Hello there.
Thomson's atomic model is best described by which of the following statements?
A nucleus with electrons moving around it like planets.
<span>The balanced reaction that describes the reaction between hydrogen and nitrogen to produce ammonia is expressed 3H2 + N2 = 2NH3. The yield of the reaction is equal to the actual amount of product divided to the theoretical amount of product multiplied by 100 percent. 26.3 grams of H2 theoretically produces149 grams. The yield is 79 divided by 149 equal to 53.02 percent. </span>
Answer:
I think its D
Explanation:
It cant be B or C bc the solute particles arent changing. And its not A because the concentration isnt constant
Answer:The purple color is due to a mixture of the pink aqua complex and blue chloro complex and is not due to a new species.
Explanation:
The pink aqua complex of cobalt can be in equilibrium with blue chloro complex of cobalt giving rise to a purple colour. This equilibrium is governed by Le Chaterliers principle. A change in chloride or water concentration could shift the equilibrium towards any of the species causing its colour to become the dominant colour of the solution.
