Environmental Chemistry Assignment
To course of sure metallic ores, reactions with carbon can typically generate the pure metallic at excessive temperatures. Take into account the response of zinc oxide with carbon: ZnO + C - Zn + CO; AH = 240 kJ/mol How a lot warmth must be absorbed by the system (inkl) to react 3103 g of ZnO with 328 g of C till the response is accomplished? You have got 5 makes an attempt at this query. TIP: To report a solution in scientific notation, enter it utilizing the format "2.3E4", which suggests "2.three x 104" (with out the citation marks) Reply: Choose the suitable phrases which describe the character of AH (with respect to the system) in every state of affairs at fixed strain. a. System absorbs warmth, work carried out on the system b. System absorbs warmth, work carried out by the system on the environment.. c. System emits warmth, work carried out on the system. d. System emits warmth, work carried out by the system on the environment.
