Estimate the production of CO2 and CH4 during the anaerobic decomposition of ethanol. C2H6O.

64Cu can decay by both decay and + decay. Draw an appropriate portion of a Segr plot along the lines of Figure 5.3 showing these two decay processes.

Cellulose is to be burned in a waste-to- energy fadlity. The chemical equation for cellulose C6 H10O5is the atomic weights of C, H, and O are 12, 1, and 16. respectively. a. Calculate the stoichiometric oxygen necessary for the combustion of cellulose. b. Calculate stoichiometric air.
