"A reaction in aqueous solution is run in a calorimeter and it is found that the the solution gains 98 kJ of heat and the calorimeter gains 3 kJ of heat. What is the heat gained or lost by the reaction (qrxn) in kJ

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
