Answer 1

@quickthing

Answer 2

HI!

Answer 3

Hello. Long time no see.

Answer 4

yes how have you been?
!

Answer 5

i need to know what le charlies principles concetration do

Answer 6

Good, you?

Answer 7

Let me think.

Answer 8

Simply put, Reaction shifts to the right to make more product.

Answer 9

?

Answer 10

LOL. There used to be a guy on here that was great at chemistry. Can't remember his name though.

Answer 11

this is also my study guide lol i need to know what that means

Answer 12

i know a couple

Answer 13

@dtan5457

Answer 14

Let me see, maybe spectrum can help. @Spectrum

Answer 15

Sorry I wasn't as helpful as you.

Answer 16

Its fine

Answer 17

hi spectrum

Answer 18

thanks for the medals

Answer 19

c: thanks for your help c:

Answer 20

Np

Answer 21

Basically this is just the law of balance, but for chemical reaction applications. Not sure what else there is to say.. It basically says that in chemical reactions balance (or equilibrium) will always atleast attempt to be reached. Concentration is just another variable in this that wants to remain balanced.

Answer 22

that is just as fine will you be able to help me with the rest?

Answer 23

i can give more medals :l

Answer 24

i just gotta do that last page

Answer 25

Perhaps. But post them on the openstudy in typed format , my computer is having a tempertantrum. And don't worry about medals, they aren't worth anything.

Answer 26

:o ok thank you!

Answer 27

ok i will post the images

Answer 28

Label the following graphs as endothermic or exothermic:

Answer 29

endothermic means absorbed right?

Answer 30

so it would be the rigth one?

Answer 31

Endothermic is adsorbed yes. So energy in the reaction will be increased. Yes it would be the right one.

Answer 32

OK thank you

Answer 33

my next question is

Answer 34

How do you name covalent compounds?

Answer 35

This type of compound is usually named with prefixes. CO2 Carbon "DI" oxide. The other main rule is that the more negative element second.

Answer 36

more negative?

Answer 37

wow you are really giving me some good examples, i been trying to make this study guide as great as i could

Answer 38

Haha I coulda worded that better, The more positive element on the periodic table is the element named first.

Answer 39

Oh ok which way is postivie in this case the left side to the right side or right side to the left side?

Answer 40

With a few execptions its usually the element thats first From left to right.

Answer 41

thank you! can you help me with another?

Answer 42

Sure.

Answer 43

How do you name ionic compounds?

Answer 44

this is the one from google is it good ? The cation is always written first in the formula for an ionic compound.
Most cations are monoatomic (consist of only 1 atom that has lost electrons to become positively charged) metal ions. ...
The only common polyatomic ion that you will encounter is the ammonium ion (NH4+).

Answer 45

Yeah add onto that another rule really tho. In most examples you will name the metal first.

Answer 46

Ok thank you !

Answer 47

I just have two more they are really easy

Answer 48

OK, as an example for previous think Na Cl or Sodium Chloride

Answer 49

THANK YOU lol yes examples!

Answer 50

How do you find molar mass?

Answer 51

this is on the bottom of each element right ?

Answer 52

Molar mass is usually on any periodic table..its that number that looks like this 77.84 <--- or somethign similar. Its expressed as g/mol of that particular item and is the mass of that element if you have one mol of it. This number will never change as an added bonus.

Answer 53

For example oxygen's molar mass - is around 31.99

Answer 54

OMG

Answer 55

ty

Answer 56

and my last one 7. How do you convert between mass and moles?

Answer 57

Keep in mind oxygen is never found as a single atom and thats why its doubled. But most are just the atomic mass which is on the periodic table. The actual molar mass of oxygen is a special case because its a diatomic element (which means its doubled)

Answer 58

Oh!! atomic mass and molar mass are not the same?

Answer 59

They are almost always the same, my example oxygen being the exception.
Because oxygen will always be paired with another oxygen it's molar mass will be double because a mole of oxygen is technically a mole of (double oxygens)

Answer 60

Ok thats good to know ! I have that one last question

Answer 61

To convert between mass and moles you need to know the molar mass usually. Molar mass tells you how much mass one mole of the substance has. So if you know that and how much of the substance you have, you can determine how many moles you have. Does that help?

Answer 62

Yes it does thank you very much

Answer 63

I can now sleep in peacess!

Answer 64

Alright, have a good rest :D

Answer 65

I have used your exact words on my study guide if you must know

Answer 66

Do i have that permission?

Answer 67

Ok! Thanks you yourself have a goodnight!
