If 6.51 g of copper is reacted with 28.4 g of silver nitrate, the products will be copper (ii) nitrate and silver metal. what is the theoretical mass of silver that will be produced?

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

Now, since the theoretical yield of silver is required, we first must identify the limiting reactant by comparing the available moles of copper and the moles of copper that are consumed by the 28.4 g of silver nitrate as shown below:

Hence, since there are more available moles of copper than consumed, we understand copper as the excess reactant and silver nitrate as the limiting one, therefore, the theoretical yield of silver turns out:

Best regards.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
