corner positions and oxygen atoms occupying the face positions.
Phosphorus pentachloride is used in the industrial preparation of organic phosphorus compounds. Equation 1 shows its preparation from PCl3 and Cl2.

If units were explicitly specified for Kp of the reaction above, they would be [atm]n. What would be the value of n for this reaction?
Calculate kp given that the initial pressures of nitrogen are 95 atm and 80 atm, respectively, and the equilibrium pressure of nitrogen oxide is 6.0 atm. I know the answer is 5.1x10^-3. I am trying to find how is that number possible.
Consider the exothermic reaction A(g) + B(g) C(g) + D(g). Would you expect the addition of heat to lead to the formation or consumption of A(g)? Why?
a Balanced reaction equation must have the same number of atoms of each element on both sides of the equation. to verify that the equation is balanced, count the otoms of each element on both sides of the reaction
