Given the planar trisubstituted cyclohexane, fill in the missing substituents (with H or Cl ) to complete the two possible cyclohexane chair conformations. Then, determine the more stable conformer. You might find it helpful to make a model of the cyclohexane to help visualize the chair conformations. A cyclohexane ring with three substituents, all on wedged bonds. Moving around the ring counter clockwise, there is a bromine on carbon 1, a fluorine on carbon 2 and a chlorine on carbon 3.

Structures in attachment

Explanation:

We can see that when the halogen substituents are in the second conformation, the chlorine and fluorine atoms are closer together and there are van der Waals interaction between these two, given that they are larger atoms than hydrogen. On the other hand, in the first structure the three substituents are away from each other and there are less steric effects, therefore the first conformer is the most stable.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

explanation: no but i do not usually comment
