How many grams of copper would you need to add if you wanted to produce 8.000 grams of silver? the atomic mass of copper is 63.55 g/mol, and the atomic mass of silver is 107.87 g/mol.

Moles of solid copper used in reaction, using molar mass: 1 gram Cu @ 63.55 g/mol = 0.0157 moles Cu (f) Moles of solid silver produced in reaction , using molar mass: 3.395g Ag @ 107.87 g/mol = 0.317 moles of Ag Write the net ionic equation for the reaction between, using your mole values: 0.0157 Cu (s) & 0.317 Ag+ --> 0.0157 Cu+2 & 0.317 Ag (s) Convert to whole number ratio, by dividing by the smaller : 0.0157 moles Cu / 0.057 = 1 mole Cu 0.317 moles Ag+ / 0.157 = 2 moles Ag and rewrite the equation using the whole number ratio: 1 Cu (s) & 2 Ag+ --> 1 Cu+2 & 2 Ag (s)

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
