what has a complete ionic equation of
mg(s) + zn2+ + 2no3 → mg2+ + 2no3- + zn(s)?
o a. mg(s) + 2zn(no3)(aq) → 2mgno3(aq) + zn(s)
o b. mg(no3)2 + zn(s) → zn2+ + 2no3 + mg(s)
o c. mg(s) + zn2+ → mg2+ + zn(s)
o d. mg(s) + zn(no3)2(aq) + mg(no3)2(aq) + zn(s)

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
