The negative ion reactions that consist of the formation of carbon dioxide in the atmosphere is generally an exothermic reaction. By definition, an exothermic reaction takes place when the chemical process eventually releases heat as its by-product. It is in contrast in endothermic process wherein heat is absorbed.

Answer:The reaction is exothermic.

Explanation:

Enthalpy of Formation (\Delta H_{rxn}): It is defined as change in enthalpy when one mole of substance is formed at standard temperature and pressure from its pure elements under same conditions.

1) \Delta H_{rxn}= negative

When the energy is released during formation of compound in a chemical reaction that is an Exothermic reaction.

2) \Delta H_{rxn}= positive

When the energy is absorbed during the formation of compound in a chemical reaction that is an Endothermic reaction

The \Delta H_{rxn}of formation of carbon dioxide is negative means that the reaction is exothermic reaction.

If a compound has a molar mass of 180 g/mol and its empirical formula is CH2O, what is its molecular formula? CH2O C2H4O2 C6H12O
irinina [24]

Its molecular formula : C₆H₁₂O₆

<h3>Further explanation  </h3>

The empirical formula(EF) is the smallest comparison of atoms of compound forming elements.  

A molecular formula(MF) is a formula that shows the number of atomic elements that make up a compound.  

(EF) n = MF

its empirical formula is CH₂O

CH₂O : 12+2+16=30

\tt [30]n=180\rightarrow n=6\\\\(CH_2O]_6=C_6H_{12}O_6
