In the formula of crystalline CuSO4 I.E.:-CuSO4.5H2O, wHAT DOES THE 5H20 STANDS FOR???

need a help for investigatory project i want a practical topic for this project. can anybody help me out? pls reply fast!!!

i want a topic for investigatory project of biology...

A mark on the rim of a rotating circular wheel of 0.50m radius is moving with a speed 10m/s. Find its angular speed.

density=mass/volume =59.82/65 =0.92

i think because of the displacement.there is displacement and a force is applied for great speed. I f i m wrong pls interuppt me.

i think more than painting there will be more systems of photograph and printouts from the printer. there won't be much demand for painting. infact new yongsters r very lazy so they can't even think of making a printer. there will very few people left, wh...

k thanks

when the sun sets or while rotating earth is not facing the sun, there is darkness everwhere which is referred to as night.. i thimk so!!!

i think your partner is right as density is directly proportional yo yhe mass,which is given by no. of protons.more the protons more is the nuclear effective charge, which attracts the electorns towards the nucleus and make a denser atom.

a) the ans. is 4/20C5 because there are 4 types of balls and 5 is the magnitude of a specific colour. b)5C3 gives value of 3 balls of 1 colour; 5C2= value of 2 balls of another colour; 4P2= probality of 2 colours from 4 colours ; 20C5=combination of total...

Na=23g l=7g therefore:- 1mol=23+7g=30g 6.78=(x)g x=30*6.78 x=203.4g

i think B is correct

monday=1 mile tuesday=2*1=2miles wed=2*2=4 miles thursday=4*2=8miles friday=8*2=16miles total miles=1+2+4+8+16 =31 miles hope u might understood it!!!
