integral problem but you're probably all starting to get bored of them ;-) I'll still have a go, you know me

e^i*pi = -(phi)^0

Yes i could tell, by using KPa as pressure and 8.314 as the gas constant, your welcome anytime.

Look here Md: http://www.montessorimom.com/antcity.html

Calculate the volume occupied by 0.0950 mol of calcium phosphate at 25oC and 101.3 kPa, given its density at this pressure and temperature is 3.14 g/mL. Do as dave said for the ml/per gram, then use: V = P / nRT Where V = Volume (L or dm-3) P = Pressure use 1 atm, as your 101.3Kpa = 1 atm n = number of moles which you calculated. R = gas constant of 0.0821 J.K.Mol-1 and T = temperature, that 25 oc = 298.3 K<<<use the K.

You wouldn't think I was doing a maths degree at university really, would you Yes i would students all have there blonde moments, as I forgot my chemistry calculation the other day.

R, is 8.314 J/K.mol. grrrr and 101.3 kPa grrrr. atm and 0.0821 J/K.mol-1, btw how old is your teacher. V = P / nRT V= volume n= number of moles R = Gas constant (0.0821) or in your case 8.314 J.K.mol-1 T= Tempertaure (K) Oh and as for Ideal gas, N at really low K has a volume of 22.362 L.

Tell him to look up kinematics, and free-fall.

If a ball id throw to its max height, the ball will have a downward accelartion of g (gravity) 9.81 ms-2 So if the bullet would fired at 60ms-1 Then reached its max height it would traveel down at g. So the inital velocity would be different from the free-fall (g).

Ok IGNORE, why did you bother joining this group, we really dont need morons here, this is for science DISCUSSION, not for little children to use offensive word(s), so from now on i will not have to listen to your rubbish.

Initial and Final Velocity are different saint, and bunty what an idiot keep it up and you will be on my ignore list.

v^2 = u^2 + 2as Sq root of U^2 + 2as = v Where u =inital velocity, a = acceleration and s = displacement.

The state of d-block elements and there instability.

Sayonara³ yes well said have a reputation thingy for that

due to the weird things the "d" orbital can do Are you talking about superintentions?

CH = cerebral hyperactivity, similar to the contusions seen in the prefrontal cortex on an alcoholics brain. Whereas the Hippocampus is near to the amygdala, and the pituitary galnd. Hoped that helped you.

Calculate the mass of iron(III) sulfate required to prepare 150.0 mL of a 0.1235 M solution. Number of moles = Volume.Molarity Volume in L or dm-3 Number of moles = (150/1000) x 0.1235M = 0.0185(25) 3.S.F. Mass = Molecular weight.Number of moles Mass in grams Molecular weight = Fe(55.845g) + S (32.066) + 04 (63.998) = 151.909g Thus: Mass = 151.909 x 0.0185 = 2.810 g. Wolfson

Marijuana has demonstrated neurotoxicity to cells in the hippocampus, resulting in memory loss. And may also cause induced CH in the pons region.

Why ty YT

Light year is distance light travels in a year: Light travels at approx 3.0e8 m per second So in a year: Light travels = 3.0e8 * 60 *60 * 24 * 365 = 9.4608e15 Light year(s) from earth = 4.07e16 / 9.4608e15 = 4.30(1961779). Yes that correct

albertlee, people will answer your questions. 1. In due time, dont be hasty 2. If you wish to ask another question start a NEW thread, do not repeat yourself on the same thread. Wolfson
