Select from the frequently asked questions below
- Chemistry problems that involve enthalpy changes can be solved by techniques similar to stoichiometry problems.
- The moles of a reactant or product can be linked to mass or volume.
- Since pollution is often both particulate and thermal, energy changes need to be determined in addition to the amounts of products released.
- The calculation requires two steps.
- The mass of SO2 is converted to moles.
- Then the mol SO1 is multiplied by the conversion factor of .
- The result is the energy released by the reaction of sulfur dioxide and oxygen.
The thermochemical equation for the reaction of methane combustion CH4(g)+2O2(g)→CO2(g)+2H2O(l) + 890.4 kJ is known. What amount of methane substance is consumed in the release of 89.6 kJ of heat?
