Answer:
Bohr thought that electrons orbited the nucleus in quantised orbits. ... In Rutherford's model most of the atom's mass is concentrated into the centre (what we now call the nucleus) and electrons surround the positive mass in something like a cloud. Bohr's most significant contribution was the quantisation of the model.

Explanation:
Answer:
133 mL
Explanation:
M= mol solute/ L solution
mol solute= M *L solution
mol solute = (2.0 M * 0.4 L)
mol solute= 0.8 mol HCl= mol H
We need the same amount of OH moles to neutralize the solution
L solution = mol solute/M
L solution= 0.8 mol Ba(OH)2/ 6M
L solution=0.133 L=133 mL
Answer:
The correct answer is - temperature, state of molecules, and the number of molecules.
Explanation:
The total thermal energy of a system or the total internal energy of a system solely depends on three major aspects of the system's or objects that are the number of molecules or atoms in the system, the temperature of the system, and the state or arrangement of the molecules of the system. More the molecules or atoms present in a system at a particular temperature higher the total thermal energy the system has.
Thus, the correct answer is - temperature, state of molecules, and the number of molecules.
