Alexa is writing a paper comparing elements and compounds found in living and nonliving things. Which of the following could Alexa use to correctly describe the relationship between elements and compounds? *
A. Two compounds are required to make one element in natural systems.
B. Compounds combine in different ways to create many variations of elements.
C. There is a finite number of elements that can be used to create a multitude of compounds.
D. Every elements can be broken down into an infinite number of compounds.

Alexa is writing a paper comparing elements and compounds found in living and nonliving things. She would use the statement There is finite number of elements that can be used to create a multitude of compounds

Option (c) is correct

Explanation:.

Elements are the simplest substances and they cannot be broken further. But on the other hand, compounds are made when two or more elements combine together. Compounds can be easily broken by means of a chemical reaction.

Like if we say hydrogen and oxygen they are two different elements but when they combine together to form water than that water is called a compound. So in this way, a large number of compounds can be created by using various elements.

If we talk about atoms than we c.an say that elements are made up of one type of atoms like O₂ and S₈.But compounds are made up of two or more atoms like SO₄,H₂O etc.

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
