BIOCOMBUSTIBLES

1. Raw materials used for biofuel production, such as crops, residues, or organic waste.
3. Is the total heat content of a system, denoted by the symbol "H."Stoichiometry: The calculation of reactants and products in chemical reactions based on balanced equations, helping determine quantities and relationships in a reaction.
5. The conversion of sugars into alcohol or organic acids by microorganisms, often used in biofuel production.
6. Derived from vegetable oils or animal fats, biodiesel is an eco-friendly alternative to traditional diesel fuel.
9. Microbial breakdown of organic matter to produce biogas, a process common in anaerobic digesters.
10. Microscopic aquatic plants that can be used to produce biofuels due to their high oil content.
12. Energy sources that can be replenished naturally, like solar, wind, and bioenergy.
13. Processes involving the use of heat to convert biomass into biofuels, such as gasification and pyrolysis.
15. Chemical reaction converting fats or oils into biodiesel and glycerol.
17. Thermal decomposition of biomass in the absence of oxygen, producing bio-oil, gas, and biochar.
19. Refers to a type of combustible material that remains in a solid state at room temperature and is used as a source of energy through combustion
20. Refers to biofuels made from non-edible plant materials like wood, grass, or agricultural residues.
21. The process of converting biomass into a gaseous fuel, like synthesis gas

2. The calculation of reactants and products in chemical reactions based on balanced equations, helping determine quantities and relationships in a reaction.
4. Alcohol produced by fermenting sugars, commonly used as a biofuel for vehicles.
7. Refers to plant materials rich in cellulose and lignin, often used in the production of advanced biofuels.
8. A chemical reaction that absorbs heat from its surroundings, resulting in a decrease in temperature.
11. A chemical reaction that releases heat to its surroundings, causing an increase in temperature.
14. Chemical process breaking down complex molecules into simpler ones using water, commonly used in biofuel production.
16. Are solid, liquid, or gaseous materials that release energy through a process called combustion, which releases energy into an oxygenated environment
18. Are those renewable fuels that are obtained through natural resources or organic waste, both animal and plant
