Identify the oxidation numbers for all the elements in the reactants and products for 2mno4−(aq)+3s2−(aq)+4h2o(l)→3s(s)+2mno2(s)
Sidana [21]

The oxidation number if eah of the elements is as follows;

  • Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
  • Oxidation number if hydrogen is +1 on both sides
  • The oxidation number of oxygen is -2 on both sides
  • The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.

<h3>What is a redox reaction?</h3>

A redox reaction is one in which there is a change in the oxidation number of the reactants from left to right.

Let us now consider the oxidation  number of each element from left to right;

  • Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
  • Oxidation number if hydrogen is +1 on both sides
  • The oxidation number of oxygen is -2 on both sides
  • The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.

QUESTION 17 - 1 POINT
Triss [41]

Answer:

PREGUNTA 17 - 1 PUNTO

Se sabe que leer un nombre en voz alta puede mejorar la memoria. A un psicólogo le gustaría probar la afirmación de que los adultos pueden

recordar más del 55 por ciento de los nombres de una lista, en promedio, después de leer la lista en voz alta. Para probar esta afirmación en el

nivel de significación, el psicólogo recopila los siguientes datos en una muestra de 50 participantes y registra el porcentaje de

nombres recordados en la lista después de leerla en voz alta. Los siguientes son los datos de este estudio:

Tamaño de la muestra = 50 participantes

Media de la muestra = 60 por ciento

A partir de datos anteriores, se sabe que la desviación estándar de la población es del 15 por ciento.

Trabaje con el procedimiento de prueba e interprete los resultados de la prueba de hipótesis. ¿Cuál es tu conclusión?

No se puede rechazar la hipótesis nula. NO hay pruebas sólidas para concluir que los adultos pueden recordar más

del 55 % de los nombres de una lista, en promedio, después de leer la lista en voz alta.

No se puede rechazar la hipótesis nula. Existe una fuerte evidencia para concluir que los adultos pueden recordar más que

los nombres en una lista, en promedio, después de leer la lista en voz alta.

Rechazar la hipótesis nula. NO hay evidencia sólida para concluir que los adultos pueden recordar más de 5

nombres en una lista, en promedio, después de leer la lista en voz alta.

Rechazar la hipótesis nula. Existe una fuerte evidencia para concluir que los adultos pueden recordar más del 55%

de los nombres en una lista, en promedio, después de leer la lista en voz alta.
