Combinations of different metals form alloys. An alloy composed by mercury and other metal (or metals) forms amalgam. When a true alloy is formed, the component metals are mixed together at a temperature which is greater than the melting point of all of them.Apr 7, 2017
The purpose of the SN1 and SN2 reactions are;
To study the effect of substrate structure and leaving groups on the sn1/sn2 reactions.
To compare the different mechanisms of nucleophilic substitution (SN) reactions.
<h3>What is nucleophilic reaction?</h3>
We know that in the reaction between an alkyl halide and a specie that has a high electron density, the reaction would involve the attack of a center that has a developing positive charge. The specie that attacks the center taht has the positive charge is called the nucleophile.
We know that the shape of the substrate alkyl halide affects the rate of the reaction or the nature of the nucleophilic reaction. The tertiary alkyl halides tend to undergo the reaction via the SN1 mechanism while the primary alkyl halides tend to undergo the reaction via the SN2 mechanim. The mechanism of the secondary alkyl halides would depend on the conditions of the reaction.

Answer:
Kinetic energy would have to work ten times harder than potential energy.
Explanation:
Let’s say you have a boulder and your asked to push it up the hill it would be difficult right? But lets reverse the situation what if you are asked to roll the boulder down the hill it wouldn’t be much work because the hill is basically doing all the work For you. Hope this Helps:)
