Research into the thermite reaction (displacement reaction) used in the welding of rail tracks. Write out the equation and identify where REDuction and OXidation occur. You should also be able to explain why this reaction is suitable for joining train tracks together.

Answers

Answer 1

Answer:

See explanation

Explanation:

The thermite reaction is a redox reaction that is very important in metallurgy. The reaction is as follows;

2 Al(s) + Fe2O3(s) --> 2Fe (s) + Al2O3 (s).

In this reaction, aluminium is oxidized from 0 to +3 oxidation state while iron is reduced from +3 to zero oxidation state from left to right respectively as shown in the reaction equation above.

This reaction occurs at high temperature and as a result of this, it can be used to join metals at such high temperature. This is why the reaction can be used to join rail tracks.

Read the excerpt from Through the Looking-Glass by Lewis Carroll.

“I won't be introduced to the pudding, please,” Alice said rather hastily, “or we shall get no dinner at all. May I give you some?”

But the Red Queen looked sulky, and growled “Pudding – Alice; Alice – Pudding. Remove the pudding!” and the waiters took it away so quickly that Alice couldn't return its bow.

However, she didn't see why the Red Queen should be the only one to give orders, so, as an experiment, she called out “Waiter! Bring back the pudding!” and there it was again in a moment like a conjuring-trick. It was so large that she couldn't help feeling a LITTLE shy with it, as she had been with the mutton; however, she conquered her shyness by a great effort and cut a slice and handed it to the Red Queen.

Compare and contrast the characters of Rowan and Citra up to this point in the book. How do their character traits make either of them a better fit for being a scythe?

Answers

Answer:

The most notable difference that I remember between Rowan and Citra is that Rowan seemed more absolutely determined, while Citra seemed to carry some determination, albeit with compassion more prominent.  This brings into question the idea of worthiness for being a Scythe - since a Scythe is able to kill people at a whim with no repercussions, perhaps even with praise, should one value compassion or absolute unbiased determination?  Objectively, Rowan is better fit - he is more determined and able to take lives due to his nature.  This will be seen later on in the book if you read what happens to him in the future.  However, as compassion is needed when interacting with others, especially given a difficult idea such as killing, Citra may be a better fit, as she can be empathetic to those who are in the position of being gleaned.

TL;DR: It depends on your point of view.  Both are good candidates, as Faraday asserts simply by choosing them to be his apprentices.
