Answer:
The second part of the Dalton's atoms
theory says all atoms of a given element are identical in mass and properties.
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
is as follows:
C(s) +
(g) -->
(g)
This means that
is consumed and
is produced in a 1:1 ratio.
If we consume 4.6 mol
, then we produce 4.6 mol
.
Hence, 4.6 mol
are produced when 4.6 mol of oxygen reacts.

Ionic bonds are the weakest bonds.
Answer:
1. This reaction is <u>(A) Exothermic .</u>
2. When the temperature is decreased the equilibrium constant, K: <u>(A) Increases</u>
3.When the temperature is decreased the equilibrium concentration of Co2:<u> (A) Increases</u>
Explanation:

1. The pink color predominates at low temperatures, indicating that the commodity is preferred.
This is a reaction that is <u>exothermic.</u>
2. As the decrease in the temperature , the equilibrium constant , K ;
equilibrium constant =
=![\frac{[CO^2^+][Cl^-^4]}{CoCl^2^-_4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BCO%5E2%5E%2B%5D%5BCl%5E-%5E4%5D%7D%7BCoCl%5E2%5E-_4%7D)
As the temperature drops, the concentration of
and
rises, and K rises as well , thus it <u>increases </u>.
3. The equilibrium concentration of
decreases as the temperature decreases:
When the temperature is lowered, the equilibrium shifts to the right , that is it <u>increases.</u>
