In one example of nuclear fusion deuterium, with one proton and one neutron, andtritium, with one proton and two neutrons, combine to form helium, with two protonsand two neutrons. We can conclude that during this process A. alpha particles are absorbed.
B. the charge of deuterium reverses.
C. a new atom of tritium is formed.
D. one neutron must be released.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
