Answer:
the answer is Fe2O3
Explanation:
The thermite reaction is described by the equation below: A welder has ... How much of this reactant should he order to make sure he runs out of both reactants at the same time? Round to the nearest hundredth and do not round any of your work until the very end. He should order Fe2O3 g of the limiting reactant.
Answer : The correct option is (A) Hydrogen region of the molecule.
Explanation :
As we know that the water molecule has two hydrogen atom and one oxygen atom. The hydrogen atom has partial positive charge and oxygen has partial negative charge.
In the charged plate, the negative attracts positive and positive attracts negative. So, the hydrogen atom attracted to the negative plate and the oxygen atom attracted to the positive plate.
When water molecule placed between oppositely charged metal plates which is positively charged, then the hydrogen atom which is positively charged attracted towards the negative plate.
Answer:
Rutherford's theory laid the foundation upon which Bohr's model is founded. Rutherford established the fact that at the center of the atom, there is a nucleus whose radius is smaller than the radius of the atom. This nucleus is positively charged and most of the mass of the atom is concentrated there. Electrons move round this nucleus in orbits.
The experimental evidences of the Bohr's model shows that Rutherford's model was fundamentally correct. However, Bohr's model introduced the idea of quantization of the energy of electrons in an atom. The model went further to explain the spectra lines of the hydrogen atom.
