Glutamate is another neurotransmitter associated with memory.

So just take 5 mols of water and convert to molecules?

underline a book name and put a poems name in quotes

this is all fine and good, but it doesn't give me what I need to find specific heat. If it helps, I meant heat of formation (delta H f).

How long should an application essay be? (max and min)

where does the temperature factor in? I raised it to 1/2 and got 1.75, but that was not the right answer. (I forgot to mention this, but the first reaction is the original one) Could you put a example up? I am very much a visual learner and need to see it before I can do it.

Is there a good website that has good examples for ap chemistry ranging from easy to difficult?

I already worked out (c), but the rest is still just mush. I'm sorry for my stupidity, but this just doesn't make sense. I can find [H+] or [OH-] as long as I have the concentration of 1 of them, so, ???

By the way, how do you find H+ and OH- concentrations from the pH? I have scoured my text book, but found nothing.

For a.) NH2OH x^2/.50 = 1.1 x 10^-8 => .50(1.1 x 10^-8) = x^2 5.5 x 10^-9 = x^2 5.5 x 10^-9 square root = 7.416 x 10^-5 = x these are all the steps I have

ok. Like here in this example... 1.548937075 x 10 to the 12th. Would you do the problem 1.548937075 x 10 to the 12th which would be 1,548,937,075,000 first before you rounded. I think in the number that I got (1,548,937,075,000) there are 10 significant numbers??

sry... 1.548937075 x 10 to the 12th. round the number to 3 significat figures.

If you didn't do the power of 10 and just kept the number 1.548937075 wouldn't it be rounded to 1.55 if it was round to 3 significant numbers?

Yah, so would you not even look at the 10 to the 12th part of it?

Thanks so much.

238 x360 ----- use a calculator or write it on paper

thanks :]:]:]

yah that's how i was confused

Thank you :]

3x????

thanks, What do you put for the hexagon?

ok thanks so much!

thanks, and also do you know who was king after henry because in my text book it communicates John but i looked on google and it says richard

Henry II of England

Then did John come after that?

So like what are some examples because I was confused and my teacher said it had something to do with Mutualism and Parasitism.

Thanks, do you know of any specific ones that just talk about opposing or just supporting?

Thanks so much!

I found out the answer! also where do guppies live in the world. A website would be great! thanks:)

I got that... disregard this post

ok thanks so much!

ok thanks

I got it!

Thanks:)

where did you get 0.049?

oh so is it incorrect and the answer is 1.2 or is it 1.20? does the second answer have 3 sig figs?

0=6x + 8 +8y is that what the question is? it should most likely be in this format y=mx+b

I think it is beautiful

oh ok. you have to put that into slope intercept form. So it would be 8y=2 (because when we subtract the 3x with the 3x it cancels out) then divide the 8 so y= 1/4 im pretty sure that's how it would reduce down to now you just have to pull your info from that

I don't really understand your question? are you talking about 1st,2nd and 3rd person?

i think it would be chemical weathering

ernest y did u post that on my question? it doesn't ever pertain to my question

What do you mean?

A0 h=12s b)just plug in those numbers for s:)

im not 100% but wouldn't it be Emphasis and Proportion

ok,thanks.. so i got a)810 b)50. c)6.7 is that correct?

thanks

i got 5.76e4 but its wrong

divide -15 by 5. so -3

divide 49 by -7

just to conferm is this the question 4x^2 - 5x ?

I got it wrong! would it be 5e3. cause i messed up on the amount of spaces but idk if that is the correct sig fig?

I got it:) it was 5e2

I got it:)

oops here. When ice melts, it absorbs 0.33 kJ per gram. How much ice is required to cool a 12.0 fluid ounce drink from 75°F to 35°F, if the heat capacity of the drink is 4.18 J/g·°C? (Assume that the heat transfer is 100% efficient.)

thanks!

i have another question: A 43 kg sample of water absorbs 343 kJ of heat. If the water was initially at 22.1°C, what is its final temperature? I got 1.9 but i think i didn't do it correctly

thanks. um. i got 201. but it said it was wrong

how do i know what that mass of the ice is?

oops. forget what I said last

I got it wrong. can u explain it better. i don't think that is in the correct equation form??

Oops I just need c

Oh yah ok thanks:)

I think I got it but why do you say I got my hair cut. Je me suis fait couper Les cheveux? Why do you use me suis?

this is what i have so far: 2AgNO3 + CaCl2 ---> 2AgCl + Ca(NO3)2 for AgNO3: V= 0.100L c=0.0300 mol/L n=cV = 0.03 mol for CaCl2: V= 0.100L c=0.0300 mol/L n=cV = 0.03 mol and now I don't know how to determine the limiting reactant.

Thanks!

Also I have been looking around but not really sure. Can hypochondria be inherited?

so 44.0 kj/1mol X 2.46g? i tried that and got it wrong. am i suppose to convert g to kj?

actualy Kr and Cu. thanks:)

nvm i got it wrong:(

so would it be 2.86?

thanks:)

Im confused, where did you get NaOH?

Thanks!

I keep getting the same thing for b. .17

Thanks:)

Now I just need 3 and 4 checked

I got it I just need help on this one... The gas phase reaction between nitrogen gas and oxygen gas to give NO gas is an endothermic process since 180.8 kJ of heat energy is absorbed when 1 mol of nitrogen reacts with 1 mol of oxygen. In which direction will the equilibrium be shifted if the total pressure is decreased? shifts equilibrium to the right shifts equilibrium to the left will have no effect

So no effect?

is it 6.429x10^-9?

oops... (c) Using the appropriate Ksp value from Appendix D, calculate the solubility of Cu(OH)2 in grams per liter of solution. Appendix D: Ksp for Cu(OH)2 = 4.8 x 10-20

I got A I just need b and c:)

Thanks soooo much:)!

ooooooooo I am liking these quotes. Thankyou Ms. Sue and Writeacher!

That makes sense! Thanks:)

*in them

That's the way I got the answer too. Thank you!!!

thanks!

how about plating?

so is it asking which i don't like?

yes, so just listing 3 things is a triad? you don't need a certain form?

thanks!

Also why is blood and bone considered a connective tissue?

yah they have different lengths and tones of barks

and pitches

for the second problem what is th height??

ohh wait ok that was me just having a dumb moment haha. THANKS sooo much:)

thanks so much! where di the 3/8 come from??

Thanks, so is the degree all of the x added together or jut the greatst one bcause tthen wouldnt 12 be 3 instead of 5?

ohhhh gotcha thanks!!
