The hypothesis of Thomson's atomic model that was later found to be not true by Niels Bohr is that the atom was made up of uniform spheres of positively charged matter in which electrons are embedded.

That the atom was made up of uniform spheres of positively charged matter in which electrons are embedded.

In about 1900 Thomson proposed the atomic model that atom was made up of uniform spheres of positively charged matter in which electrons are embedded. The atom was a sphere of positive charge surrounded by negative charges lumped up together like in a plum pudding.

In 1903  Niels Bohr and Rutherford proposed a model which explained the scattering of electrons by gold foil that the atoms was made up of empty space and a positively charged nucleus surrounded by an electron in what they called a planetary model.

The reason why the Thomson atomic model was found not to be true by Niels Bohr is that it could not explain the scattering of atoms by the gold foil. In the gold foil experiment, most of the electrons fired at the gold foil passed through the atom but some were deflected showing that the atom was made up mostly of empty space and concentrated at the center.

So, hypothesis of Thomson's atomic model was later found to be not true by Niels Bohr is that the atom was made up of uniform spheres of positively charged matter in which electrons are embedded.

When 500.0 g of water is decomposed by electrolysis and the yield of hydrogen is only 75.3%, how much hydrogen chloride can be m
Evgen [1.6K]

The amount of hydrogen chloride that can be made is 1064 g

Why?

The two reactions are:

2H₂O → 2H₂ + O₂ 75.3 % yield

H₂ + Cl₂ → 2HCl 69.8% yield

We have to apply a big conversion factor to go from grams of water (The limiting reactant), to grams of HCl, the final product. We have to be very careful with the coefficients and percentage yields!

500.0gH_2O*\frac{1moleH_2O}{18.01 gH_2O}*\frac{2 moles H_2}{2 moles H_2O}*\frac{2.015g H_2}{1 mole H_2}*\frac{75.3 actual g}{100 theoretical g}=42.12 g H_2

42.12H_2*\frac{1 mole H_2}{2.015gH_2}*\frac{2 moles HCl}{1 mole H_2}*\frac{36.46g}{1 mole HCl}*\frac{69.8 actualg}{100 theoreticalg} =1064gHCl

Have a nice day!

Which reaction results in only a physical change?
Advocard [28]
D will because water just turns from liquid to a gas by adding heat. That is a physical change. The other equations are chemical changes.
