Question

select all the correct answers. fireworks are chemical reactions that release energy. which of these phenomena are caused by chemical reactions that release energy? if you’re not sure, make a guess. muscles work to perform a task. fuel burns and heats the surroundings. a battery supplies current to a device. a car’s air bag expands by igniting a chemical.

Explanation:

Muscle work involves ATP hydrolysis (chemical energy release). Fuel burning is combustion (exothermic). Batteries use redox reactions for energy. Air bag expansion uses chemical ignition releasing energy. All are exothermic chemical reactions.

Answer:

Muscles work to perform a task, Fuel burns and heats the surroundings, A battery supplies current to a device, A car's air bag expands by igniting a chemical.
