una pieza de metal de 20g tiene una densidad de 4000kg/m^3 y se sumerge completamente en un recipiente con aceite (densidad: 1500kg/m^3) mediante un hilo ¿cual es la fuerza de flotabilidad ejercida sobre el metal?​

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ

Explain why you think this diagram shows what happened to the carbon in the biodome.

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.
