Answer:
The correct option is: a chemical reaction between carbohydrates and oxygen to produce carbon dioxide, water, and heat energy
Explanation:
Respiration refers to the catabolic reactions in the cells that produce energy in the form of adenosine triphosphate (ATP) from various nutrients.
An aerobic respiration, is a spontaneous process that involves the use of <u>molecular oxygen (O₂) to produce energy (ATP). In this process, molecular oxygen oxidizes nutrients such as carbohydrates, fats, and proteins; to give carbon dioxide, water and heat energy</u>.
Hello!
The greatest negative impact of a new hydroelectric dam is the changes in the surrounding landscape.
Hydroelectric dams are among the cleanest energy sources, they don't generate waste, pollutants or atmospheric emissions. The negative impact is given by the landscape transformation needed to take advantage of the natural conditions of the dam. They stand out wherever they are, so it is important to consider the aesthetic aspect when building a dam.
Have a nice day!

Answer:
The heat of vaporization of water is 2257-J/g - each grams must release 2257-J of thermal energy. When water condenses its temperature remains constant.
Q = m x Hv ===> 50-g x 2257-J/g = 112,850-J = 112.9-kJ
