E=hc/λ =6.626×10^-34×3 ×10^8 / 3×10^7 × 10^-9 = 6.626×10 ^-24J.
Answer:
C. He shot tiny alpha particles through a piece of gold foil.
Explanation:
In the year 1911, Ernest Rutherford performed the gold foil experiment which gave a deeper perspective to the structure of an atom.
He simply collided a thin gold foil with an alpha particle which he generated from a radioactive source. He discovered that most of the alpha particles passed through the thin gold foil but a few were deflected back. His discovery led to the proposition of the nuclear model of the atom.
It could be
C + 2Cl2 ➡️ CCl4
I decided this because I believe this is the only way you could make this a balanced equation. To be a balanced equation Both sides of the equation has the same number of atoms for each element. Carbon has 1 atom and chlorine has 4.
