The heat of neutralization of hcl(aq) and naoh(aq) is -55.90 kj/mol of water produced. if 50.00 ml of 1.16 m naoh at 25.15ºc is added to 25.00 ml of 1.79 m hcl at 26.34ºc in a plastic-foam cup calorimeter, what will the solution temperature be immediately after the neutralization reaction has occurred?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
