In one of the tests, I tested the solubility of my aq unknown in HCl and NaOH. In both tests nothing happened. The unknown had already been dissolved in H20 earlier(to make my substance aq) , so when i added HCl and NaOH(seperately). It remained the same as before.

What does this imply about the structural properties of my unknown

Is it safe to give credit card information online on chats such as dell chats or even on the phone?

KMnO4 + Na2SO3 + H2O ---> MnO2 + Na2SO4 + KOH

Please use only H3O+ and NOT H+

THANKS:D

KMnO4 + Na2SO3 + H2O ---> MnO2 + Na2SO4 + KOH

I have an exam in few days, and im confused about what room im suppose to be in. The options are

Room 1 (A-McC)

Room 2 (McL-Naq)

Room 3 (Nar-Z)

If my last name starts with MO which room would i be in?

What is the difference between "reality" and "Reality"? How does psycho physics allow us to bridge the two?

In highschool why is the OCA2 gene taught more than the gey gene? Is there any particular reason?

Ive looked everywhere, many convience stores,walmart, and even toys r us. No store seems to carry these cards, does anyone know where i can get them without paying huge prices for shipping from the US.

In all the following problems state the variables or combination of variables which should be plotted to check the suggested variation and state how the unknown may be found ( through the slope and/or intercept of the best fitting straight line y = m x + b). Because you are not given any numerical data it is just required to qualitatively describe you method of solution in few lines with schematic graphs.

The fundamental frequency of vibration of a string is given by where f , ℓ , and T are measured variables. Determine m.

the equation is f= 1/2L ( square root of T/m)

The gas law for an ideal gas is PV = RT , P and T are measured variables, V is fixed and

known. Determine R.

please help, i understand how to get R, but how would i show that graphically?

thanks

im confused b.c isnt temperature directly proportional to pressure. So doesnt this mean that its graph will have a slope of x and volume will equal R. That doesnt make sense.

In an experiment on free fall under gravity the following table is established....(we are given a table)

Let the mathematical model be x=0.5gt^2 and assume that x=0 and t=0

How would we find the value of the constant g, using the logarithmic method. We have to find it from a straight line graph?? im soo confused please help.

57. A rock is thrown vertically upwards with a speed of 12 m.s from the roof of a building that is 60 m above the ground. a) in how many seconds after being thrown does the rock strike the ground? B) what is the speed just before it strikes the ground.

Im confused in part a) as i got the right answer using -60 as the distance. Why is it negative? and then in part b) i used positive 60 and got the right answer. How do i know when its negative or positive?

During an auto accident, the vehicle's air bags deploy and slow down the passengers more gently than if they had hit the windshield or steering wheel. According to safety standards, the bags produce a maximum acceleration of 60g, but lasting for only 36 ms (or less).

How far (in meters) does a person travel in coming to a complete stop in 36 ms at a constant acceleration of 60g?

I got the answer of 0.38 m using the following formula.

x=v0 + 1/2at^2

however im confused, why is the intital velocity 0. I dont understand the logic behind that.

Thanks :D

Hey, im trying to re-learn trig, paticulary grade 11 and 12. Are there any good sites where i can watch videos and learn. Thanks:D

Hey, i have a dell studio 1555 and the grip on the bottom has come off. It has lost its "grippyness" and seems to slide all over the place. Does anyone know where i can buy grip for the bottom of my laptop? Thanks:D

rationalize the denominator

2 root 6 / 2 root 27 - root 8

sorry about the roots, hopefully u guys get it

Can students just download ebooks, bring in their laptops to lectures, and just use the ebooks without paying 100s of dollars for textbooks?

So i grade 10 math, i did horrible as i didnt try at that period of time. I recieved a 52% overall average, with a 67% average in alll my combined courses.

I realized that i need to step up my game, and in grade 11 i recieved 80% in math, and around 82% overall.

And i continued with my studies in grade 12, as i recieved 85% in mathematics, and 81% overall average.

Is this a rare achievement, and should i be more proud of myself, than i am.

Also in grade, i recieved an Scholar award, meaning i obtained an 80+ overall average.
