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...

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.

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.

Erm, maybe an oxide?

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?
