Ammonia is a weak base because produce ____ ion in solution?

Ammonia is a weak base ( electrolyte) because ammonia reacts with water to produce ammonium and hydroxide ions. When hydroxide ion reacts with ammonium, it results to water and ammonia. it only proves that ammonia is rather a base because of its acceptance of hydrogen ion from water.

Ammonia is a weak base because it produces ammonium and hydroxide ions. Weak bases are so called weak because in the solution, these bases do not fully convert itself into hydroxide ions or in other words, it does not fully ionize in the solution.

The radiation per unit area from the Sun reaching the earth is 1400 W/m2 , approximately the amount of radiative power per unit

Answer:

83.2 W/m^2

Explanation:

The radiation per unit area of a star is directly proportional to the power emitted, which is given by Stefan-Boltzmann law:

$P=\sigma A T^4$

where

$\sigma$ is the Stefan-Boltzmann constant

A is the surface area

T is the surface temperature

So, we see that the radiation per unit area is proportional to the fourth power of the temperature:

$I \propto T^4$

So in our problem we can write:

$I_1 : T_1^4 = I_2 : T_2^4$

where

$I_1 = 1400 W/m^2$ is the power per unit area of the present sun

$T_1 = 5800 K$ is the temperature of the sun

$I_2$ is the power per unit area of sun X

$T_2 = 2864 K$ is the temperature of sun X

Solving for I2, we find

$I_2 = \frac{I_1 T_2^4}{T_1^4}=\frac{(1400 W/m^2)(2864 K)^4}{(5800 K)^4}=83.2 W/m^2$

Explanation:

PRIMERO HACES EL RECUENTO DEL TIEMPO Y LO CONVIERTES EN

SEGUNDOS Y ENTONCES

<em>t</em> = 227 s $t_{AB}$ = 227 S - 38 s = 189 s

$t_{BC}$ = 38 s

LUEGO USANDO LA ECUACIÓN DE GALILEO GALILEI SSUPONIENDO

QUE EL MOVIL VIAJA A VELOCIDAD CONSTANTE

<em>v</em> = 3.50 m/189 s = 0.0185 m/s

PARA LA DISTANCIA NTRE B Y C

$x_{BC}$ = 0.0185 m/S( 38 s) = 0.703 m

LA HORA EN QUE EL MOVIL PASA POR A ES

11:43:15 - 38 s - 189 s = 11:39:29

In an inelastic collision, as compared to an elastic collision, what is to be expected?.

motikmotik

The loss or conservation of kinetic energy is the difference between an elastic and an inelastic collision. Kinetic energy is not preserved in an inelastic collision, and it will change forms into sound, heat, radiation, or another form. The kinetic energy in an elastic collision is preserved and does not change forms.
