The main concept is that we do not know the number of bonds so we dont say in those terms.However we say in energy terms like in exo,energy released during bond formation is more than energy absorbed during bond breaking.
adding..those r van der waal forces
its cant be ....becuz matallic bonding only in metals ....there are free electons between its layers....each carbon is covalently bonded to only three others so one electron is not invovled in bonding...but it has no sea of electons...
heheYup
Thanks for the correction, mate
Actually this is wrong to call it metallic bonding. This is clearly mentioned everywhere that there is covalent bonding, however the carbon atoms are not completely bonded. It does not even have a metallic like no positive ions.
Yeah you have a point, but there must be something that allows free electrons to be present
I call it incomplete covalent bonding.
It's in grams so we find mass of the sulphuric acid.
Thanks a bunch.
Yeah!! But in the maths thread
changing gravitational feild wont effect the mass.........and hence the weight of all object would be changed equally...and hence the rod would be in equilibrium......
to calculate the resistance in parralel circuits you need to apply the formula 1/R(total resistance= 1/r +1/r .....so the resistance is 2
the answer is c simce it says tht i cm= 5ms... so in one complete wave there were 4 cm's....therefore 4*5 = 20 ms
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
