Select the most likely product for this reaction: koh(aq) + co2(g) – ? k2co3(aq) + h2o(1) k(s) + h2(g) + o2(g) k(s) + co3(9) +h2

K2CO3(aq) + H2O(l)

Explanation:

Balance the equation

2KOH(aq) + CO2(g) K2CO3(aq) + H2O(l)

K2CO3(aq) + H2O(1)

Explanation:

KOH(aq) + CO2(g) is an acid-base reaction.

KOH is a known base and CO2 is a known acidic gas. It dissolves in water to give a solution whose pH is less than 7.

The normal products of a neutralization process is the salt and water. Hence, this neutralization process isn't any different. Salt, in the form of K2CO3, and water, H2O is the result of this reaction.

a:

by the combination of an unlimited number of elements

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
