Answer:
Exothermic, it obeys the law of conservation of energy
Explanation:
The reaction is an exothermic change. In this kind of change, heat is liberated to the surrounding. So the surrounding becomes hotter at the end of the heat change.
In chemical reactions that involves the loss of energy as heat, they obey the law of conservation of energy.
The law of conservation of energy states that energy is neither created nor destroyed but transformed from one form to another. In such reactions as this, chemical energy is transformed into heat energy.

have a wonderful day! do good in school you got this! :)
Answer:
64
Explanation:
Distance traveled in 2 hours = 2 * 40 = 80 m
Distance traveled in 3 hours = 3 * 80 = 240m
Total distance covered = 240 + 80 = 320m
Total time = 2 + 3 =5 h
Hence avg speed = total distance covered / total time taken
= 320/5 = 64mph
Answer: True
Air is a mixture of many things; it's not just Oxygen, but Hydrogen, Carbon, and Nitrogen as well are made up of air. Fun fact: Nitrogen is actually more abundant in air
Answer:
Albert Einstein is perhaps most famous for introducing the world to the equation E=mc2. In essence, he discovered that energy and mass are interchangeable, setting the stage for nuclear power—and atomic weapons. His part in the drama of nuclear war may have ended there if not for a simple refrigerator.
