• ### Physics electric field!?

Positive point charge q1 = +6.0 x 10^-9 C is at the origin and negative point charge

q2= -4.0 x 10^-9 C is on the negative x-axis at x = -0.200 m. Point A is on the +x-axis at

x = 0.100 m and point B is on the +x-axis at x = 0.300 m. How much work does the resultant electric field of q1 and q2, do on a third point charge q3 = -5.0x 10^-3 C when it moves from point A to point B?

I will love you forever if you can explain how to get this.

• ### Bruise on back/spine?

I have a bruise on my back that runs down the midsection of my spine. I'm in university and sit in those horrible plastic chairs all day. Would I be correct in saying that the bruise is most likely just from sitting in these chairs?

• ### Help with a Calculus question please?!?

SplendidLawn sells three types of lawn fertilizer: SL 24-4-8, SL 21-7-12, and SL 17-0-0. The three numbers refer to the percentages of nitrogen, phosphate, and potassium, in that order, of the contents. (For instance, 100g of SL 24-4-8 contains 24g of nitrogen.) Suppose that each year your lawn requires 500 g of nitrogen, 100 g of phosphate, and 180 g of potassium per 1000 square feet. How much of each of the three types of fertilizer should you apply per 1000 square feet per year?

• ### Neutralization reaction help?

Okay so I'm supposed to find the products of the neutalization reaction for a hydroxide ion and a methylammonium ion, would I be correct in saying that the products would be water and CH3NH2? If not, what would the products be?

• ### Acid/base reaction help?

What would be the products of the following reaction

CH3O-Na+ + HCN ---> ?

• ### Neutralization reaction without water?

Is it possible to have a neutralization reaction without the production of water? For example I was asked to find the products of the reaction between a methylamine and a Pyridinium ion. Any help in explaining this would be extremely appreciated. Thanks!

• ### Do guys find virgins uninteresting?

Okay so here is the deal. I am 19 and I am still virgin and have never been in a serious relationship with a guy. I never thought it was a problem until yesterday when I was talking to a guy who blatantly told me i was "a lot less intriguing" after he found out that I was a virgin. So my question to you guys is, do guys find girls that are still virgins "not intriguing"?

• ### Can you help with a chemistry question?!?

Calculate the entropy change, in J/K, for the reaction below. Assume the reaction occurs under standard conditions.

HCl (g) + NH3 (g) ---> NH4Cl (s)

186.8___192.3_______94.6_____<-- S(J/mol K)

• ### Can you help with a chemistry question?!?

A liquid solvent has a boiling point of 96.8 oC. Calculate the change in the boiling point of the solvent if 0.949 moles of a solute is dissolved in 0.50 kg of solvent. The Kb for the solvent is 1.30 o C/m.

Thanks!

• ### Help with a molarity question?!?

Calculate the molarity of a ethanol solution prepared by dissolving 47.41 grams of ethanol, CH3CH2OH, in 753.7 grams of water. The density of the resulting solution is 1.072 g/mL. Enter your answer to the correct number of significant digits and do not enter units as part of your answer.
