This of the following is an electrovalent linkage: (1) CH 4 (2) MgCl 2 (3) SiCl 4 (4) BF 3 Ans: MgCl
process of metullergy.
The determination of k is not a strait forward exercise. Model it from first principles using Bernoulli's equation would produce a square root relationship and would probably have
