Fill in the blank. (Copper has a charge of 2+)
Cu+ AgNO3 → Ag +

The equation can be written as :-

=》Cu + AgNO3 -> Ag + Cu(NO3)2

so, the term suitable for the blank is :-

" Cu (NO3) 2 "

( note the equation isn't balnced )

balanced one is :

Cu + 2 AgNO3 -> 2 Ag + Cu(NO3)2

Cu(NO3)2

Explanation:

Cu+AgNO3--->Ag+Cu(NO3)2

the answer would be c

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
