What are the 4 main components of air in their molecular form?
Nitrogen
Oxygen
Argon
Carbon Dioxide
You're right! Thank you!
Which of the following statements is true?
The square root of the molecular weight of a gas is equal to its rate of diffusion.
The rate of diffusion of a gas in inversely proportional to the square root of its molecular weight.
The rate of diffusion of a gas is directly proportional to the square root of its molecular weight.
The square root of the molecular weight of a gas is not related to its rate of diffusion.
The rate of diffusion of a gas in inversely proportional to the square root of its molecular weight.
Which of the following gases is the heaviest?
O 2 , CH 4 , CO 2 , Cl 2
Sorry, that one I don't know
The fourth one
Thank you for your help Auriana and Lily
The four main components of air in their molecular form are nitrogen (N2), oxygen (O2), carbon dioxide (CO2), and trace amounts of other gases such as argon, neon, and helium. To understand how these components make up the air, you can use the concept of atmospheric composition.
To determine the molecular components of air, you need to understand the Earth's atmosphere and its composition. Here's how you can find the answer:
1. Understand the Earth's atmosphere: The Earth's atmosphere is a layer of gases that surrounds the planet. It is primarily composed of nitrogen, oxygen, and other trace gases.
2. Look for reliable sources: Consult reputable sources such as scientific textbooks, educational websites, or official government publications that provide information about atmospheric composition.
3. Learn about the main gases: Nitrogen is the most abundant gas in the Earth's atmosphere, comprising about 78% of the total volume. Oxygen is the second most abundant gas, making up approximately 21% of the atmosphere. Carbon dioxide is a minor component, accounting for about 0.04% of the atmosphere. The remaining gases, such as argon, neon, and helium, are present in trace amounts.
4. Verify the information: cross-reference multiple sources to ensure accuracy and validity. This helps to confirm that nitrogen, oxygen, carbon dioxide, and trace gases are indeed the main molecular components of air.
By following these steps, you can find the answer to your question and understand how to determine the molecular components of air.
