What is the mass in grams of each of the following: a) 4.50 x 10^12 atoms Cl b) 8.42 x 10^18 atoms of Br

**geometry**

yes a is false

**geometry**

No because that would be three different lines connecting each point not just one straight line through them all it wouldn't work out

**geometry**

Its a because a line with just one point is called a ray and it starts from the point and it extends forever (so thats one point and a line)

**geometry**

haha are you in geometry any more? Im in algebra 2 and its almost exactly the same as algebra 1 so its pretty easy

**geometry**

haha right I thought geometry was hard for a while but than it got easier =]

**chemistry**

If I remember correctly, the higher the temperature, the density will be less. If it is warmer the molecules/particles move faster and produce more collisions. More collision and movement mean less stability for the object overall. And vice versa: cool temperature will mean le...

it wont let me post my answer for you

**Physics Again**

Ok, so I came up with part an answer for the question I posted, hoping that someone can compare with me. I..this is what I did.... found the displacement of car before red light, time it takes for the car to accelerate to its velocity, after the red light, the time of the car ...

**Grammar**

mhmh well I would say yes then, because to me it makes me think about your writing and why you write that way. Which, in my opinion is one thing that you want the marker of this narrative to catch on to. I would ask your prof. or teacher if you have a chance before handing in,...

**Grammar**

You would have to wait for someone else to answer this, but my guess would be that the did is there to emphasize the try. As to if this allowed in essays? I'm not sure, my guess would be no, but maybe I'm wrong. In poerty this would be acceptable:)...also is this an ex...

**PLEASE**

It is called physics (12)....I posted again up and I dont remember what I called it, but I showed the parts I used in it...but there is something I dont have to solve for the final answer (I think)

**PLEASE**

PLEASE SOMEONE RESPOND TO MY QUESTION: Physics (12)! THIS QUESTION IS DRIVING ME NUTS!!! I DID THIS 7 DIFFERENT WAYS!!! I AM SO LOST! PLEASE! I NEED THIS QUESTION FOR TOMORROW!!!! P.S. thanks so much....very much appreciated!

**Science**

lol I sort of figured out my question lol but thanks! I am hoping that someone will be able to tell me if there is something I missed, which I am sure I did. But its ok that its not understandable, high school physics does that to yah!:)

**Science**

lol ok...so bascially, science changes as technology changes. When one thing changes, it allows for crazy ideas to become real. So, New technology allows for new things to be made, and for old ideas to be changed (because new technology allows us to study older methods and cha...

**Science**

oh sorry! should I make it more simple? :)

**Science**

Because biases sometimes leave out necessary things. A bias means the article is only one sided (most of the time). You need to pick out what sounds like it is the author's opinion, so you can decided for yourself if it is the same opinion you have. Or, if things were left...

**Science**

haha no problem!

Science changes as technology adavnces. With new advancements comes new technology, New technology means new ideas, and with new ideas, things change. Years ago there were no such things as cancer treatments. Now, technology has changed which means new things/materials/drugs/t...

well I have to leave now, so I will repost later, if I cant figure it out... Thanks anyways I appreciate,, and besides I got to help others this site, so though I cant get my question, my time was fulfilling!

:) , well I did my question in parts, trying to find what I didnt have....I found: 1.) displacement of car before red light 2.) delta t of car before red light 3.) delta t of car after it accelerates 4) total time of car & train moving (which sounds wrong) 5.) total displaceme...

**We don't do YOUR WORK**

I agree, I hate people who get others to do their work! Which, is why I am appologizing! I think the question I posted made it sound like I wanted you all to do it for me...I posted again by the way. But seriously, I agree! This is the first time I have ever done anything like...

**We don't do YOUR WORK**

WOW! WRONG! If someone gives you the answer, how do you learn how to do it for yourself? What happens when you come to the test or quiz, or even the final exam! You can't expect someone to do it for you. It's called homework help NOT do my homework for me. Trust me, I ...
