After a practical chemistry class, a group of students mixed 10 g of zinc (Zn) powder with 25 g of hydrogen sulfide (H2S) in another container. A reaction was observed, and at the end of the experiment, the container weighed 33 g. Based on the observations and knowledge of the ponderal laws of Lavoisier and Proust, answer: (1) What is the product formed in the reaction between zinc and hydrogen sulfide? (2) How does the total mass observed in the container before and after the reaction confirm Lavoisier's Law of Conservation of Mass?Answer sheet:

Imagine that you and your family went camping near a lake for the weekend. Looking at the lake, you remembered that the water there could have passed through many places and been in different forms. Think about the sun heating the lake water, it turning into vapor and rising to the sky, the clouds loaded with vapor, and then the rain falling back into the lake. Describe what happens to the water during this journey, from the lake evaporated by the sun to the rain falling back into the lake, and explain the role of the sun in the water cycle.
