elate Active Learning Question 2 from Chapter 2 to the concepts of chemical stoichiometry.
Expert Solution & Answer
Interpretation Introduction
Interpretation:The Active Learning Question 2 from Chapter 2, that is the number of dimes needed to buy as much candy as possible,is to be related with the concepts of chemical stoichiometry.
Concept Introduction:Stoichiometry helps in determining the relationship between the number of moles of the reactants and products that are involved in a reaction. For proper calculations, the reaction must be balanced.The reactant that determines the concentration of the product formed in a chemical reaction is known as limiting reagent. The other reactants left in the reaction mixture are termed as reactants in excess.
Answer to Problem 1ALQ
The question’s concept is similar to chemical stoichiometry. The stoichiometric coefficient of the reactants helps to predict the product of the reaction.
Explanation of Solution
The total mass of penniesis given to be 636.3g .
The weight of each penny is given to be 3.03g .
To buy 10.23g of candy,
3 pennies and 2 dimes are required. It can be represented by a chemical equation as shown below.
3pennies+2dimes→10.23 gcandies
The above equation indicates that 3 pennies require 2 dimes to buygiven mass of candies.
Hence, from the above chemical equation, one can calculate the number of candies from the given amounts of the reactants.
This question’s concept is like chemical stoichiometry. The stoichiometric coefficient of the reactants helps to predict the product of the reaction. The limiting reagent (the species present inlesser amount) governs the formation of the product. The limiting reagent in the above reaction will be dimes because it is present inlesseramount. Therefore, the question’s concept is similar to chemical stoichiometry.
Conclusion
The question’s concept is likechemical stoichiometry. The stoichiometric coefficient of the reactants helps to predict the product of the reaction.
