WebWays of determination Gross and net. Zwolinski and Wilhoit defined, in 1972, "gross" and "net" values for heats of combustion. In the gross definition the products are the most stable compounds, e.g. H 2 O (l), Br 2 (l), I 2 (s) and H 2 SO 4 (l). In the net definition the products are the gases produced when the compound is burned in an open flame, e.g. H 2 O (g), Br WebVerified answer. chemistry.

The table of specific heat capacities gives the volumetric heat capacity as well as the specific heat capacity of some substances and engineering materials, and (when applicable) the molar heat capacity. Generally, the most notable constant parameter is the volumetric heat capacity (at least for solids) which is around the value of 3 megajoule per cubic meter per kelvin: WebJan 30, 2024 · Solution. Step 1. First use stoichiometry to solve for the number of moles of CO 2 produced. ( 2 m o l C 2 H 6) ( 4 m o l CO 2 2 m o l C 2 H 6) = 4 m o l CO 2. So 4 moles of Carbon Dioxide are produced if we react 2 moles of ethane gas. Step 2.
