Quick Answer: Is Oxygen A Liquid Or Gas - SeniorCare2Share

Explanation: Oxygen ( O2 ) is a gas at room temperature (273 K). It is a liquid at 90 K and a solid at 54 K. How do you make oxygen gas? To make oxygen in the laboratory, hydrogen peroxide is poured into a conical flask containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water.

Why are ionic compounds solid at room temperature? | …

They are solids because the particles which make up ionic compounds are held together by very strong bonds. Ionic compounds are formed when atoms of different charges (i.e. positive and negative ions) come together and form ionic bonds. These ionic bonds are typically very strong due to the high attractive forces holding the positively and negatively charged ions …

Explain why CO2 is a gas while SiO2 is a solid at room ...

Explain why CO2 is a gas while SiO2 is a solid at room temperature. Post Answer. Answers (1) A Ankit Dutt. Carbon dioxide is a linear structure with two double bonds between carbon and oxygen. It is a small molecule and non-polar with only weak bonds between the molecules. Hence it is a gas. Silicon dioxide is not formed of small molecules. ...

Explain why bromine is a liquid at room temperature while ...

This is because Bromine has stronger inter-molecular forces due to a bigger atomic radius than chlorine. Therefore Bromine is a liquid at room temperature because it requires more energy to break the forces than chlorine which has a lower melting and boiling points since less energy is required to break the forces.

Liquid metals at room temperature: Physics Today: Vol 74, …

The ability to print liquid metals at room temperature is enticing because the metal can be incorporated into structures with plastics, elastomers, and other temperature-sensitive materials. The surface oxide that forms on liquid metals causes the materials to adhere to most surfaces, a property that is necessary for maintaining a printed shape.
