Multivalent metals (click to advance through paragraphs)

Some metals can have multiple amounts of valence electrons. For example, copper can have 2 or 1 valence electrons and iron can have 3 or 2 valence electrons. There are two ways to differentiate them apart in a chemical formula: IUPAC and Latin

1. IUPAC: In brackets, indicate the number of valence electrons with Roman numerals. E.g. copper(I), copper(II)

2. Latin: Check if the element has a Latin root. If not, use the english root. Replace the end with “ic” if it has the larger charge. If it has the smaller charge, replace the end with “ous”. Make sure it sounds good. E.g. cuprous has 1 valence electron and cupric has 2.

Note: sometimes, the latin root will not sound good with ic or ous. In that case, simply use the english root. For example, mercury has the latin root Hydrargyrum, but the names used are mercuric and mercurous.

Molecular compounds are formed when a non-metal atom becomes bonded with one or more non-metal atoms through the sharing of their electrons. H O

In order for each of the atoms to have a completed valence shell, they must share their electrons, creating covalent bonds. (click to continue slide show)

Nomenclature(click to advance through steps):

1. Name the non-metals

2. Note the number of atoms for each different element

3. Depending on the number above, write in the matching prefixes (see table)

Hydrates

In the simplest terms, hydrates are pure substances which contain water. The water molecule is chemically bonded. This is indicated by the middle dot in the chemical formula. For example, cobalt chloride hexahydrate is: CoCl2·6H20

2. Note the number of water molecules and write the matching prefix.

3. Write hydrate.

which is released when in an aqueous solution. This is like how a hydrogen ion is released when an acid is in an aqueous solution.

The Story So Far…

It is a period of galactic war

between the humans and the

Covenant, an alien species

intent on exterminating our

race. In order to counter their

technological superiority, we

have created the Spartans;

genetically manipulated super-

soldiers. Basically, they’re like

a bunch of Captain Americas in

futuristic armour.

Anyhow, they worked pretty

well, except there were too few

of them, and then one day,

there was a massive Covenant

attack launched on the planet

Reach, where all of them were.

Only the spaceship, the Pillar

of Autumn escaped, carrying

the last surviving Spartan. In

order to lead the enemy away

from Earth, it makes a random

jump into slip-space (kinda like

a worm hole)…

Covenant ships have been always faster than us sir and they’ve been

tracking us since we escaped from Reach.

What? We made a blind jump Cortana, how did they find us

so fast?

Okay then, how do we stand against

these guys?

I’m afraid sir, that frankly, we are screwed.

Very well, bring this ship back into combat alert. I want everyone

in their stations.

Hello Master Chief. It is good to see you. To prevent the Covenant from taking the ship, I will crashland it on the

ring planet below.

Five minutes later…

Your job will be to get out of here as fast as possible with Cortana. Don’t let the enemy get her no matter what, or else they will find out everything about us

Here. Take her and stick her

into your helmet.

Hello Master Chief. We had best get going

Master Chief! I am detecting the incoming approach of Covenant forces. You must find a weapon to defend yourself with.

Hmmm. I have never seen such a weapon before. Looks like it doesn’t even have a trigger.

Hello alien, my name is 343 Guilty Spark. Let’s play a little game. When an enemy is within the range of this gun, it will display some potential compoounds. Only one of them will be correct. If you select it, then your enemy will be vaporized. If you do not select it, then you will be vaporized. Good luck. Muahahahaha.

Okay. I have just hacked into the gun’s computer systems and it seems like what Guilty Spark said is right. Don’t worry about it though Chief. I’ll help you out.

Here they come. By the way, I have synced your helmet with the gun so that it will display the chemical formula of the enemy.

Greetings Master Chief. Thank you for saving us. I have a mission

for you and Cortana.

Hello again. Looks like I won’t be able to help you with combat Chief, but it looks like you’re doing just fine.

From the Covenant’s conversations, I

overheard that Halo is a weapon of some sort and they are trying to find its control centre.

In fact, we should be hovering over the

control room right now. Master Chief and

Cortana, get inside and find as much as you can

about this planet.

Hmmm. I wonder why the Covenant aren’t here yet Sorry Chief. I can’t help you with this one. Guilty Spark has erased all my memory of or related to nomenclature.

I think I could hack into the network if you put me in that slot over there.

Oh dear. You had better get Captain Keyes immediately. Please leave me here

Captain Keyes?!

Your Captain has been infected by a parasite belonging to a species known as the Flood. The other aliens have just released them and are running away like cowards. I need you to find the Index and bring it to the control room right away. These things could take over the whole universe if we don’t stop them.

Okay, so where is this Index supposed to

be?

Keep turning right, and you’ll see a bunch of Flood infested aliens. They are in front of a building called the Library. Inside, you will find it.

Well hurry up and open the door already!

Just take it man. It doesn’t bite.

Back in the Control Room…

No! Don’t do it. It’ll blow up the whole galaxy while it’s at it.

Now put it on the blue thing and it’ll destroy all the Flood there is.Is that true,

Guilty Spark?

Of course it is. How else would you expect to wipeout the Flood?

We can’t activate Halo then. That means, we have to destroy it. The only way I can think of is activating the self-destruct onboard the Pillar of

Autumn.

Well then, let’s do just that.

Later, after much searching and Flood exterminating…

Darn! We need Captain Keyes’ neural implants to activate the self-destruct!

But he’s too far away! Is there a manual way of blowing up the

ship?

Well, a well-placed plasma grenade could probably do the trick.

Hmm. I guess I get to use these Covenant babies after all. Let’s go!

Hey! Not so fast. I cannot allow you to destroy this planet or else the Flood will survive.

Tutorial

Hello recruit. Welcome to Red Dead Reactions. In this game, you will find different types of bombs, which require the use of different chemical reactions to defuse.

Do it right, and you move on to the next stage. Do it wrong, and you die. So first off, you will need to learn about the types of reactions below.

Synthesis

Synthesis

In order to disarm a Synthesis Bomb, you will need to have an understanding of synthesis reactions.Synthesis reactions are chemical reactions in which the smaller reactants (atoms and/or molecules) combine to form a larger product(s).

Identifying a Synthesis Reaction

To disarm bombs, sometimes you will be required to find a matching reaction equation. A synthesis reaction takes the form of:

A B ABA and B represent different atoms and/or molecules.

Note: there can be more than 2 reactants.

Menu

Back

Decomposition

In order to disarm a Decomposition Bomb, you will need to have an understanding of decomposition reactions.Basically the opposite of synthesis reactions, decomposition reactions are chemical reactions in which the smaller products (atoms and/or molecules) are formed from the separation of a larger reactant(s).

In a single displacement reaction, a single element displaces another, hence the name.

Identifying a Single Displacement Reaction

A single displacement reaction takes the form of:

Note: This is when A and B are metals. When a non-metal is being displaced, it’ll look more like A+BC→C+BA. Also, in order for the reaction to happen, A must be higher in the Activity Series than the element it is displacing.

Double Displacement

A double displacement reaction is a chemical reaction in which two ionic compounds(aqueous) “swap” cations to create two new ionic compounds.

ONa CIHH

Compound Compound


This example is also that of a neutralization reaction, a type of double displacement.

Neutralization is when an acid (e.g.HCl) reacts with a base (e.g.NaOH) to produce an ionic compound (salt e.g. NaCl) and water (H2O)
