Answer:
A) Age!! Its because even if the object was 1 year old or 100 years old, nothing about the impact would change. However, those other categories depict features that would definitely make an impact. For example as object that is big, fast, and hits at an angle perpendicular to whatever it is moving towards, the impact will be very lage. But if its the opposite and it was small and slow, then the impact crater would not be as large. Good luck on your quiz!!
B because it’s got the least connections
This is a two step step reaction as shown below,
Step 1: Epoxidation of Alkene: In first step Cyclohexene is treated with peroxybenzoic acid in the presence of Dichloromethane which results in the formation of epoxide moiety.
Step 2: Nucleophillic Substitution Reaction: In second step the epoxide formed is treated with Sodium Methoxide which acts as a nucleophile and attacks the less hindered carbon of epoxide resulting in the formation of final product as shown below.
I want to say 8 but i'm not sure. I just did a lesson on this and my notes say it could be 8 but then again I'm not sure.
The element that has the lowest mass per nuclear particle and therefore cannot release energy by either fusion or fission is the element Fe or iron. Iron is referred to as a special element due to its nuclear binding energy. A general idea is that you can have nuclear fusion of two elements and get a heavier element only up to the element iron in the periodic table of elements and also you can only have fusion reactions starting from the element next to iron. This is due to the nuclear forces and the electromagnetic force being balanced for the element iron.
