Given the thermochemical expression BaO (s) + CO2 (g) =
BaCO3(s)
AH° = -662.8 kJ
Write the thermochemical expression for the production of 4 mol CO2 by decomposition of solid
barium carbonate.

Explanation:

Hello,

In this case, in order to answer to the requirement, we first should invert the given reaction since it is the formation of barium carbonate and we need its decomposition:

Thereby, the enthalpy of reaction is inverted, to positive since it is the contrary reaction:

Nevertheless, we need to specify it for the formation of 4 moles of carbon dioxide it means:

Which finally results in the following thermochemical expression:

Regards.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.
