Air is composed of many different gasses, while water is a pure substance. Which choice best compares air and water? (1 point)
Air and water are both essential components of the Earth's environment.
A•Air is a compound of two or more components that keep their own identifying properties, while water is composed of mixtures that combine forming a compound.
B•Air is a compound of two or more components that keep their own identifying properties, while water is composed of elements that combine forming a mixture.
C•Air is a mixture of two or more components that keep their own identifying properties, while water is composed of elements that combine forming a
compound.
D•Air is a mixture of two or more components that keep their own identifying properties, while water is composed of compounds that combine forming a mixture.
D. Air is a mixture of two or more components that keep their own identifying properties, while water is composed of compounds that combine forming a mixture.
Are you sure explain
I apologize for the confusion in my previous response. Let me correct that.
The correct choice is C. Air is a mixture of two or more components that keep their own identifying properties, while water is composed of elements that combine forming a compound.
This is because air is a mixture of various gases (such as nitrogen, oxygen, carbon dioxide, etc.) that maintain their individual properties, while water is composed of hydrogen and oxygen atoms that chemically combine to form the compound water (H2O).
Are you correct explain further
I apologize for the confusion. Let's clarify further:
Air is a mixture of gases, primarily nitrogen (about 78%), oxygen (about 21%), and smaller amounts of other gases like carbon dioxide, argon, and trace gases. Each gas in the air maintains its individual properties and can be separated from the other gases in the mixture.
Water, on the other hand, is a compound composed of hydrogen and oxygen atoms that chemically bond together to form water molecules (H2O). This means that the elements hydrogen and oxygen combine in a fixed ratio to form a new substance with different properties than the individual elements.
So, the key difference is that air is a mixture of gases where each component maintains its own properties, while water is a compound where the elements combine to form a new substance with unique properties.
Alright and with that information what is that answer
The correct choice is:
C. Air is a mixture of two or more components that keep their own identifying properties, while water is composed of elements that combine forming a compound.
This best compares the nature of air (a mixture of gases) and water (a compound composed of hydrogen and oxygen atoms).
Jayla did an investigation about the different states of matter. As part of the investigation, she wanted to change a liquid into a solid. What must she do to bring about this change in state? (1 point)
•place the liquid in a different container
• increase the energy of the liquid so that its particles move faster
• remove energy from the liquid so that its particles slow down
• stir the liquid as quickly and thoroughly as possible
