The hypothesis of Thomson's atomic model was that an atom is posively charged sphere and in which negatively charged electron are embedded in it but later it was found to be not true by niels Bohr.
The above hypothesis of Thomson's atomic model was false because according to niels Bohr 'The mass of any atoms is localize at the center of an atom which is positively charged while negatively charged electrons revolved around the positive charged'.
The J.J Thomson give the world Thomson model of the atom in 1904 . Thomson model is also known as the plum pudding model .

Answer:
239.7 g
Explanation:
Step 1: Write the balanced equation
2 LiBr + I₂ → 2 LiI + Br₂
Step 2: Convert the molecules of iodine to moles
We have 9.033 × 10²³ particles (molecules) of iodine. In order to convert molecules to moles, we will use the <em>Avogadro's number</em>: there are 6.022 × 10²³ molecules of iodine in 1 mole of iodine.
Step 3: Calculate the moles of bromine produced
The <em>molar ratio of I₂ to Br₂</em> is 1:1. Then, the moles of bromine produced are 1.500 moles.
Step 4: Calculate the mass of bromine
The <em>molar mass of bromine</em> is 159.81 g/mol. The mass corresponding to 1.500 moles is:
Answer:
According to Avogadro's law, the volume of one mole of any gas at Standard Temperature and Pressure (STP = 273 K and 1 atm) is 22.4 L. Two important Gas Laws are required in order to convert the experimentally determined volume of hydrogen gas to that at STP. 1.
