I have already been administered the varicella (chicken pox) vaccine as a child. Now I am going to college and i need to show a record of my varicella vaccine which i don't have because I have lost it for some reason. So I'm considering taking it again just for the record. Is it safe? Would it have any side effects? Can I take the vaccine second time round?

Can someone plz help me out with this. I'm very bad with logs! Whats the value of D?? Just explain how to do it manually, using a calculator or just give me an answer for it. Thanks :)

Not getting the right answer to the following question. Plz help me work it out! Thanks.

The perimeter of a rectangle is 34cm. Given that the diagnol is of length 13cm, and that the width is x cm, derive the equation x^2 -17x + 60=0. Hence find the dimensions of the rectangle.

It is a trigonal pyramid right?

I'm working on my college applications these days and one of my application requirements is to write a CV/Resume. Any tips or advise that would be useful? What do I need to include? Should I include my SAT scores etc? How am I supposed to format it? FYI It's not supposed to be longer than three pages. Thanks :)

How do you say she has a fever in french using the imperfect tense? (imparfait)

I know that using the present tense this is how you say she has a fever:

Elle a de la fievre.

But with imperfect would it be

elle avait de la fievre?

Does avoir always become avait when using the imperfect tense?

Okay so tomorrow I'm gonna be taking the SAT 2 subject tests: Physics and Chemistry (to be more precise)

You know how they reduce your score by 1/4 point if you mark a wrong answer on the SAT...do they do the same on the SAT 2?

I have a paper due in which I use references from a well known play. I am required to use the MLA format for referencing. For example if I'm taking a quote from Henrik Ibsen's play A Doll's House off page 1 of the book which lies in Act One of the play is this how I would use MLA format?

"Quotatation" (Ibsen, Henrik. A Doll's House. Act One, Page One)

where A Doll's House would be in italics.

Am I doing it right? Please correct me if I'm not. Thanks :)

Please make sure its not older than 6 months.

Just include the link in your answer.

Please make sure the article isn't about social networking.

It would be nice if its from a reliable source like the newyork times or BBC.

It HAS to be about networking...can be about the internet too since the internet is a network also.

10 points for the best link :)

I'm doing a chemistry experiment on kinetics and my aim is to find the order of the reaction with respect to one of the reactants(HCl) in the reaction between HCl and Mg. I'll conduct the experiment using different concentrations of HCl. Using a rate-concentration graph I'll be able to find the order with respect to HCl. The question is how do I find the rate experimentally?

I am studying Sylvia Plath's poem "The Night Dances" and I don't really get what she's trying to say. Can you please give me your interpretation, a summary or an explanation about what you think is being described in this poem? Here's the poem:

A smile fell in the grass.

Irretrievable!

And how will your night dances

Lose themselves. In mathematics?

Such pure leaps and spirals ----

Surely they travel

The world forever, I shall not entirely

Sit emptied of beauties, the gift

Of your small breath, the drenched grass

Smell of your sleeps, lilies, lilies.

Their flesh bears no relation.

Cold folds of ego, the calla,

And the tiger, embellishing itself ----

Spots, and a spread of hot petals.

The comets

Have such a space to cross,

Such coldness, forgetfulness.

So your gestures flake off ----

Warm and human, then their pink light

Bleeding and peeling

Through the black amnesias of heaven.

Why am I given

These lamps, these planets

Falling like blessings, like flakes

Six sided, white

On my eyes, my lips, my hair

Touching and melting.

Nowhere.

Here's another multiple choice question I don't get how to do. Please help me out and explain how to do it. Thank you :)

C. 17

D. 19

Sorry about the equation. It might be a little unclear. Hope you guys can make it out.

Here is a multiple choice question about Avogadro's constant that I was unable to solve. Can you please help me solve it and explain how you did it? Thanks :) The question is this :

Avogadro’s constant has the same value as the number of

A. molecules in 1 mol of solid iodine.

B. atoms in 1 mol of chlorine gas.

C. ions in 1 mol of solid potassium bromide.

D. protons in 1 mol of helium gas.

Here is a multiple choice question I couldn't solve:

Which sample has the least number of atoms?

A. 1 mol of H2SO4

B. 1 mol of CH3COOH

C. 2 mol of H2O2

D. 2 mol of NH3

Can you please explain how to solve this question? I don't know how to do the calculations. I'm not getting the right answer. Please help! Thanks! :)

Is the graphical method the same as the parallelogram method? If not, can you please explain how to add vectors using the graphical method?

Here's a chemistry question about the mole concept that I couldn't solve. Can you please help me out?
