Iron forms two chlorides.One gram of the first chloride produces 2.26g of silver chloride and one gram of the second chloride produces 2.65g of silver chloride.Prove that these data illustrate the law of multiple proportions

1. In an equilibrium, A + B ---> C + D; "A" & "B" are mixed in a vessel at temperature "T". The initial concentration of "A" was twice the initial concentration of "B", & after the equilibrium has reached, concentration of "C" was twice the equilibrium co...

13. A ball is thrown vertically upwards and it returns to the thrower after 6 sec ( g=9.8 m/s2) Find. (i) The velocity with which it was thrown up. (ii) The maximum height it reaches (iii) Its position after 4 sec.

A particle is dropped from height 100m and

The radius of thd base of a cylindrical oil can is 4m.find its height if it can contain 1408kl of oil.

If the 3rd and 9th term of an ao are 7 and -8 respectively, which term of this ap is zero

I too wonder what it means

p.d.=100000V therefore, workdone , W=q×p.d. W=1.6×10^-19 × 100000 =1.6×10^-14 Joules since work done = force × displacement F×s=1.6×10^-14 m×a×s=1.6×10^-14 9.1×10^-31×a×s=1.6×10^-14 a×s=(1.6×10^-14)÷(9.1×10^-31) a×s=1.75×10^17 v^2/2=1.75×10^17 v=5.09×10^8...
