5. Man muss mit Wasser H2O einen Stoffausgleich durchführen, sodass links und rechts des Reaktionspfeils die gleiche Summe der Elemente Wasserstoff und Sauerstoff vorliegt.

1. Atome innerhalb eines Atomverbandes eines Elements haben immer die Oxidationszahl 0. Beispiel: Sauerstoff O2

2. verschiedene Atome: 2.1 Metalle positive OZ 2.2 Fluor F: - I 2 3 Wasserstoff H: + I 2 4 Sauerstoff O: - II 2.5 Halogene: - I

3. Bei Verbindungen ist die Summe der Oxidationszahlen aller Atome 0.

4. Bei Ionen ist die Summe der Oxidationszahlen aller Atome gleich der Ionenladung.

Oxidationszahlen sind eine fiktive Größe, die beim Aufstellen einer Redoxreaktion hilft. Beim bestimmen muss man einige Regeln beachten.

Oxidation ist immer eine Erhöhung der Oxidationszahl eines Elements, Reduktion immer die Reduktion der Oxidationszahl eines Elementes.

Oxidation ist eine Reaktion, bei der Elektronen abgeben werden. Bei einer Reduktion werden Elektronen aufgenommen.

1. Man bestimmt die Oxidationszahlen der beteiligten Verbindungen.

2. Man erstellt Teilgleichungen und bestimmt Oxidation und Reduktion anhand der Änderung der Oxidationszahlen.

3. Man fügt die aufgenommenen oder abgegebenen Elektronen in die Teilgleichung ein.

4. man führt, abhängig vom umgebenden Medium, einen ladungsausgleich durch, so dass auf beiden Seiten der reaktionsgleichung die gleiche Ladung steht. Das muss nicht 0 sein!

Im sauren gleicht man mit Oxonium-Ionen H3O+ aus, im Alkalischen mit Hydroxid-Ionen OH-. hin und wieder wird in schmelzen gearbeitet, dann gleicht man mit Oxid-Ionen O2- aus.

6. Man kontrolliert die Elektronenbilanz. Es müssen genauso viele Elektronen aufgenommen werden, wie abgegeben wurden. Ist das nicht der Fall, wird ausgeglichen, indem man das kleinste gemeinsame Vielfache der Elektronenzahl sucht und die Teilgleichungen entsprechend multipliziert.

7. Man erstellt eine gesamtgleichung durch Addition der beiden Teilgleichungen. Gleiches wird dabei gekürzt.

Bei organischen Verbindungen wird jedes Kohlenstoff-Atom einzeln betrachtet. Kohlenstoff-Kohlenstoff- Bindungen zählen nicht zur Ermittlung der Oxidationszahl, Wasserstoff hat immer +1, Sauerstoff immer -2. Insgesamt muss das Kohlenstoff-Atom mit seinen Bindungspartnern (außer Kohlenstoff) auf die Summe 0 kommen.

You see, my mother was a district nurse until she died when I was 14, and we used to move from time to time because of her work.

Too many ads that try not to go over the reader's head end up beneath his notice.

My vision of freedom is to be yourself.

My soul is more at rest from the tempter when I am busily employed.

Myths are made for the imagination to breathe life into them.

Working lives are for the state to influence. Unemployment makes people unhappy. So does instability.

The only way to stay sharp is to do live shows. There is no part-time comedy.

It's great to want to be part of something, but it's a different thing completely to believe wholly in some type of movement, and to give everything for that something.

Every compulsion is put upon writers to become safe, polite, obedient, and sterile.

If the American public is so into morality in movies, why don't they throw more of their disposable income at religious-themed entertainment? For every 'Passion of the Christ,' there's a 'Fireproof' that comes and goes with no notice.

Today, diabetes is now epidemic, according to the Centers for Disease Control, the National Institutes of Health, the American Diabetes Association and other national healthcare leaders.

If you want something hard enough, it just gets done.

One cannot deny the great role women have played in the world community. My flight was yet another impetus to continue this female contribution.

Home is where you are loved the most and act the worst.

Adelaide is becoming a hub for higher education.

I was hit by a car when I was 13, and the rumour was immediately that I had been playing chicken with the car with my best friend Kenny in front of the Nutmeg Pantry, which was the only shop in Sharon. In fact, the guy who hit me was inebriated.

Of the seven deadly sins, anger has long been the one with the best box of costumes. When the guy in the next car rages at you, he's dangerous. When you rage at him, you're just. We can usually recognize the results of anger, especially in others, as destructive and evil.

I could have been a dancer. I just never got my shot at it.

It's very rare to have rehearsal time on a television show: You get scripts, you show up, and you do it.

At a time when going to college has never been more important, it's never been more expensive, and our nation's families haven't been in this kind of financial duress since the great depression. And so what we have is just sort of a miraculous opportunity simply by stopping the subsidy to banks when we already have the risk of loans. We can plow those savings into our students. And we can make college dramatically more affordable, tens of billions of dollars over the next decade.

I grew up in a drive-in theater, from the time I was 8, working in a snack bar watching four features every week. It was silent theater in the sense that this was a drive-in, which meant that I often saw the films going with no sound. But I learned to tell stories through action.

I love playing. If it was down to just that, it would be utopia. But it's not. It's airplanes, hotel rooms, limousines, and armed guards standing outside rooms. I don't get off on that part of it at all.

My dad used to sing in a quartet. He loved everything: adult contemporary, anything smooth. He'd listen to the quartets.

My mouth has a tendency to get me into trouble, but because I'm so small and I take on people who are lager than me. If someone punched me, I'd get my drummer beat them up.
