Explanation:
18. __Double displacement__ 2LiBr + Pb(NO₃)₂ → PbBr₂ + 2LiNO₃
In a double displacement reaction, there is an actual exchange of partners to form new compounds.
The driving condition for this kind of reaction are:
- formation of an insoluble compound called precipitate
- formation of water or any other non-ionizing compound
- liberation of a gaseous product.

19. ___Single displacement___ Fe + 2HCl → FeCl₂ + H₂
In a single displacement reaction, one substance replaces another.
- The replacement of a metallic ion in solution by a metal higher in the activity series than the metal in solution falls into this category.
- The positions of the two elements in the activity series serves as the driving force.

20. ___Synthesis___ CaO + H₂O → Ca(OH)₂
Synthesis is a combination reaction
- This reaction involves the formation of a single product from two or more reactants.
- A compound forms from the union of two or more reactants
- The large and negative heat of formation of the product is the driving force for this reaction.

21. ______Decomposition__ NiCl₂ → Ni + Cl₂
In a decomposition or cracking reaction, two or more product forms from a single reactant.
The breakdown of a compound into its component individual elements or other compounds fall into this category.
- The driving force for this reaction is the high heat of formation of the compound and the extreme instability of the compound.
- A stable compound can also be decomposed on heating and applying pressure.

The main evidence is the redshift of galaxies. This means the other galaxies are moving away from us. The Andromeda galaxy is having a blueshift though, meaning it's coming closer. Another piece of evidence is warmth in space.
Hope this helps.

We can conclude that Einhorn decides not to steal according to the pre-conventional level where as Finkle decides per the conventional level according to Kohlberg's theory.
Explanation:
Kohlberg's theory is explained in three stages:
- The pre-conventional stage where sense of moral is controlled externally by rules of authority figures such as parents and teachers.An action is viewed according to the results obtained after the act.
- Conventional stage is when a person's morals are controlled by authority figures and their positive relation to the society norms.
- Post-conventional level relies on a person's principles and values where some laws are seen as unjust.
In this case, Einhorn recognizes that if you steal, you might end up being caught and punished because it is not accepted by authority figures and could led to punishment. This is stage one. Finkle recognizes that stealing is unaccepted by the law and people in a society should avoid it.This is stage two.
We can conclude that Einhorn's decision not to steal is influenced by the pre-conventional level where as Finkle's by the conventional level according to Kohlberg's theory of moral development.
