In nuclear reactions, there are can be two kinds: nuclear fission and nuclear fusion. From the word itself, fusion is combination while fission is breaking. Nuclear reactions are different from chemical reactions. Whereas chemical reactions from compounds by exchanging elements, nuclear reactions add or eliminate subparticles, like protons, neutrons and electrons.
So, when carbon is split up, their protons should add up to 6, which is its atomic number. From the choices, the only obvious answer is two lithium atoms. To investigate further, lithium has an atomic number of 3. So, two lithium atoms would equal to 6.
Therefore, the answer is <span>two lithium atoms.</span>
Explanation:
In an alpha emission, an alpha particle is ejected from a large nucleus. An alpha particle is simply a helium nucleus (atomic number is 2 and mass number is 4) so that means that the atomic number of the emitting nucleus decreases by 2 and its mass number decreases by 4.
In general terms, exothermic reactions release energy, so the energy goes from the system to the surroundings.
Answer:
Population of duck and frog will change with the change
Explanation:
The complete question is
Scientists are studying animals in a large lake area. In this lake area, both owls and raccoons eat ducks, and ducks eat frogs. The data shows that recently the size of the raccoon population decreased. How will the decrease in the raccoon population affect the other populations? Be sure to explain whether the owl population, the duck population, and the frog population will change, and why.
- Owl population will change
-
Duck population will change
-
Frog population will change
Solution
Raccoon eat duck and duck eat frog. Now if the population of Raccoon decreases then the number of predators of duck will decrease thereby increasing the population of duck.
The higher will be the number of ducks, the more frogs they will consume thereby decreasing the population of frogs
Hence both the population of duck and frog will change with the change
