Chemical Composition and Structure:
* Formula: CH4 (one carbon atom bonded to four hydrogen atoms)
* Molecular Weight: 16.04 g/mol
* Structure: Tetrahedral, with the carbon atom at the center and the hydrogen atoms at the corners.
Physical Properties:
* State: At room temperature and pressure, methane is a colorless, odorless gas.
* Density: 0.717 kg/m3 (at 0°C and 1 atm)
* Boiling Point: -161.5 °C (-258.7 °F)
* Melting Point: -182.5 °C (-296.5 °F)
Amount and Volume:
* Moles: 16.0 grams of methane corresponds to approximately 1 mole (since the molecular weight is close to 16 g/mol).
* Volume: At standard temperature and pressure (STP), 1 mole of any ideal gas occupies 22.4 liters. Therefore, 16.0 grams of methane would occupy approximately 22.4 liters at STP.
Important Note: The volume of methane would change significantly depending on the temperature and pressure.
Reactivity:
* Flammable: Methane is highly flammable and forms explosive mixtures with air.
* Greenhouse Gas: Methane is a potent greenhouse gas, contributing to climate change.
Uses:
* Fuel: Methane is a major component of natural gas and is used as a fuel for heating, electricity generation, and transportation.
* Chemical Feedstock: It serves as a raw material in the production of various chemicals, including methanol and hydrogen.
Additional Information:
* 16.0 grams of methane is a relatively small amount.
* The description above provides a general overview of the properties and characteristics of this amount of methane.
* It is important to handle methane with care due to its flammability and potential environmental impact.
