Iodine would have chemical properties most like Fluorine, Chlorine and other elements in group 7
When you add all of the numbers together, it equals 136.41. that divided by 3 = 45.47 which is the average
Rubidium is a chemical element with symbol Rb and atomic number 37. Rubidium is a soft, silvery-white metallic element of the alkali metal group, with a standard atomic weight of 85.4678. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidationin air. On Earth, natural rubidium comprises two isotopes: 72% is the stable isotope, 85Rb; 28% is the slightly radioactive 87Rb, with a half-life of 49 billion years—more than three times longer than the estimated age of the universe.
aluminum element is more reactive than rubidium (Rb)
Energy production
Thus most industries in working burn oxygen as fuel. Examples are steel production and production of chemicals
Answer:
2.01 A
Explanation:
Para esta pregunta debemos empezar por la semi-reaccion del plomo:
Se intercambian dos electrones en la semi-reacción del plomo. Si tenemos en cuenta la ecuación:
Donde:
<u>n= Moles depositados </u>
<u>I= Intensidad de corriente (en Amperios)</u>
<u>z= Numero de electrones intercambiados</u>
<u>F= Constante de faraday = 96484 C/mol</u>
<u>t=tiempo (en segundos)</u>
Que conocemos de esta ecuación?
<u>Los moles (se pueden calcular a partir de la masa atómica del plomo, 207.2 g/mol)</u>
<u>El tiempo (hay que convertirlo a segundos):</u>
<u>Z (Numero de electrones)</u>
De acuerdo a la semi-reacción son intercambiados 2 electrones.
<u>Por lo tanto podemos resolver para "I":</u>
Espero que sea de ayuda!
