This document contains a 40 question exercise on topics related to the periodic table of elements from a course on organic and inorganic chemistry. The questions cover various properties and characteristics of different groups of elements, including alkali metals, halogens, noble gases, and transition metals. The document provides context for an exam by listing the course, program, university, and instructor who prepared the material.
The dingo is a wild dog found throughout Australia with the exception of Tasmania. It has yellow, red, or sandy fur with a black or white muzzle and spots on its legs. The dingo eats small mammals like rodents and rabbits as well as insects and reptiles in the center and north of Australia, preying on European rabbits, rats, mice, kangaroos, geese, and wallabies depending on location. The dingo resembles a dog but is not domesticated.

Πιθανολογείται ότι στη στρατόσφαιρα
γίνεται η αντίδραση:
HO(g)+ Cl2(g)

HOCl(g) + Cl(g) (1)
Να βρεθεί η ΔH της (1) αν δίνονται:

Την πρώτη εξίσωση την πολλαπλασιάζουμε
με το ½ και γινεται:
½ Cl2(g)

Cl(g)
, ΔH1 = 121 kj
Την δεύτερη εξίσωση την
πολλαπλασιάζουμε με το -½ και γίνεται:
HO(g)
½ H2 O2(g)
, ΔH2 = -67 kj

Την τρίτη εξίσωση την πολλαπλασιάζουμε
με το ½ και γίνεται:
½ H2O2(g) + ½ Cl2(g)

Τέλος προσθέτουμε κατά μέλη τις
εξισώσεις που κατασκευάσαμε με σκοπό
να δημιουργήσουμε την εξίσωση (1).
Έχουμε:
HO(g)+ Cl2(g)
●
HOCl(g) + Cl(g), ΔH= -50,5 KJ
Απάντηση: Η ΔH της αντίδρασης ειναι
-50,5 kj
