Interpretation:
The way by which it is predicted that whether the reaction is endothermic or exothermic if two aqueous solutions are added together is to be stated.
Concept introduction:
An endothermic reaction is a type of
Answer to Problem 1CE
The warm beaker indicates that the reaction is exothermic in nature and the cool beaker indicates that the reaction is endothermic in nature.
Explanation of Solution
After the addition of two aqueous solutions in the beaker, if beaker becomes warm then it is predicted that the reaction between the two liquids is an exothermic reaction.
After the addition of two aqueous solutions in the beaker, if beaker becomes cool then it is predicted that the reaction between the two liquids is an endothermic reaction.
The way by which it is predicted that whether the reaction is endothermic or exothermic if two aqueous solutions are added together has been stated above.

- The thermite reaction combines aluminum powder and iron oxide and ignites the mixture to make aluminum oxide and iron. So much energy is given off that the iron productfrequently is molten. Write a balanced chemical reaction for the thermite process and determine its H(25C).arrow_forwardA _________ is a device used to determine the heat associated with a chemical reaction.arrow_forwardEnthalpy a A 100.-g sample of water is placed in an insulated container and allowed to come to room temperature at 21C. To heat the water sample to 41C, how much heat must you add to it? b Consider the hypothetical reaction,2X(aq)+Y(l)X2Y(aq)being run in an insulated container that contains 100. g of solution. If the temperature of the solution changes from 21C to 31C, how much heat does the chemical reaction produce? How does this answer compare with that in part a? (You can assume that this solution is so dilute that it has the same heat capacity as pure water.) c If you wanted the temperature of 100. g of this solution to increase from 21C to 51C, how much heat would you have to add to it? (Try to answer this question without using a formula.) d If you had added 0.02 mol of X and 0.01 mol of Y to form the solution in part b, how many moles of X and Y would you need to bring about the temperature change described in part c. e Judging on the basis of your answers so far, what is the enthalpy of the reaction 2X(aq) + Y(l) X2Y(aq)?arrow_forward
