Chemistry

lesantik [10]3 years ago
5 0

La primera instrucción es verdadera, la segunda es falsa porque dos elementos no pueden tener el mismo número de masa (excepto azufre y argón) Estrictamente hablando, No. Puede tener 2 (o más) elementos con el mismo 'número de masa atómica', lo que significa que el número total de nucleones (neutrones de protones) es el mismo. En el ejemplo dado en una respuesta anterior, el azufre tiene un isótopo con el número de masa atómica 36 (16p 20n) y Argón también tiene un 36 (18p 18n). La tercera declaración es verdadera, si tiene un número diferente de neutrones, entonces es un isótopo. La cuarta declaración es falso. Espero que esto te ayude.

Which atom has a change of oxidation number of +4 in the pictured redox reaction?
SpyIntel [72]

Answer:

The answer to your question is the letter d. S

Explanation:

Data

Change of +4 in the oxidation number

Chemical reaction

               K₂Cr₂O₇  +  H₂O  +  S  ⇒   KOH  +  Cr₂O₃  +  SO₂    

Process

1.- Calculate the oxidation numbers following the rules.

Some rules

  H = +1       O = -2    Alkali metals = + 1    Alkali earth metals = +2    

K₂⁺¹Cr₂⁺⁶O₇⁻²  +  H₂⁺¹O⁻²  +  S⁰  ⇒   K⁺¹O⁻²H⁺¹  +  Cr₂⁺³O₃⁻²  +  S⁺⁴O₂⁻²    

Elements that changed their oxidation numbers

                       Cr₂⁺⁶   ---------------- Cr₂⁺³

                       S⁰       --------------- S⁺⁴
