-less than 100 years ago he discovered a subatomic particle that does not have a charge
-used a cathode ray tube to detect negative charges
-concluded that the atom is mostly empty space with a dense nucleus that contains most of the atom's mass
-supported the ideas of democritus using the scientific method

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

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).

i think that the answer is c
