Answer:
no it is not a balanced equation
It is the first option bc if it absorbed heat it it will pressurize and could explode.
The balanced combustion reaction for one mole of ethane will be
C2H6 + 3.5 O2 ---> 2CO2(g) + 3H2O (l)
Enthalpy of reaction of combustion = ∑ΔHf (products)- ∑ΔHf (reactant)
ΔHf = enthalpy of formation
The enthalpy of formation of oxygen = 0 as it is an element in its native state
ΔHf C2H6 = -83.820 kJ / mole
ΔHf H2O = -285.830 kJ / mole
ΔHf CO2 = -393.509 kJ / mole
ΔHrxn = [2 X ΔHf CO2 + 3 X ΔHf H2O] - [ΔHf C2H6]
ΔHrxn = [2 X (-393.509) + 3 (-285.830)] - [-83.820]
ΔHrxn = -1560.688 kJ / mole
Answer:
the pH of the solution expresses the concentration of hydrogen ion in the solution. By measuring the pH value of a solution helps us to define the acidity or basicity of the solution. If the pH value in the pH scale is greater than 7 then the solution is basic
