Answer 1

Answer:

+3

Explanation:

X+4(-1)= -1

X = -1+4

X= 3

Answer 2

Answer:

Boron is in +3 oxidation state.

Explanation:

Here, in [BF4]^-1

we know that Fluorine being the most electronegative element, its oxidation number will be always -1 , there for,

let x be the oxidation number of Boron and oxidation number of Fluorine is -1

thus,

x+(-1x4)=-1

x-4=-1

x=+3
