use your conversion factors to determine grams to mols and then use mols of cl- per solution to convert

To find the percent you add up all the numbers 5+6+7+12+...then whatever number you get is the denominator. So if you want to find the percent of rats you take 12 divided by all the numbers added together. To determine the degrees of each part you can divide it into 4th which is 25% and then work up or down from there.

Can someone tell me if I am right?

y' = 60(3x + 1)^19 y' = 60(3(0) + 1)^19 y' = 60(1)=60 Then use point-slope form y - y1 = 60(x - x1) y - 1 = 60(x - 0) y - 1 = 60x y = 60x + 1

Why doesn't it enter the reaction?

Ok, first you integrate the problem so it equals 19x + x^2 - 5x^4 Next I'll write this out then show you. You then plug in x = 3 to this equation and then plug in x = 1 Subtract the equation of x = 1 from the equation x = 3. (19(3) - (3)^2 - 5(3)^4) - (19(1) - (1)^2 - 5(1)^4) = -354

Thank you, I can tell which sentence is written correctly, but trying to figure out the pronoun reason is a little confusing to me. I will research some more.

do you know which equation to use? i have no idea what to do!

thanks that helps. so how would you solve it for the other listed values?

Thank you I forgo about checking the answer

THNX.:D

How do you determine the moles of just NaCl? and is the moles of HCl and NaOH just the molar mass? Thanks

kewl

how?

Pitch is to make a plane descend or climb. The pilot adjusts the elevators on the tail to make a plane descend or climb. Lowering the elevators caused the airplane's nose to drop, sending the plane into a down. Raising the elevators causes the airplane to climb.

Okay, sorry....I posted it again correctly :)

:) Thanks you so much! :)

is 1/2 2?

Is it b

So no?

Would it be 43.75g

I meant 443.75 g, would that be correct

Or would it be just 35.5 grams in Cl?

What do I put my answers in? So the anwser will be 14*8??

Y=32 x=8

See above what?

6950*.105=525 is this correct?

yes

Thanks, I was close! I'm not that good with plotting graphs.

@writeacher ...i'm still confused.

Thanks

Would I use cosine or sine?

How do I find omega (ω)?

I got frequency: 2pi/√ 2 Period: √2/2pi

yes thank you!

awesome thank you so much...! :)

awesome.. I wasn't sure about the negative sign..:)

thx

is a =-6.75DS?...

I know, but wanted to be sure about the let statement, equation parts they were asking for. Thanks.

Ok.. Can u check these for me too please? Rename each repeating decimal as a fraction in lowest terms. Using let statement, an equation, a proper solution (using properties of equality) 1) 0.87 (repeating nos are 87) So.. Let X = 0.87 100X = 87.87 - X = 0.87 ____________ 99X/99 = 87/99 X= 29/33 2) 0.5406 (repeating nos are 06) So... Let X = 5406 10,000X = 5406.5406 - X = 0.5406 ________________________ 9999X/9999 = 5406/9999 5406/9999 = 1802/3333 X= 1802/3333 3) 0.048 (repeating no is 8). So... Let X = 0.048 1000X = 48.8 -100X= 4.8 _______________________ 900X/900 = 44/900 X=11/225 4) 3.274 (repeating nos are 74) I really don't get this one

Sorry I repeated these question to you because I forgot to add there are repeating numbers or ellipsis.

Reiny ...Thank you so much for your helpfulness and kindness. Goodnight...

Reiny, do u think 1st question about blankets should b written differently? For e.g. If we say b= 5, then the first part of the equation will equal 175+ 5= 80. I'm thinking it should be written as this: 25 (7+b) = 300 175 + 25b = 300 25b = 125 Pls let me know what you think. Thanks!

How many 2s are there in 7

Sorry meant rational number?

1) 3r + 5 _____. + 2 = 12-2r 2 Find value of r

can u please tell me the number of molar mass i was using...

What is w? You can use e, pi, and M in your response. Please do not subtitute 6 for M.

In Problems 1 to 5 we will work through example of QFTM for M = 6. Problem 1: What is w? You can use e, pi, and M in your response. Please do not subtitute 6 for M. Specify the probability amplitudes. You should use w to denote ƒÖ, but please fully simplify your answer such that you only use ƒÖ and ƒÖ2 and no higher-degree terms. Problem 2: What is QFT6 of 1/ã2(|0> + |3>? Problem 3: What is QFT6 of 1/ã2(|1> + |4>? Problem 4: What is QFT6 of 1/ã3(|0> + |2> + |4>? Problem 5: What is QFT6 of 1/ã3(|1> + |3> + |5>?

Got this result for above question: exp(2ðji/M)âj However it is graded as wrong, can someone help?

exp(2piji/M)beta j

What is w? You can use e, pi, and M in your response. Please do not subtitute 6 for M. Got this result for above question but it is graded wrong, can someone help? e^i*pi/3

Thank you! Did somebody figure out one or all of the QTF6 questions?

Thanks Anonymous and Gyanno! Anyone got Problem 3, 4 or 5?

Help for Q. No 6

6 then I will help with 5, 9 and 12

Leave it.. Its not good to discuss exam questions outside. I don't know how i reached here.. i just realized i don't need course certificate, if I'm not worth it. So, I will try to solve it myself. You do too.. :)

Convection

How do you know that the NaCl has 100 ml. How much volume does the water which is also a product have?

0.04m + F = 12

1.a 2.d 3.d

Thanks for your help

Oh ok I understand now so I would say 1.a 2.a 3.c

I think d because a broadcaster uses a microphone

sorry, didn't mean to post twice lol computer glitched XD

paired test hard

Please can someone help?

i think that 1. They could trade the things they dig, find and then sell it. 2. They could make materials from the trees they find, etc., and sell them.

thx, but what about the land?

4x+2=3x+9 Move 3x to the other side so it will become -3x ( 4x-3x) same with the constant number ( 9-2) . Just combine the constant and the number that has coefficient. Solution: 4x+2= 3x+9 4x-3x=9-2 X=7

I ended up with the wrong answer can I ask what I did wrong? So I got the dHrxn which I found to be -1,679.54 I then determined the limited reagent was indeed F2 and that it produced .1 mol of CF4 I then divided -1,679.54 by .1 to get -16,795.4 and converted it to kilojoules to be 16.8 (sig figs) but it was not right.

Thank you I ended up solving it right after I posted this. I wasn't factoring in the mas of the rod.

This is still not correct. I do not know what I am doing wrong

14. D 15. B 16. D 17. A 18. A 19. C 20. D

so 14-17 is wrong ?? and if so can you help me because i did read my book i mean read i couldn't find it and i am a A an B Enroll student so can you please help I need help.

Is 17. D

is 16. C

i know 16 is A and is 14 B or A

is the answer A

No aneer

help please... im so stuck.. i need help...quickly

so how many large cupcakes would that be?

it would be 62... for the people looking for the answer.. your welcome.. i care

i think its france (several other sources say france)
