Ungrupo ade estudiantes utilizan un aparato para estudiar la tranferencia de energia durante la tranferencia de energia durante la reaccion quimica entre pedaxos de cascara de huevo( carbono de calcio) y vinagre(acidoacetico). Durante el experimento utilizan la misma masa de cascara de hievo pero carian la concentracion del vinagre, (1%, 3% y 5%). Contesta:1. Explica por que la transferencia de energia no es la misma entre las tres pruebas del experimento.2. Describe como se podria modificar el aparato para que pueda medir con MAYOR EXACTITUD la tranferencia de energia en cada reaccion

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
