The balanced chemical equation for the reaction of copper (cu) and silver nitrate (agno3) is shown below. cu + 2agno3 es002-1.jpg 2ag + cu(no3)2 how many moles of agno3 must react to form 0.854 mol ag?

Moles of that must be reacted are 0.854 moles.

Explanation:

For the given chemical reaction, the equation follows:

By Stoichiometry of the reaction:

2 moles of silver are produced when 2 moles of silver nitrate is reacted.

So, 0.854 moles of silver is formed when = of silver nitrate is reacted.

Thus, moles of that must be reacted are 0.854 moles.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
