Answer:
Cu, Zn(NO3)2
Explanation:
Zn is more reactive than Cu, so Cu will be displaced (replaced) in the reaction above.

A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute.
Answer:
variable: not consistent or having a fixed pattern; liable to change.
Explanation:
Answer:
c) non polar Covalent
Explanation:
this is a molecule formed by atoms of the same element . they both have similar electronegativities and thus cancel out . This makes it a perfect Covalent molecule . The fact that it's a symmetrical molecule makes it non polar. a symmetrical molecule is a molecule formed by the overlap of orbitals of two atoms of the same element ( that is to say , there's no dipole )
