Answer:
- Elimination
- Elimination
- Zaitsev
- Zaitsev
- Carbocation
Explanation:
- The mechanism is generally accepted to always operate via an ELIMINATION step-wise process.
- The ELIMINATION mechanism process will always produce (after dehydration) a ZAITSEV style alkene as major product
- The driving force for the production of this ZAITSEV style alkene product is generally going to be determined by stability of the CARBOCATION
Elimination mechanism is the removal of two substituents from a molecule in either a one- or two-step mechanism
Carbocation is a molecule containing a positive charged carbon atom and three bonds
Answer : 5100 KJ
Explanation : In the given reaction of
![Fe_{2} O_{3} + 2Al ----\ \textgreater \ Al_{2}O_{3} + 2Fe](https://tex.z-dn.net/?f=%20Fe_%7B2%7D%20O_%7B3%7D%20%2B%202Al%20----%5C%20%5Ctextgreater%20%5C%20%20Al_%7B2%7DO_%7B3%7D%20%2B%202Fe)
we can see that 2 moles of Al is producing -850 KJ of energy
so for 12 moles of Al we can calculate as;
12 moles of Al X
![\frac{-850}{2 moles of Al}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-850%7D%7B2%20moles%20of%20Al%7D%20)
= -
5100 KJ
So, we can say that 12 moles of Al will need -5100 KJ of energy.
Homogenous mixture is a mixture of the "same" , uniform though out. Like mixing salt into water and the salt dissolves.
Heterogenous mixture is a mixture that is not uniform. Like mixing oil and water. You can see the two compounds within the mixture.
1 mole F=19g
2.47 moles F=2.47*19=46.93g
