This is the same thing as me. I currently interested in some girls, one who is also interested in me. But instead of me to take things further, I'm a little distance and instead prefer to use my...

Thank you, that explained it.

But doesn't f=ma cater for a constant acceleration? You just said that if any resistive forces are concerned (which is mostly the case on earth) then net force will decrease and therefore...

Why does nobody want to answer my question? What have I done?
-
K basically this is F = Ma right?
Isn't this law impractical for any situation outside of a vacuum? If I was pushing a toy car with a constant force 10N in order to make it accelerate, resistive...

Hello I am asked to derive this formula by applying a binomial expansion to the expression for 'gamma factor' (that funny y shaped symbol). To make things clear I will denote gamma as 'y' and beta...

Is it wrong for me to listen to Metal as a Christian? I know there are some bands in the Black & Death metal sub-genres that are openly blasphemous to the Lord God, but bearing in mind I'm aspiring...

I never once said I would rape, kill or harm innocent people. My lust for killing was aimed at Demon's, servants of Satan, and corrupt and evil people that spread anarchy through the world. It's a...

Aaahh...
I see now. Why does God have to take all the spoils >_> (j/k)
But yeah I really should start reading it more. I read some stuff in Corinthians that really made me unhappy because it...

I'm A Christian with some seriously weird beliefs.
God is my master and I would lay down my life for him. I even had a dream once where my brother asked me 'Would you really do this for God'. ...

An unknown substance is placed in water at room temperature and it did not dissolve completely. How would you determine whether that substance has any solubility in water?
You answered your own...
-
Omg I'm so stupid. Oil DOES NOT have a high density, that's why it floats on top of water. It is viscous however.
-
Here's my 2 cents.
If it's going down a ramp, that means there is a component of gravity acting upon it.
The only equation you should remember at this point is F = MA
Force = Mass x...
-
Oil is a viscous liquid with high density. You can only squirt it or smear it. It will never come out in fine droplets unless you use an extremely high pressure canister.
-
1) that decomposes upon heating
2) which is the more reactive metal? Does Fe displace Cu?
3) A more stable salt is created giving off a waste gas - be sure to balance equation
4) A dodgy...

I have a dense material i.e. Lead. I vaporize it into a large volume... Is it still as dense?:confused:
Jesus Christ... *rolleyes*
-
Density is a measure of mass in a given volume. Doesn't matter what mass, if it's packed in a small enough volume, the total density will still increase exponentially.
Btw Capuchin, does density...
-
The divisions of your instruments are your main sources of error. Density is mass x volume (or something like that).
So 2 instruments you will be using are:
Pan Scale (mass)
Ruler or...

m = c x v / 1000
where m = moles
c = concentration
v = volume that you are given.
Re-arrange to find concentration.
-
a. You have 32.9g of Li3N... WHat is this is moles?
Water reacts with Li3N on a 3:1 ratio. Therefore the value you got for part a, multiply by 3 to get the moles for water. Turn this value...
-
Simple laws is the best way to go.
Acid/base reactions
Thermal decompositions
Halogen based reactions
Solubility rules
You must learn all the known laws for your examination board.
-
that is a thermal decompostion if I'm not mistaken.
What do metal chlorates decompose into? Research that and you should be able to write down the correct yeilds ^^

Potassium = K
Chlorine = Cl
Nitrate = NO3
Silver = Au
chlorine has a valency of -1
potassium has a valency of +1
Nitrate has a valency of -2 (please check first!)
Silver I'm not too sure. ...

you are still missing some important enthalpy values, you can't answer the question otherwise.

This is an 'Ask ME' Helpdesk, not a 'please-quote-large-sections-for-me' helpdesk. If the person asking the question wanted quotes he would have done it himself.

Rule number 1:
If you are given the constituents of the reaction - always write out a balanced equation. Thereafter use this equation:
moles = (c x v)/1000
c = concentration of the...

Have you at least found the bond enthalpies or drawn a suitable diagram?
It's impossible to work it out with the above sentence and examiners will not expect you to remember enthalpy...

Dude . If you didn't know then simply don't post. Quoting large sections from a website isn't helping. Don't do it next time.

Graphite is the only non-metal form to conduct electricity. This is because the atoms are aligned in 'planes', therefore delocalized electrons are able to pass through the structure.

Reducing sugars are monosaccarides and disaccarides. If my memory serves me right they discolour benedicts solutions because the above sugars have a Hydroxyl group. This group reacts with the...

I don't think that reaction is feasible to be quite honest. Either I haven't yet reached that level of chemistry or the kinetics of the above reaction simply don't add up.

I don't mean to be anal about this but I've recently stumbled upon this topic over the holidays and I'm thoroughly interested.
What I fail to understand is Order's of Reactions with respect to [X]...

Part of my tectbook that was in the chapter: circular motion. It may be a projectile question though.

If I had my way I'd put a cream there to destroy all of the hair roots.

I love my body but there's one thing I hate and it's pubic hair.
I always seem to get these bumps/spots in the hairy region, sometimes they have erm... pus... in them though I usually pop them and...

Masturbating regularly actually makes it a little softer I've noticed. There used to be times when my became so hard it was physically painful - I could've smashed rocks with it. But I've noticed...

LoL what stupid friends do you have? Being pressured into sex is the most stupid thing I've ever heard of. Whenever I'm with a girl and I ask her if she would like to do it and she's says no, I...

Well since the whole circumference of the wheel is moving at 8ms, then the rim of the wheel moves at 8ms no matter where the tangent is.
So therefore if the clump of dirt is moving in a tangent...

I'm very stupid please explain in more explicit detail.

No I was not given an angle or anything like that, just the above clues I stated

A tractor leaves a muddy field throwing mud into the air with it's rear wheels. The wheels are 1m in radius and the tractor moves off at 8ms-1. What is the maximum height that the mud will reach? ...

I guess this is about light? Well light is refracted. The smaller the space, the greater the refraction - this proves light's small wavelength
Image projectors usually use this mechanism to...

Just what I thought. But I was also wondering if it was something to do with the magnitude and direction of the force applied

Hello there. I've decided this to be a long thread because I will ask many many things and I hope to discuss many things here.
If a coin is placed on a piece of card resting atop of a jar, it is...

I have 2 isotopes of Gallium: 69/31Ga & 71/31 Ga
*numerator = Atomic Number
*denominator = Atomic Mass
The molar mass of a sample of gallium is 69.8 g mol-1
Calculate the percenateg...

Buffer (69.25ml of Na2HPO4, 30.75ml of Citric Acid) pH 6.4 (5ml per test tube)
So an accurate prediction of pH 9 would be 90.00ml of Na2HPO4 and 10.00ml of Citric Acid

This is possibly the worst chemistry subject I've come across.
Can anyone give me a short crash course with examples please?
