Question

Check whether for the given chemical reaction the given information holds true or not?
${C_4}{H_{10}}(g) + \dfrac{{13}}{2}{O_2}(g) \to 4C{O_2}(g) + 5{H_2}O(l);\vartriangle H = - 2878kJ$
$\vartriangle H$is the heat of combustion of butane gas. If true enter 1 else 0

Answer 1

Hint: Butane or n-butane with formula ${C_4}{H_{10}}$ is an alkane. At room temperature and ambient pressure, butane is a gas. Butane is extremely flame-retardant, colorless, easily liquefied gas that evaporates rapidly at room temperature. It is a hydrocarbon gas that is extracted from petroleum and is highly flammable gas. It is also an Alkane Series member. We also mix it with propane, and commercially use it as LPG (Liquefied Petroleum Gas). In addition, it is found in two forms: n-butane and isobutene. In addition, it's the N-butane where N stands for natural.

Complete answer:
Combustion heat is the amount of heat that developed when one mole of the material is completely burned in air or oxygen.
${C_4}{H_{10}}(g) + \dfrac{{13}}{2}{O_2}(g) \to 4C{O_2}(g) + 5{H_2}O(l);\vartriangle H = - 2878kJ$
1 mole of butane undergoes combustion in the reaction above. Therefore, $\vartriangle H$is the heat of butane gas combustion.

Note: Normal butane can be used for gasoline blending as a fuel gas, as a solvent for fragrance extraction, either alone or in a propane mixture, and as a feedstock for the manufacture of synthetic rubber, ethylene and butadiene. Isobutane is used mainly by refineries to raise (raise) the number of motor fuel octanes. It can be referred to commercially as LPG, for liquefied petroleum gas, when blended with propane and other hydrocarbons. It is used as a petrol component, as a feedstock in steam cracking to produce base petrochemicals, as a fuel for cigarette lighters, and as a propellant in aerosol sprays such as deodorants.
