The combustion of the fatty acid called stearic acid has the  the complete equation; C18H36O2(s) + 26O2(g) ------> 18CO2 (g) + 18 H2O(g)

<h3>What is combustion?</h3>

The term combustion has to do with the burning of a substance in air. For organic compounds, we get carbon dioxide and water as the products.

Thus, for the combustion of the fatty acid called stearic acid, the complete equation is; C18H36O2(s) + 26O2(g) ------> 18CO2 (g) + 18 H2O(g)

Jobisdone [24]

Answer:

0.595

Explanation:

Let's consider the decomposition of hydrogen chloride.

2 HCl(g) ⇄ H₂(g) + Cl₂(g)

The pressure equilibrium constant (Kp) is equal to the product of the partial pressure of the products raised to their stoichiometric coefficients divided by the product of the partial pressure of the reactants raised to their stoichiometric coefficients.

Kp = pH₂ × pCl₂ / pHCl²

Kp = 77.9 × 54.4 / 84.4²

Kp = 0.595
