ok. all of that helped alot. i will be sure to post up my paragraph as soon as im done :)

Thanks a lot, though i wanted to find a word that had that w sound in it. tWelve but I don't think there are any so I will use this. Thanks again Guru-MC

ok. so "breaking of charity" could definitly destroy a community...

ok i'll make the changes..thankyou:D

Ok. Thank you. So far I'm at the fact that animals do not have any rights, but that they are protected under our laws against abuse and neglect. They should not be given any rights because even though they are sentient intelligent beings, they do not have...

oh also, that i don't believe in animal rights, so much as I believe in animal wellfare. I'm curious, how are animals not part of the moral community, when they are a part of the human community and interact with us on a daily basis?

Ok. Now, I've never really written an essay before. And I was never taught (high school was a joke). So I'm not sure how to get started with this. And when I looked up on google and other sites how to do this, I was still confused. Any advice?

THANK YOU!! SO MUCH!!!! :) :) :)

Oh and how about the thesis being: While animals lack of cognition denies them acceptance to humanities moral sphere, their status as living creatures prevent us from treating them in a completely unjust manor.

ok. how about... while society does not view animals as having cognition, therefore placing them outside the moral community, they still do belong and are involved with the human community.

shouldn't it be 13/25 and then multiply by 100?

that's true. Animals do have cognition, but they don't have all aspects of it. They think more instinctively than planning for the future.

so it would be Michael has lived in Portland, Oregon; San Francisco, California; and Providence, Rhode Island.

Yes I'm covering all three areas. haha I know. That's one of my points for this paper too.

Ok. How about...: Students should not be discriminated against other students based on their family's social status and income.

20.0% acetone 18.0% Ethyl Alcohol 62.0% water You take the mL you're trying to find divided by the whole solution, then multiply by 100. For example, you have 50.0mL/250.0mL = 0.20 Take 0.20 x 100 and it will give you the percent.

I found this answer, thank you :)

Solved, Nevermind.

Our work is online, and I tried to enter it as 2.03E21 and it would not accept it. It only accepts the answer if everything is correct. Thank you :)

Than you can be the one to tell my prof that, sir :)

Oh! Thank you :)

Thank you Dr. Bob.

What would the Ka for this be?

Oops, sorry. I understand now, thank you.

Use the density of water as 210*10^-6 so (210*10^-6)(0.5*10^-3)(90-19) = 7.455*10^-6 or 0.000007455

No- It would be: Her coat is different from that of her sister.

The "that of" makes the sister possessive- no need to be possessive twice.

I think that the apostrophe would be redundant

The mice would be half heterozygous for black, and half white.

Most likely the one with the most descendants. Evolutionary science generally deals with the passing on of genes, and that frog would have reproduced the most and would therefore have been the most successful.

Sorry, our answers posted at the same time. I didn't mean to seem excessively insistent.

To find the y-intercept, plug in 0 for y and solve for x. 0=2x+2 2x=-2 x=-1 (0,-1) To find the x-intercept, plug in 0 for x and solve for y. y=2(0)+2 y=2 (2,0)

First, find the greatest common factor of the two terms- in this case, 21. Then divide each term by the GCF. 42q/21=2q and -21/21=-1 So, 21(2q-1)

At the first point where he stopped and measured the pH, the H+ ion concentration is 1*10^-5 and the OH- ion concentration is 1*10^-9. This is as far as I've gotten, I can't figure out what to do with this information.

I plugged those numbers into the HH equation and came up with 2.22*10^-5 for the Ka. Does that sound right?

I've calculated the molar mass as 82g/mol, but I can't figure out how to get the dissociation constant.

Yes, the intrepid hero post was mine- these are both extra credit problems from our class and I'm having some trouble with this unit. For that one the Ka I came up with was 2.22*10^-5. As for this problem, your logic makes sense but I'm unsure how to calc...

...H2A->...H+..+..HA- ...x.......0......0 -.00708..+.00708..+.00708 x-.00708...00708...00708 K1=.017=(.00708)^2/x-.00708 x=.01 The acid is .01M. There are 250 mL. There are .205g of acid. .205g=.0025mol .205/.0025=82

It's actually 4.5*10^-6. 5=pKa+log(10/22.22)

The calculated Ka in one of my previous comments is from a different question- it's not related to this problem.

Oh yes! I figured it out by myself.

How to know their mass? Is is their molecular mass?

Thank you so much!

Appetite is not linked to A. physiological hunger. B. the time of day. C. the aroma of food. D. the taste of food. B ?

I had the exact same question.

Then the answer is C.

Thank you for your help.

I don't know if Annika’s 3rd guess is right but from your link I think 2 is D like she said

Is is C because I read on the link that there is a comma in the coordinate adjectives and is Annika’s guess on 3 right?

I chose 3 on B because in my definition it said “too hasty” and hasty means with speed or urgent and- Oh. It’s not C It’s B now cause hasty means with speed and that leads to rash so it’s B.
