Un grupo de estudiantes utilizan un aparato para estudiar la tranferencia de energia durante la reaccion quimica entre pedazos d
e cascara de huevo( carbono de calcio) y vinagre(acido acetico). Durante el experimento utilizan la misma masa de cascara de huevo pero varian 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
A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%). Answer:
1. Explain why the energy transfer is not the same between the three tests of the experiment.
2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.
An improper fraction is a fraction in which the numerator (top number) is greater than or equal to the denominator (bottom number). Fractions such as 65 or 114 are “improper”.
