Yes fuel gives off CO2!
Any Hydrocarbon produces CO_2 when combusted. The only fuel that does not produce CO_2 when combusted is Hydrogen
carbon dioxide
Water is given off when fuels are burnt in oxygen
The gas given off by photosynthesis is oxygen, plants take in carbon dioxide and generate it into oxygen.
Carbon Dioxide
There are two, oxygen and carbon dioxide. Oxygen is produced by photosythensis, which is done only during the daytime. Carbon dioxide is given off by cellular respiration, which is done all the time. Overall, more oxygen is given off then carbon dioxide.
The exchange of oxygen and carbon dioxide between the lungs and bloodstream is known as respiration. This process occurs in the alveoli of the lungs, where oxygen is taken in and carbon dioxide is removed from the blood.
Carbon dioxide
carbon dioxide and oxygen are given off
In lungs where carbon dioxide is released and oxygen absorbed and in cells where oxygen is given to cells and carbon dioxide is absorbed by blood.
Carbon Dioxide
The gas given off as a waste product of photosynthesis is oxygen. Glucose is also made during photosynthesis. These products are made from carbon dioxide and water.
It will take O2 gas. It will emit CO2 in the night.
