The structure and mass of trees (or logs) comes primarily from cellulose, long chains of glucose (C6H12O6) molecules. Glucose molecules in the log burn according to the balanced chemical equation: 6 CO2 + 6 H2O yields C6H12O6 + 6 O2 What is true regarding mass when burning a log? A. If the log were burned in a closed container, the mass of the system would remain constant B. If the log were burned in a closed container, the mass of the system would decrease because the gases produced are lighter than solid log C. If the log were burned in an open container, the mass of the system would appear to decrease because gases are lost to the surroundings D. Both a and c E. Both b and c
