Answer:

a) 9v

b) 90kv/m

c) 7.17pC

d) 9v

e) 29kv/m

f) 22.3pC

Explanation:

Capacitor's potential difference before the Mylar is inserted is

- The potential difference across the two plates is same as the voltage provided by the battery V = 9V which remains constant throughout.

The capacitor's electric field before the Mylar is inserted is, E = v/kd

E = 9 / 1*10^-4

E = 90000v/m

The capacitor's charge before the Mylar is inserted is, C = k*A*ε / d

C = 9*10^-6 * 8.85*10^-12 / 1*10^-4

C = 7.965*10^-13

C = 0.7965pF

Q = CV, 0.7965 * 9

Q = 7.17pC

Capacitor's potential difference after the Mylar is inserted, as stated earlier is constant at v = 9v

Capacitor's electric field after the Mylar is inserted, E = v/kd

E = 9/1*10^-4 * 3.1

E = 9/3.1*10^-4

E = 29032v/m

Capacitor's charge after the Mylar is inserted will be, C = k*A*ε / d

C = (3.1 * 9*10^-6 * 8.85*10^-12) / 1*10^-4

C = 2.47*10^-16 / 1*10^-4

C = 2.47*10-12

C = 2.47pF

Q = CV, = 9 * 2.47 = 22.3pC

1. Indica cuáles son los reactivos y productos de la reacción química representada por la ecuación siguiente, y señala en que es
bearhunter [10]

Answer:

Los reactivos, con su correspondiente estado de agregación, son:

  • Mg: estado sólido
  • HCl: estado acuoso

Los productos, con su correspondiente estado de agregación, son:

  • MgCl₂: estado acuoso
  • H₂: estado gaseoso

Explanation:

Una reacción química es un proceso por el cual una o más sustancias se transforman en otra u otras sustancias con propiedades diferentes. En otras palabras, las reacciones químicas son procesos en los que los átomos rompen sus enlaces químicos y forman otros nuevos, cambiando la naturaleza de las sustancias que intervienen.

En una ecuación química se representan dos términos. En el primero, el de la  derecha, se escriben los reactivos, expresados mediante sus fórmulas químicas  correspondientes y separados por un signo más. Por otro lado, el término de la izquierda, en  el que aparecen los productos, también representados por sus formulas químicas  correspondientes y con signos más entre ellos. Entre ambos términos suele ponerse  una flecha que indica que se ha producido la reacción química correspondiente.

Las sustancias que hay antes de producirse el cambio y que desaparecen se llaman reactivos. Las sustancias que hay después de producirse el cambio y que aparecen o se generan se llaman productos.

El estado de agregación en una reacción química se indica poniendo detrás del nombre o la fórmula de la sustancia y entre paréntesis la notación siguiente:

  • Sustancias sólidas (s)
  • Sustancias líquidas (l)
  • Sustancias gaseosas (g)
  • Sustancias disueltas en agua (aq)

En este caso tienes la reacción química:

Mg (s) + 2 HCl (aq) -> MgCl₂ (aq) + H₂ (g)

Entonces, <u><em>en este caso los reactivos, con su correspondiente estado de agregación, son:</em></u>

  • <u><em>Mg: estado sólido</em></u>
  • <u><em>HCl: estado acuoso</em></u>

<u><em>Por otro lado, los productos, con su correspondiente estado de agregación, son:</em></u>

  • <u><em>MgCl₂: estado acuoso</em></u>
  • <u><em>H₂: estado gaseoso</em></u>
