Please answer the below 2 questions **Question:**Which of the following gases effuses most rapidly?- Ammonia- Nitrogen- Oxygen- Hydrogen chloride- Carbon monoxide**Correct Answer:** Ammonia**Explanation:**Effusion is the process by which gas molecules escape through a small hole into a vacuum. According to Graham's law of effusion, the rate of effusion of a gas is inversely proportional to the square root of its molar mass. Therefore, gases with lower molar masses effuse more rapidly. Among the options given, ammonia (NH₃) has the lowest molar mass, making it the gas that effuses most rapidly. **Question:**Which of these chemical equations does not describe a redox reaction? Show the oxidation states of all elements of the answer you chose.**Options:**A) \( 2\text{KBr}(aq) + \text{Cl}_2(g) \rightarrow 2\text{KCl}(aq) + \text{Br}_2(l) \)B) \( 2\text{Na}(s) + 2\text{H}_2\text{O}(l) \rightarrow 2\text{NaOH}(aq) + \text{H}_2(g) \)C) \( 2\text{LiOH}(aq) + \text{H}_2\text{SO}_4(aq) \rightarrow \text{Li}_2\text{SO}_4(aq) + 2\text{H}_2\text{O}(l) \)D) \( 3\text{NO}_2(g) + \text{H}_2\text{O}(l) \rightarrow 2\text{HNO}_3(aq) + \text{NO}(g) \)E) \( 2\text{KNO}_3(s) \rightarrow 2\text{KNO}_2(s) + \text{O}_2(g) \)

Below are 3 real life situations. Pick two (2) them and explain ALL the science involved in the scenario. This means describe things like what is happening to the gas/liquid/solid molecules or atoms, which principles or laws are at work, why what is happening is happening, and how you know. At sea level, a pot of water will boil at 100 °C. Suppose you wanted to boil the same amount of water high in the Rocky Mountains. What do you expect the temperature will need to be (generally speaking)? Why? A can of soda sits in a sunny spot on the window sill for several hours. It is then opened at the same time as a cold can of soda from the refrigerator. What happens and why? Weather balloons do not float out into space.
