What happens when burning magnesium ribbon is inserted into the Jar of carbon dioxide ​

when Mg burn it react with oxygen and form MgO ,now the oxygen is witin the Mg and that is why a burning magnesium ribbon continues to burn when put in a jar filled up of carbon dioxide.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
