This is really weird and I haven't heard of this happening to anyone before but...

I bought a bra from victoria's secret recently. After I bought it and I was leaving the store, their alarm beeped as I was walking out. I dismissed it after the sales assoc. checked my receipt etc. and told me that their systems sometimes make mistakes. Today I was wearing it and I went shopping at a mall. I set off every store's sensor that I walked in and out of. This has never happened to me before. I would bring the bra back to victoria's secret, but I threw out the receipt after I wore it the first time a few days ago. I also paid for it in cash, so there's no record on my credit card. I don't want them to think I stole the bra and I'm trying to get them to deactivate the security in it. When I got home from the mall, I cut all the extra tags on the bra off. Do you think this will stop me from setting off the alarms? Or do you think it's embedded in the actual bra itself?

A battery does 16 Joules of work for every 4.0C of charge that it encounters during a 3.0-second time period. What is the voltage of the battery?

how do you do this?

thanks!

A bus that is traveling at 26.0 km/h, speeds up at a constant rate of 3.6 m/s2. What velocity does it reach 6.8 s later?

find answer in km/h

how do you do this problem?

Thanks mucho!

A car is traveling 23 m/s when the driver sees a child standing on the road. He takes 0.8 s to react, then steps on the brakes and slows at 6.5 m/s2. How far does the car go before it stops?

A race car can be slowed with a constant acceleration of -10 m/s/s

how do you do this problem?

thanks!

Gold(III) chloride, AuCl3, is slightly soluble. It has Ksp = 3.20 10-25. Calculate the molar solubility of AuCl3 in...

- 0.0141 M MgCl2 solution

- 0.0141 M HCl solution

It is known that a maximum of 0.976 g silver acetate (AgC2H3O2) is able to dissolve in 122 mL of water at a certain temperature. This is known as the solubility of silver acetate.

1. calculate molar solubility of silver acetate.

2. Calculate the Ksp of silver acetate at this particular temperature.

Determine the percent, by mass, of KNO3 in the resulting solution.

How do you do this solution concentration problem?

how do you do this solution stoichiometry question?

M= mol

.785 M is .785 moles

find the answer in moles (M)

how do you do this problem?

thanks

I am currently a sophmore in high school, however I would like to start college visits soon (possibly over the summer?) Currently, I have a 4.2 GPA and assuming my GPA stays around the same area, what are some good liberal arts colleges that I should look at? I haven't taken the ACT or SAT yet, as I am a sophmore, but I did take a standardized test called the PLAN test this year and it predicted that I will score a 28-32 on my ACT. I want to look at liberal arts colleges because I am not sure what my major should be, and I think I would like a college that is not really big like state schools. I live in the Chicago area, but I am willing to go anywhere.

I will be turning 16 on february 16th. This also means that it will be my golden birthday. I don't want to have a huge party like you see on "My Super Sweet 16" but I want to do something special with maybe 5 to 10 of my best girlfriends. I live in the chicago area, so if you know any good ideas, activities, restaurants, or anything in the area that would b very helpful.

The balanced chemical equation for the combustion of methane gas is:

CH4(g) + 2 O2(g) --> CO2(g) + 2 H2O(l) ΔH = -891 kJ

Holly runs to the swing set at recess. The swing is suspended from a pole 10 feet high and sits 2 feet above the ground. If her teacher pulls her back and pushes her through an angle of 60 degrees, how far does Holly travel in a back and forth motion?

The heat of reaction is stated for each of the three reactions below.

Fe2O3(s) + 3 CO(g) ---> 2 Fe(s) + 3 CO2(g) ΔH° = -23 kJ

3 Fe2O3(s) + CO(g) ---> 2 Fe3O4(s) + CO2(g) ΔH° = -39 kJ

Fe3O4(s) + CO(g) ---> 3 FeO(s) + CO2(g) ΔH° = +18 kJ

Use Hess's law to calculate ΔH° for the following reaction.

FeO(s) + CO(g) --> Fe(s) + CO2(g)

I know how to solve these kinds of problems but for some reason i am stuck on this one! What is the answer to this problem?

my info:

initial mass of candle and index card: 57.29 g

final mass of candle and index card (w/ all wax drippings): 86.94 g

change in temperature of water: 18.2 degrees celcius

amount of heat gained by water: 7729 Joules

molar mass of candle: C22H46

how do you do this? Thanks so much!

A 4.55 g nugget of pure gold absorbed 271 J of heat. What was the final temperature of the gold if the initial temperature was 24.5°C? The specific heat of gold is 0.129 J/(g·°C).

Find in degrees Celcius. How do you do this problem?
