What are the two main gases?
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
What are the 4 gases that make up earths atmosphere?
The four most abundant gases in Earth's atmosphere are nitrogen, oxygen, argon, and carbon dioxide. Nitrogen makes up about 78% of the atmosphere, oxygen around 21%, argon about 0.9%, and carbon dioxide less than 0.04%.
What is the human body mostly made of a carbon oxygen nitrogen and hydrogen b oxygen calcium carbon and hydrogen c hydrogen iron nitrogen and oxygen?
The human body is made up of only mostly carbon, oxygen, hydrogen, nitrogen, calcium, and phosphorus. The top four elements are oxygen, carbon, hydrogen and nitrogen, so that would be a. on your list.
The atmosphere is almost 80 percent what?
Nitrogen, with oxygen making up most of the remaining 20 percent. Other gases such as argon, carbon dioxide, and trace amounts of other gases make up the rest of the Earth's atmosphere.
What are the gases that make up our Earths atmosphere?
The main gases that make up Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include argon, carbon dioxide, and trace gases like neon, helium, methane, krypton, and hydrogen.
What is ninety-eight percent of the mass of every living organism composed of?
carbon, hydrogen, oxygen, nitrogen, phosphorus
What Ninety six percent of the human body is made of what elements?
Ninety six percent of the human body is made up of oxygen, carbon, hydrogen, and nitrogen. These elements are essential for life and play key roles in various biological processes in the body.
What four elements make up 96 percent of living organisms?
The four elements that make up 96 percent of living organisms are carbon, hydrogen, oxygen, and nitrogen. These elements are essential for building biological molecules such as proteins, DNA, and carbohydrates that form the fundamental structure of living organisms.
What four elements make up 96 percent of the human body?
The four elements that make up 96 percent of the human body are oxygen, carbon, hydrogen, and nitrogen. These elements are found in abundance in biological molecules such as water, proteins, carbohydrates, fats, and nucleic acids, which are essential for human life and function.
What is air made out of?
air is made of 19.98 percent oxygen 79 percent nitrogen and 2 percent carbon
What five elements comprise 99.5 percent of the human body?
Nothing. But the closest is water, which makes up about 60%.
What is made up of 62 percent Hydrogen 24 percent Oxygen 12 percent Carbon and 1 percent Nitrogen?
The atmosphere.
Why does air never fill up with carbon dioxide?
Ninety-nine percent of the atmosphere is already filled with nitrogen and oxygen, and carbon dioxide makes up less that 1% of the rest. So it will take a long time for the air to fill up with carbon dioxide.
What is 98.5 percent of bodys weight?
oxygen, carbon, hydrogen, nitrogen, phosphorous, and calcium.
What is over 99 percent of the atmosphere in pure dry air composed of?
Over 99 percent of the atmosphere in pure dry air is composed of nitrogen and oxygen, with nitrogen making up about 78 percent and oxygen around 21 percent. The remaining 1 percent is made up of trace gases such as argon, carbon dioxide, and neon.
Do carbon and nitrogen make oxygen?
No. Carbon, nitrogen, and oxygen are separate elements.
What proportion of the air is made up of carbon dioxide oxygen and nitrogen?
nitrogen is 78% while CO2 is part of a percent
