A student practices the reaction above in a laboratory to generate sliver metal. He mixes 3.20 g of metal with excess AgCl, and his actual yield is 27.7 g of Ag metal. Calculate the percent yield of this reaction. The equation is in the image.

Can someone help with this problem?

a) the particles of the chair are strongly held together.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

the answer is c.the valence of the atoms combine .
