Nuclear energy is called the energy obtained by the transformation of atomic nuclei, so small and heavy clusters of particles inside the atom. Nuclear energy can be produced in two ways, by cleavage or synthesis of nuclei. Heavy nuclei of radioactive elements such as uranium or plutonium, can be split into two nuclei. By splitting are released from the nucleus of neutrons that collide with other nuclei causing them to split and subsequent emission of neutrons. This is called a chain reaction. The condition calls self-sustaining nuclear reaction is slowing down neutrons. For this purpose, a special substance, called moderator. The neutrons collide with the molecules of the moderator precipitate heating speed while the moderator. The resulting heat heats the water so that a couple who drives a turbine generating electricity. Another way of producing nuclear energy is nuclear fusion, in which nuclei combine to light elements. So far, fusion, however, failed to carry out so that it can be applied to the economy as a source of energy.
Answer:
Lithium, Potassium and Calcium
Explanation:
Because they are all in group one of the periodic table
ANSWER
EXPLANATION
Given that;
The two reactants are KBr and CaO
Double replacement reaction is a type of chemical reaction that occur when two reactants exchange cations and anions to yield new products.
Therefore, the resulting products of the given data are K2O + CaBr2
The correct answer is option B
