when radioactive uranium decays to produce thorium, it also emits a particle. as seen in the balanced nuclear equation, this particle can best be described as
a) a helium atom.
b) an alpha particle or a helium atom.
c) a beta particle or a hydrogen nucleus.
d) an alpha particle or a helium nucleus.

explanation: no but i do not usually comment

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

the answer is barium and copper bromide
