The balanced equation below shows the products that are formed when pentane (C5H12) is combusted. C5H12 + 8O2 mc029-1.jpg 10CO2
Maru [420]

Answer: The mole ratio of oxygen to pentane for the combustion of pentane is 8 : 1.

Explanation: The given reaction is a type of combustion reaction.

Combustion reaction is a reaction in which a hydrocarbon reacts with oxygen gas to produce water and carbon dioxide gas.

For the reaction of pentane with oxygen, the balanced equation would be:

C_5H_{12}+8O_2\rightarrow 5CO_2+6H_2O

In the reaction, 1 mole of C_5H_{12} reacts with 8 moles of O_2 gas.

Thus giving us the mole ratio as

Oxygen : Pentane = 8 : 1

Write the equilibrium-constant expression for the reactionA(s)+3B(l)↽−−⇀2C(aq)+D(aq)A(s)+3B(l)↽−−⇀2C(aq)+D(aq)in terms of [A], [
Ilia_Sergeevich [38]

Answer:

K_{c} = [\text{C}]^{2}[\text{[D]}

Explanation:

\rm A(s)+3B(l) \, \rightleftharpoons \, 2C(aq)+D(aq)

The general formula for an equilibrium constant expression is

K_{c} = \dfrac{[\text{Products}]}{[\text{Reactants}]}

Solids and liquids are not included in the equilibrium constant expression.

Thus, for this reaction,  

K_{c} = [\textbf{C}]^{\mathbf{2}}\textbf{[D]}
