what is the reactant(s) in the chemical equation below?
cu(s) + 2agno3(aq) → 2ag(s) + cu(no3)2(aq)

a. 2ag(s) + cu(no3)2(aq)
b. 2ag(s)
c. cu(s) + 2agno3(aq)
d. cu(s)

hmmmm let me think about that

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

by using relative and radiometric dating methods hope this
