Answer 1

To determine changes in the moles of gas during a reaction, analyze the stoichiometry of the chemical equation and mole-to-mole conversions. The moles of gas will increase or decrease based on whether there are more or fewer gaseous products than reactants, respectively.

Step-by-step explanation:

To determine if the moles of gas in a container increase, decrease, or remain constant during a chemical reaction, we must examine the coefficients of gaseous reactants and products in the chemical equation.

The change in moles of gas can be understood through the concept of stoichiometry, which involves mole-to-mole conversions between reactants and products.

For instance, if a chemical reaction has more moles of gaseous products than reactants, the moles of gas will increase as the reaction goes to completion. Conversely, if there are fewer moles of gaseous products than reactants, the moles of gas will decrease.

When analyzing reactions in closed systems,

the Le Chatelier's principle may be applied to predict the shift in the reaction when changes such as pressure or volume occur.

If the volume decreases, for example, the reaction will shift in the direction that reduces the number of moles of gas, to minimize the change imposed on the system.

Answer 2

The assessment of whether the moles of gas in the container increase, decrease, or remain constant during a chemical reaction involves a visual examination of the provided images. After careful scrutiny, the images can be appropriately categorized based on the observed changes in the number of moles of gas throughout the progression of the reaction.

Step-by-step explanation:

To determine the changes in moles of gas, each image must be analyzed for the reactants and products involved in the chemical reaction. If the number of gas molecules increases from the reactants to the products, it signifies an "Increase Moles of Gas" scenario. Conversely, a decrease in the number of gas molecules indicates a "Decrease Moles of Gas," and if the count remains the same, it falls under "Constant Moles of Gas." This categorization aligns with the fundamental principles of stoichiometry and the balanced chemical equation.

The qualitative analysis of the images provides insights into the stoichiometry of the chemical reactions, allowing for a determination of the net change in moles of gas. Balancing the chemical equation is crucial, as it ensures an accurate representation of the stoichiometric coefficients, reflecting the ratio of reactants to products. This understanding is fundamental to categorizing the images correctly based on the observed changes in moles of gas.

In summary, the visual inspection and categorization of images into "Increase Moles of Gas," "Decrease Moles of Gas," or "Constant Moles of Gas" require a careful consideration of the stoichiometry inherent in the chemical reactions. This process aids in translating visual information into a qualitative assessment of the changes in moles of gas, contributing to a deeper understanding of the reaction dynamics.
