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.
70%
Air consists of 78% Nitrogen and about 21% Oxygen. The remaining 1% is formed from other gases.
It is made up of 3% nitrogen.
Nitrogen makes up about 80% of the Earth's atmosphere.
Dinitrogen Pentoxide is made up of nitrogen and oxygen. The percentage of composition of each of these elements is: 25.936% nitrogen and 74.064% oxygen.
Nitrogen 78% , Oxygen 21%.
Carbon, hydrogen, oxygen and nitrogen atoms.
It is made when nitrogen and oxygen collide to make nitrogen dioxide
carbon nitrogen hydrogen oxygen
Silica is NOT made of nitrogen and oxygen. It is actually made of silicon dioxide which means it's made of silicon and oxygen.
The percentage of oxygen in the atmosphere is approximately 21%. Nitrogen makes up 78% and the last 2% percent is a mixture of various different gases, mostly argon.
Copper nitrate is a compound. It is made from oxygen, copper and nitrogen.
70 % hydrogen, 28 % Helium, 1.5 % mix of carbon oxygen, & nitrogen, plus 1/2 % of everything else.
78 percent Air is mostly gas The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
