Answer: CaF2
Explanation:
Calcium is a metal and has 2+ cation charge. While F us in group 7 with an oxidation of -1.
So. Ca²+ F- do the criss cross rule where the charge of the cation will be the subscript of the anion and vice versa. So the result is CaF2
Mirror formula
1/f = (1/p) + (1/q) [ f= focal length , p= object distance , q = image distance ]
as given convex mirror so
distance of object =p= 6cm
focal length = -8cm
to find q=?
1/q =( 1/f) - (1/ p)
1/q = (1/ 8) -(1/6)
1/q =-1/24
q=-24 ( negative sign shows image is virtual and behind the mirror)
In a parallel circuit nothing happens. All the other lights stay on but if it was a series circuit ALL the lights would turn off at one time.
If there is an ABCD question I can answer that but I wasn't sure so I just said this
Hope it is helpful :)
