Hi,

I am stuck on this hard question.

If you go to Google, google this "net ionic equations for test tubes 4 to 9" and go to the first link. I cant solve #3 which says "write the net ionic equations of any reactions that occurs in test tubes 4 to 9) PLEASE HELP ME

The link is also below.

http://www.google.com/url?sa=t&rct=j&q=net%20ionic...

I have no clue how to do this. can someone help me?

It says"Using Le Chatelier's Principle, predict the direction of the net reaction as a result of increasing the pressure at constant temperature.

a. N2(g)+O2(g) <-> 2NO(g)

b. PCl5(g) <-> PCl3(g)+Cl2(g)

c. CO(g)+Cl2(g)<->COCl2(g)

Thanks

A gas mixture contains 1.24g N2 and 0.79g O2 in a 1.59L-container at 14 degrees C.

Calculate the mol fraction of N2 and O2!

Ill pick a best answer. Please help!!!

How long would it take the same amount of gaseous to effuse from the same container under identical conditions?

I got 20.4 but thats wrong. PLEASE HELP!

A sample of gas has a mass of 38.7mg . Its volume is 220mL at a temperature of 56C and a pressure of 903 torr...

Find the molar mass of the gas.

PLEASE HELP! Ill pick a best answer asap

What the formula equation, net ionic and complete ionic equation? Thanks

What is the reaction for:

sodium hydroxide and lithium sulfate

I need the formula equation, total ionic equation, and net ionic equation.

I dont get this problem! Please HELP :(

A mixture of C3H8 and C2H2 has a mass of 2.2g . It is burned in excess O2 to form a mixture of water and carbon dioxide that contains 1.5 times as many moles of CO2 as of water.

Im getting my first car and looking for a reliable sedan under $25K with under 50K miles. What kind of cars are there in that range?

Im looking at the Lexus IS250, Infiniti G35/G37, and Acura TL....are there any other good ones? Im trying to get a nice car with navigation and leather seats.

Which of those is best and are there others I may have missed?

Thanks

The coefficient of (x-1)^5 in the Taylor seres for xlnx about x=1 is?

PLEASE SHOW STEPS

The sum of the series (there is an E symbol for summation) and it goes from n=1 to infinity of ((pi^3)/(3^pi))^n meaning the pi cubed divided by 3 to the pi power is all to the n power. Please show steps. Thanks

The question says:

"the coefficient of x^4 in the Maclaurin series for f(x) = e^(-x/2) is:"

How do I do this?

I found this on amazon and the reviews seem good:

But I heard that 30% is a lot and it can actually be bad?

What do you guys think...or what should I use.?

Thanks

Hi,

I have the problem:

1/(n(sqrt((n^2)+1)))

Does this diverge or converge?

Because I thought according to the nth term test this would diverge because the limit equals zero because its bottom heavy? But the book says diverge...PLEASE HELP CLARIFY THIS. Thanks

1/(n*(ln(n)^2)

basically its 1 divided by n times (ln(n))^2 The "n" is NOT squared only the ln(n) is.
