The anode is charged positively. Oxidation happens on the anode.
For example,
(anode +) Zn - 2e⁻ = Zn²⁺
All rivers erode the land over which they pass rendering a more gradual radiant to surrounding areas overtime.
Air is mainly composed of N2 (78%), O2 (21%) and other trace gases. Now, the total pressure of air is the sum of the partial pressures of the constituent gases. The partial pressure of each gas, for example say O2, can be expressed as:
p(O2) = mole fraction of O2 * P(total, air) ----(1)
Thus, the partial pressure is directly proportional to the total pressure. If we consider a sealed container then, as the temperature of air increases so will its pressure. Based on equation (1) an increase in the pressure of air should also increase the partial pressure of oxygen.
Answer:
carbon atom is used to determine the amt of particles in a mole
