Agalvanic (voltaic) cell has the generic metals x and y as electrodes. x is more reactive than y , that is, x more readily reacts to form a cation than y does. classify the descriptions by whether they apply to the x or y electrode.
(c) electrons in the wire flow toward
(d) electrons in the wire flow away
(e) cations from salt bridge flow toward
when lithium metal reacts with nitric acid it forms lithium nitrate and hydrogen gas. the balanced chemical reaction:
in replacement reaction the element reacts with compound by taking the position of the another element in the compound.
here also in the given reaction lithium replaces hydrogen atom from the nitric acid and forms lithium nitrate.

in the majority of the power plants, there is a need to spin a turbine in order to produce electricity. natural gas, coal, nuclear energy, and oil, utilize their fuel to convert water into steam and use that steam to turn the turbine. however, nuclear plants are distinct as they do not burn anything to produce steam, in spite, they dissociate the atoms of uranium in the process known as fission.
as an outcome, unlike other sources of energy, the nuclear power plants do not discharge pollutants like sulfur oxides and nitrogen into the air. the nuclear reactors are created to maintain an ongoing chain of the fission reaction. they are occupied with a uniquely created, solid uranium fuel and surrounded by water that in the procedure.
with the start of the reactor, the atoms of uranium will split, discharging heat and neutrons. these neutrons will stimulate other atoms of uranium and makes them to dissociate and to carry the procedure, producing more heat and more neutrons. this heat is used to produce the steam, which will rotate a turbine that powers a generator to produce electricity.
