(Originais Teachy 2023) - Question Medium of Chemistry

Suppose you are a scientist working in a laboratory and have received two unknown samples to analyze: sample A and sample B. After conducting experiments and observations, you discover that sample A is composed of molecules of a single type of atom, while sample B is composed of molecules of two different types of atoms, bonded together. a) Identify whether each sample is a simple or compound substance and justify your answer. b) Explain what allotropes are and give an example of a substance that exhibits allotropy. c) Mention a reliable source of information about chemical substances and discuss the importance of seeking information from reliable sources.

In a Chemistry class, the teacher presents to the students an experiment using a mixture of water, sand, and oil in a container. After stirring this mixture and waiting for it to settle, it is possible to observe the separation of visible components. Based on this context, what is the number of phases and their respective components that the students can observe in the mixture after its separation?

Question 4:

Easy

In the field of chemistry, the kinetics of elementary reactions plays a crucial role in understanding how chemical reactions occur. Collision theory, which is a part of this field, provides insight into how the rate of reaction depends on the frequency of collisions between reactant molecules. Considering this, explain how the rate of an elementary reaction might be affected if the frequency of effective collisions between reactant molecules changes. Also, discuss how this change would impact the overall reaction.
