why are some non-metal oxides basic????

apply law of conservation of momentum...u will get d answer

acc. a=1\v find velocity of particle when its position is x,given that speed is 3m/s @ x =0????

acc. of a particle is increasing linearly with time.acc. is 10 m/s @ t=0 , and 20m/s @t=05.speed is 5m/s @t=0 and position is x=-100m, @ t=0.find @ t time its acc., velocity and position????

acc. of particle is given by a=3t^2+2t+1findvelocity @t time assuming velocity to b 10m/s @t=0,position @t time assuming that d particle is @origin @t time,ave . speed of particle during t=0 t=1????

the near point of a hppermetropic person is 1 m.wat will b d power of d lens required?????assume near point of normal eyes r 25 cm

wat is d formula of valeric acid?????

structure of dimethyl ether,vinyl bromide,1 2 epoxy 5 bromo butane??

wat is optical isomerism???

its very useful gr8 everything in a nutshell....

why do we apply bayer process when simply by heating we can obtain Al???

in blast furnace from where is carbon dioxice is released????

bhaiya ..2 have the balancing's concept u can refer 2 wikipedia-redox reactions

why r nonmetallic oxides neutral????

under what conditions is a reversible reaction possible???

why do not we consider [oh] more than 15 in a Ph scale?

which buk should i refer 2 have a strong grip on electricity chap.?

here first u find 360/30=12 .as d number obtained is even so both in symmetrical n asymmetrical case d answer will b 12-1 =11

how r ketones prepared?(by d oxidation of ....)

bhaiya i m new 2 int. chapter .but still its a try-

(x^4+1)(x^6+1)=x^10+x^4+x^6+1.dx=10x^9+4x^3+6x^5+c

is it right.......
