1. El metodo cientifico pretende sistematizar el proceso de obtención del conocimiento cientifico, evitar la subjetividad en los
____ [38]

Answer:

La afirmación es verdadera.

Explanation:

El método científico es un método de  investigación usado principalmente en la producción de conocimiento en las ciencias y se define como un procedimiento para tratar un conjunto de problemas. En ciencia, el método científico es la estrategia para la investigación y la exploración de lo desconocido.

Por lo que el método científico es el procedimiento mediante el cual es posible alcanzar un  conocimiento objetivo de la realidad, tratando de dar respuesta a las interrogantes  acerca del orden de la naturaleza.

Para ser científico, un método de investigación debe basarse en la empírica y en la  medición, sujeto a los principios específicos de las pruebas de razonamiento.

El método científico se basa en la reproducibilidad, es decir, la  capacidad de repetir un determinado experimento, en cualquier lugar y por cualquier  persona, y la refutabilidad,  es  decir toda proposición científica tiene que ser susceptible de  ser falsada o refutada.

Entonces <u><em>la afirmación es verdadera.</em></u>

12. A voltaic cell consists of a chromium electrode dipped in a 1.20 M chromium (III) nitrate
Lilit [14]

For a voltaic cell consisting of chromium, an electrode dipped in a 1.20 M chromium (III) nitrate solution and a tin electrode dipped in a 0.400 M tin (II) nitrate solution, the cell potential at 298 K  is mathematically given as

Ecell = 0.577 V

<h3 /><h3>What is the cell potential at 298 K?</h3>

Generally, the equation for the Oxidation and Reduction  is mathematically given as

Cr(s) ------------------ Cr+3(aq) + 3e- ] x 2 ...O

Sn+2(aq) + 2e- ------------ Sn(s) ] x 3  ...R

Reaction

 2 Cr(s) + 3 Sn+2(aq) --------------- 2 Cr+3(aq) + 3 Sn(s)

Therefore

Eicell = - 0.14 - ( - 0.74)

Eicell = 0.60

In conclusion

Ecell= E0cell - \frac{0.0591}{n} * \frac{log[Cr+3]^2}{ [ Sn+2]^3}

Ecell = 0.60 - \frac{0.0591 }{6} \frac{log( 1.20)^2}{ ( 0.200)^3}

Ecell = 0.577 V

For the reaction, X + Y → A + B, ΔGo is –1324 kJ. Which one of the following statements is NOT valid concerning the reaction?
natima [27]

Answer:

c. The reaction will proceed rapidly from left to right.

Explanation:

The variation of the free Gibbs energy doesn't tell anything about the speed of reaction.

On the other hand, when ΔGo is negative: the reaction is spontaneous, thermodynamically favourable, and the products are more stable than the reactants
