Answer:
The oxygen will appear in the final stage if the oxygen is excess from the beginning.
Explanation:
1. C +(1/2)O2 —> CO
2. CO+(1/2)O2—> CO2
The first stage explains that the oxygen is limited and hence CO is produced.
The 2nd stage explains that if the oxygen is excess, then CO2 will be produced.
The overall reaction when oxygen is excess is given by:
C + O2 —> CO2
Answer:
semimetals or metalloids.
Explanation:
Answer: C2H4
Explanation:
The percentage composition of ethanol ( C2H5OH ) consist of 52.2% Carbon, Hydrogen of 13.0 and 34.8% of Oxygen.
The percentage composition of ethane gas (C2H6) consist of 80.0% carbon and 20.0% hydrogen.
The composition of Ethylene Glycols i.e C2H4(OH)2 is Carbon of 39.7%, 9.7% hydrogen and 51.6% oxygen.
The percent composition of c2h4 is 86% carbon, and 14% hydrogen.
From the information given, the substance with the highest percentage of carbon is C2H4
