Question

please explain 1 . question​ meaning. 2) step by step solution by using solution from book but instead add some more details for eg. tell me why eq. ofmetal = eq of chloride and what is this a + 35.5 n = 100

Answer 1

hope it help u...if did then mark as brainliest...

Answer 2

step 1 :- molecular weight = 2× vapour density
= 50 × 2 = 100 g/mol

step 2:- metal chloride ,
let metal n electrons loss to form stable ions .eg M → M+n + ne

also we know,
chlorine accept only one electrons so,
CL → Cl- -e

hence ,
formula, = MCln

so, formula, mass = M + n× 35.5
so, M + n× 35.5 = 100 -----(1)

and , n×35.5/100 × 100 = 71
n = 2

so,
M + 71 = 100
M = 29 g/mol
