Mamont248 [21]3 years ago

None of the given statements are completely true.

<u>Explanation</u>:  

Family or groups in "periodic table" are 18 in number which represents column in table. As we go down in a family or group in the "periodic table"-the atom size become bigger and bigger. Non-Metals are less reactive which mostly lie in p-block. "Metals" are ""ore reactive" in "s-block". The atom’s valence electrons remain same for example when we go down in alkali metals in s-block the valence electron is one only and in alkaline earth metals its two only.

Klio2033 [76]

Answer:

La pregunta no es clara, asi que voy a dar una breve descripicion de la termodinamica y alguno de los fenomenos que estudia

La termodinámica es la rama de la física que estudia los sistemas en equilibrio termodinámico (es decir, aquellos sistemas que no pueden sufrir un cambio espontáneo). Particularmente, la termodinámica estudia los procesos de flujo de calor (lo podemos ver en su nombre, dinámica del calor) y se relacionan estos cambios de energía con el trabajo que es posible obtener.

Entonces, por ejemplo, la termodinámica estudia como el hielo puede cambiar de fase (a medida que aumenta su temperatura) y convertirse en agua líquida.

La termodinámica también estudia como funcionan máquinas de calor, como motores de pistones, y el trabajo que estos son capaces de realizar.

Como ejemplo final, con la termodinámica podemos estudiar cosas tan complejas como equilibrio entre distintas fases (por ejemplo, el porqué podemos tener agua y hielo en equilibrio termodinámico, un ejemplo de esto son las superficies de ríos que se congelan mientras la parte inferior sigue siendo líquida)

Esos son, entre muchísimos otros, 3 posibles efectos que suceden a nuestro alrededor, y son estudiados por la termodinámica.

If the concentration of fluoride anion and aluminum cation was increased to 5 m, by how much would the measured ecell change?.
ladessa [460]

If the concentration of fluoride anion and aluminum cation was increased to 5M, then there would be decrease in Ecell by 0.055 volts

The standard reduction potential of Fluoride anion and aluminum cation are -

2Al -----> 2Al3+ + 6e-           E^ocell = +1.66

6e- + 3F2 -----> 6F-               E^ocell = +2.87

The complete reaction is -

2Al + 3F2 ------> 2Al3+  +  6F-    E^o = +4.53

Using Nernst Equation :-

E = E^o – 0.0592/n*log[Al3+]^2[F-]^6

n = 6 (n = number of transferred electrons)

E = +4.53 - 0.0592/6*log(5)^2(5)^6

E = +4.53 - 0.00987*log(25)(1.56 x 10^4)

E = +4.53 – 0.00987*log(3.9 x 10^5)

E = + 4.53 -0.00987(5.59)

E = + 4.53 - 0.055

E = +4.47

The change in Ecell = 5 - 4.47 = 0.055V

Given: Z = 0.43Y + 12 ; What is Y when Z = 28 ?<br> Can someone explain this one?
ss7ja [257]
Z=0.43y+12=28=0.43y+12=28-12=0.43y=16=0.43y,then u divide 0.43y by itself and by 16,you will get y=37.209
