Answer:
The answer is A
Explanation:
Because . . .
- A is correct because scientist make their statements by using their observations and tools to measure.
- B is incorrect people's opinions are not facts! Plus, opinions can be wrong.
- C is incorrect because that book can be outdated and not every answer is in a book.
- D is absolutely incorrect because guessing a "right" answer can be wrong. For example, if you were a scientist and you guessed a treatment for coronavirus, you will defiantly get fired because you don't have evidence or logic to back up your answer. In addition, if people used ur "treatment" the one you have guessed as the "right" answer, you can put people's lives in danger and they can possibly die. You will defiantly be responsible for it and be put into jail.
Warm air is less dense than cool air, which is why it rises. Let me know if you have any follow up questions on this!
The correct choice is "cannot be determined" because of weight and height differences
Question:
<em>For an exothermic reaction at equilibrium, how will increasing the temperature affect Keq?</em>
Answer:
<em>The reaction will proceed towards the liquid phase. Heat is on the reactant side of the equation. Lowering temperature will shift equilibrium left, creating more liquid water. A reaction that is exothermic releases heat, while an endothermic reaction absorbs heat.</em>
<em>If you increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again. It will do that by favouring the reaction which absorbs heat. In the equilibrium, that will be the back reaction because the forward reaction is exothermic.</em>
