The given questions belongs to the concept of limiting reagent.

The number of moles of carbon dioxide produced when 4.6 moles of dioxygen reacts is 4.6 moles.

<h3 /><h3>What is Limiting Reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed.

Given ;

Moles of Oxygen = 4.6

To find;

Moles of Carbon di oxide = ?

The reaction that forms CO_2 is as follows:

C(s) + O_2(g) -->  CO_2(g)

This means that O_2 is consumed and  CO_2 is produced in a 1:1 ratio.

If we consume 4.6 mol  O_2, then we produce 4.6 mol  CO_2 .

Hence, 4.6 mol  CO_2 are produced when 4.6 mol of oxygen reacts.

Para solucionar el ejercicio primero se debe conocer el número atómico de los elementos para determinar cuantos electrones tiene
Jet001 [13]

Answer:

El número atómico se refiere al número de protones o electrones de un átomo.

Explicación:

El número atómico se refiere a la cantidad de protones o la cantidad de electrones que giran alrededor de las capas u órbita de un átomo, por lo que el número atómico 7 representa que el átomo tiene 7 electrones o protones mientras que, por otro lado, el número atómico 17 muestra el número de electrones o protón. Solo hay dos electrones que entran en la primera órbita y en el resto de las capas tiene espacio para 8 electrones por lo que los átomos pierden o agregan electrones en su capa más externa para obtener estabilidad.
