Química Inorgánica I
Práctica 1er parcial

RESPONDA CORRECTAMENTE EN CADA CASO:

1. ¿CUALES SON LAS VARIABLES QUE RELACIONEN EL CONCEPTO DE
DENSIDAD?

Significa que densidad (ρ) es igual a masa (m) entre volumen (v). De lo cual, además,
podemos deducir que la densidad es inversamente proporcional al volumen: mientras menor
sea el volumen ocupado por determinada masa, mayor será la densidad.

2. ENUNCIE LA LEY DE LAVOISIER
● La materia ni se crea ni se destruye, sólo se transforma.
● En una reacción química la suma de la masa de los reactivos es igual a la suma de
la masa de los productos.
● En una reacción química los átomos no desaparecen, simplemente se ordenan de
otra manera.

3. HALLE LA ENERGÍA CINÉTICA DE UNA MATERIA QUE TIENE UNA MASA DE 36
GRS. Y SE MUEVE A 4 CMS/SEG.

Datos

m = 36 gr = 0.036 Kg
V = 4 cm/Seg = 0.04 m/seg
Ec = ½ m.V²

Ec = ½ (0.0036 Kg)(0.04 m/seg)²
Ec = 0.5 (0.036 Kg)(0.0016 m/seg²)
Ec = 0.0000288 Joules


4. UN TROZO DE HIERRO OCUPA UN VOLUMEN DE 2.5 CC Y SU MASA ES DE 1280
GRS. CALCULE SU DENSIDAD

datos

M = 1,280 gr
V = 2.5 cm³

P = m/v
P = 1,280 gr/2.5 cm³
P = 512 gr/cm³
