After 1911, most scientists accepted the theory that the nucleus of an atom was very dense and very small and had a positive charge. what led scientist to accept this theory?

a) dalton’s theory of the atom was over 100 years old

b) scientists before 1911 used the scientific method of inquiry improperly

c) a new model proved that the quantum theory of the atom was inaccurate

d) rutherford did an experiment firing alpha particles at a thin piece of gold foil

I believe it is D

Explanation:

since Rutherford's explanation, when he made it in 1911, was that scattering was caused by a hard, dense court to centre of the Adam, which is the nucleus and he used Alpha particles to observe the scattered backwards from a gold foil

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.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
