The change in enthalpy for the reaction of carbon dioxide is -393.5 kJ/mol. Thus, option A is correct.
The change in enthalpy of the reaction is given by the energy of the product and the energy of reactant difference.
The chemical equation for the reaction is:

<h3>Computation for the enthalpy change</h3>
The standard enthalpy change for carbon dioxide is -393.5 kJ/mol
The standard enthalpy change for oxygen is 0 kJ/mol
The change in enthalpy of reaction is given as:

Answer:
elements tend not to react with other elements, there were no oxide compounds for Mendeleev to study. –Group 18 elements are generally unreactive. sodium ion is smaller because the sodium atom lost one electron. –An Na+ ion is smaller because it has one fewer electron shell.
Explanation:
can you me as brainliest if its right? i just need a few more to rank up! ^-^
Also have a great day and good luck in your studies!
Answer:
An ideal gas is a gas with particular characteristics.
Explanation:
- The particles have no volume
- All collisions between particles are elastic collisions and lose no kinetic energy
- The particles neither attract each other nor repel
- They have random movement
Ideal gases are hypothetical which means that they do not exist in their true form.
hope this helps, pls mark brainliest :D
Using the formula 2n² put in the value of n which is 4
the answer is 2×4² which is 2×16
The answer is 32.
this is the maximum no of electron acceptable into the electron shell.

Answer:
Option C. 13.5 atm
Explanation:
From the question given above, the following data were obtained:
Pressure of Neon (Pₙₑ) = 4.1 atm
Pressure of Argon (Pₐᵣ) = 3.2 atm
Pressure of nitrogen (Pₙ₂) = 6.2 atm
Total pressure (Pₜ) =?
The total pressure in the container can be obtained by adding the pressure of the individual gases. This is illustrated below:
Pₜ = Pₙₑ + Pₐᵣ + Pₙ₂
Pₜ = 4.1 + 3.2 + 6.2
Pₜ = 13.5 atm
Therefore, the total pressure in the container is 13.5 atm
