The accepted model of the atom was changed. JJ Thomson discovered the electrons and performed experiment using the cathode ray tube. The model before his did not have electrons so the model was changed. Hope this helps
The
balanced chemical reaction is:<span>
N2 + 3H2 = 2NH3
<span>We are given the amount of the product to be
produced. This will be the starting point of our calculations.
17 mol NH3 ( 1 mol N2 / 2 mol NH3 ) = 8.5 mol N2
Therefore, the required N2 to produce the given amount of ammonia is 8.5 mol.</span></span>
Answer:
Radio waves are a type of electromagnetic radiation and they use it for communication for things like phones,computers, and just mobile devices.
An object in motion, will remain at a constant velocity unless an unbalanced force comes upon it and that is a proven fact.
Lower as KCl has ionic bonding which is less stable than CaCl2s covalent bond which requires less energy.
