Answer all three of the questions in the picture Consider the reaction of copper(I) oxide with carbon, which is used in a step during the extractionof copper metal from chalcocite:Cu₂O (s) + C (s) → 2Cu (s) + CO (g)(a) Without doing any calculation, predict the sign of the entropy change for this reaction, why?(b) Using given values for AH°rxn, AS rxn,, solve for AGºrxn at 25.0 °C.AS rxn=+165.3 J/mol K+58.1 kJ/molΔΗAHOrxn(c) Is this reaction spontaneous at 25.0 °C? If so, find the temperature at which the reaction is nolonger spontaneous. If not, find the temperature above which the reaction is spontaneous.(Assume that the values of AH°rxn and AS rxn do not change appreciably with temperature).

The objective is to determine signs of the entropy change in the reaction, calculate the standard…

Consider the reaction of copper(I) oxide with carbon, which is used in a step during the extraction of copper metal from chalcocite: Cu₂0 (s) + C (s) → 2Cu (s) + CO (g) (a) Without doing any calculation, predict the sign of the entropy change for this reaction, why? (b) Using given values for AH rxn, AS rxn,, solve for AG rxn at 25.0 °C. AH°rxn +58.1 kJ/mol AS rxn = +165.3 J/mol K (c) Is this reaction spontaneous at 25.0 °C? If so, find the temperature at which the reaction is no longer spontaneous. If not, find the temperature above which the reaction is spontaneous. >-(Assume that the values of AH°rxn and AS rxn do not change appreciably with temperature).

Discuss the language demands included in the lesson on mixing substances in a 5th-grade classroom by Identifying key vocabulary terms students must know in order to master the learning objectives for the lesson based on the below standard and learning objective. Standard Conduct an investigation to determine whether the mixing of two or more substances results in new substances. Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.
