Answer:

Convert into an atom of lithium-8.

Explanation:

Your nucleus has three protons and four neutrons, so you have an atom of lithium-7.

If you add a neutron, you are creating an isotope of lithium with one more unit of mass.

That is, you are forming an atom of lithium-8.

What mass in grams of Ag is produced from reaction of 31.75 g of Cu

wariber [46]

<span>Copper metal (Cu) reacts with silver nitrate (AgNO3) in aqueous solution to form Ag and Cu(NO3)2. An excess of AgNO3 is present. The balanced chemical equation is shown below.

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

The molar mass of Cu is 63.5 g/mol. The molar mass of Ag is 107.9 g/mol. What mass, in grams, of Ag is produced from reaction of 31.75 g of Cu?
