Hydrogen

Air is a mixture of different gases such as nitrogen, oxygen, carbon dioxide, and others. Since it is a mixture, it does not have a specific chemical formula like a compound would. Instead, the composition of air is typically given as a percentage of the different gases present.
When brass is dissolved in acid, the gases released may include hydrogen gas (H2) and potentially carbon dioxide (CO2) if carbonates are present in the brass alloy. The exact composition of gases released can vary depending on the specific acid and composition of the brass.
The composition of a comet is frozen gases, dust, and rocks.
Nitrogen makes up about 78% of the Earth's atmosphere, while oxygen makes up about 21%. The remaining 1% consists of other gases such as argon, carbon dioxide, and trace amounts of other gases.
Hydrogen Thank you
Hydrogen & helium
To present a pie chart showing the gases in air, you can divide the chart into sections representing the percentage of each gas in the air composition. Label each section with the name of the gas and its corresponding percentage. Displaying the relative sizes of the sections will visually represent the composition of gases in air.

Two gases that probably existed in Earth's early atmosphere are ammonia and methane. These gases were likely present in significant quantities before the atmosphere transformed into its current composition.
The two most common gases in dry air are nitrogen (N2) at approximately 78% and oxygen (O2) at around 21% of Earth's atmosphere composition.
The stratosphere is composed mostly of nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include ozone, water vapor, and trace gases like helium and methane. The exact percentages can vary slightly depending on altitude and location.
78% nitrogen, 21% oxygen, 1% water vapor, and i forget the rest
The composition of a comet is frozen gases, dust, and rocks.
