Answer:
The Equilibrium constant K is far greater than 1; K>>1
Explanation:
The equilibrium constant, K, for any given reaction at equilibrium, is defined as the ratio of the concentration of the products raised to their stoichiometric coefficients divided by the concentration of reactants raised to their stoichiometric coefficients.
It tells us more about how how bigger or smaller the concentration of products is to that of the reactants when a reaction attains equilibrium. From the given data, as the color of the reactant mixture (Br2 is reddish-brown, and H2 is colourless) fades, more of the colorless product (HBr is colorless) is being formed as the reaction approaches equilibrium. This indicates yhat the concentration of products becomes relatively higher than that of the reactants as the reaction progresses towards equilibrium, the equilibrium constant K, must be greater than 1 therefore.
Answer:
a. C5H12 + O2 → CO2 + H2O
c) Mg + O2 → MgO
Explanation:
Una reacción de combustión es definida como una reacción en la que un elemento o compuesto reacciona con oxígeno para producir un óxido y liberar calor.
Cuando un hidrocarburo (De fórmula general CₓHₙ) entra en combustión, dióxido de carbono y agua son producidos.
Así, las reacciones que corresponden a combustión son:
a. C5H12 + O2 → CO2 + H2O
<em>Se produce dióxido de carbono y agua</em>
c) Mg + O2 → MgO
<em>Se produce óxido de magnesio y se libera calor.</em>

Answer:
at constant pressure the enthalpy change of a process equal the amount of heat transferred into or out of the system
Explanation:
∆H=∆(E+PV)
=∆E+P∆V
∆E=qp+w
w=P∆V
∆H=∆E+P
∆V=(qp+w)-w=qp
when qp= heat at constant pressure
good luck
