Make a sketch of a concentration cell employing two Zn/2+ half-cells. The concentration of 2+ in one of the half-cells is 2.0M and the concentration in the other half-cell is 1.0x10−3M. Label the anode and the cathode and indicate the halfreaction occurring at each electrode. Also indicate the di-rection of electron flow.

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

What best discribes the relationship between wavelength and frequency in a electromagnetic wave

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
