Question

In the chemical reactions of chemosynthesis, microscopic organisms use heat and inorganic compounds to produce food for themselves. What type of chemical reaction is chemosynthesis? A. unbustion B. exothermic C. combustion D. endothermic

Answer 1

D. endothermic

Explanation:

Since the reaction uses up heat, we can conclude that it is an endothermic enthalpy change.

• Enthalpy changes are heat changes that accompanies physical and chemical changes.
• In an endothermic change, heat is usually absorbed from the surroundings hence the surrounding becomes colder at the end of the changes.
• The heat energy level of the reactants is lower than that of the product.
• In an exothermic change, heat is liberated to the surroundings. The surrounding then becomes hotter at the end of the change. Example of such a reactions is combustion.
