Why was Niels Bohr’s atomic model superior to all the earlier models?

Answer:

As it demonstrated that how the electron could orbit the nucleus without falling into it.

Explanation:

According to Bohr's model, the electrons revolve around the nucleus at a confined distance in fixed orbits. As long as the electrons move around the orbits, they neither lost nor attain any kind of energy. The jumping of electrons from one orbit to another only takes place when some kind of energy is lost or is supplied.  

Hence, the atom will remain completely stable in the state comprising the smallest orbit, as there is no orbit of lower energy into which the jumping of electrons takes place. Therefore, Bohr's atomic model is superior to all the previous models, as it has demonstrated how the electrons could revolve around the nucleus without falling into it.

What mass of znco3 contains 6.11×1022 o atoms? give your answer correctly to three significant digits?
nordsb [41]

Using Avogadros number, we can get that 1 mole of an atom contain 6.022 x 10^23 atoms. Therefore we can use this conversion factor to get the number of moles:

moles ZnCO3 = 6.11 x 10^22 atoms * (1 mole / 6.022 x 10^23 atoms) = 0.10146 moles

 

The molar mass of ZnCO3 is about 125.39 g/mol, therefore the mass is:

mass ZnCO3 = 0.10146 moles * (125.39 g / mol)

<span>mass ZnCO3 = 12.72 g</span>

Chemical reaction: 4PBr₃(g) → P₄(g) + 6Br₂<span>(g).
</span>Pressure equilibrium constant (Kp) express the relationship between product pressures and reactant pressures. The partial pressures of gases are used to calculate pressure equilibrium constant.
Kp = (p(P₄)  · p(Br₂)⁶) ÷ p(PBr₃)⁴. 
p(P₄) - partial pressure of phosphorus.
p(Br₂) - partial pressure of bromine.
