Oxygen gas supports combustion?Oxygen gas is odourless, tasteless, and colorless gas denser than the air… Complete step-by-step answer: Combustion is also called burning in which substance or fuel burn in presence of the oxygen.
Who invented oxygen gas?The French chemist Antoine Lavoisier later claimed to have discovered the gas independently of Priestley. He named it oxygen (meaning ‘acid maker’), and investigated its properties. However, it’s known that Priestley had already shown Lavoisier how to make oxygen, undermining his claim.
How do you increase the solubility of a gas?An increase in pressure and an increase in temperature in this reaction results in greater solubility. An increase in pressure results in more gas particles entering the liquid in order to decrease the partial pressure. Therefore, the solubility would increase.

How does temperature affect solubility of gas in liquid?
As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return to the gas phase. Therefore, the solubility of a gas decreases as the temperature increases.
How can the solubility of a gas be increase quizlet?At a given temperature the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. As the pressure of the gas above the liquid increases, the solubility of the gas increases.

How does pressure affect the solubility of gases in liquids?
- The solubility of a gas depends on the pressure. An increase in pressure increases solubility, whereas a decrease in pressure decreases the solubility. This is summarized in Henry's law, which states that solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.
Solubility of a gas in liquid depends upon nature of gas, temperature of gas and nature of solvent.
What are the factors that affect the solubility of gases?- Gases as Solvent If Gases as a solute needs to be dissolved in a solvent, there are factors influencing solubility, such as temperature, nature of solvent and solute, and pressure. There can be several gas solutes which can readily dissolve in solvent whereas few gas solutes which do not dissolve under normal conditions.

What two factors can change the solubility of a gas?
- The reaction is exothermic, so an increase in temperature means that solubility would decrease.
- The change in solubility cannot be determined from the given information. Increasing pressure increased solubility, but increasing temperature decreases solubility
- An increase in pressure and an increase in temperature in this reaction results in greater solubility.
- An increase in pressure results in more gas particles entering the liquid in order to decrease the partial pressure. Therefore, the solubility would increase.
The solubility of a gas in a liquid will increase if: Lower the temperature of the solution , and therefore, lower the kinetic energy of the gaseous particles so they can escape the liquid phase less often.
Why does the solubility of a gas increase with temperature?- There are several molecular reasons for the change in solubility of gases with increasing temperature, which is why there is no one trend independent of gas and solvent for whether gases will become more or less soluble with increasing temperature. Increasing pressure will increase the solubility of a gas in a solvent.
To find the duration, you first have to convert liquid oxygen into a gaseous oxygen equivalent, because the liquid will expand when it evaporates into a gas. Liquid oxygen expands into gaseous oxygen at a rate of 860:1, which is why it is so efficient to deliver oxygen in liquid form.
Do electric eels need oxygen?Electric eels are obligatory air breathers. They receive almost 80 percent of their oxygen through their highly vascularized mouth.
Does electric heater need oxygen?- Heating will have no effect on the oxygen level in the air unless something First Degree Burn Condition where the superficial cells of the epidermis are injured. , which will use up oxygen. This is basic chemistry. An electrical heater heats because electrical current passes through it, not because anything burns, so oxygen levels cannot be directly affected.
However, the burning of methane or hydrogen requires oxygen… Many chemical reactions that require oxygen seem to just happen automatically on earth: metals rust, forests catch fire, and candles burn.
Does oxygen react with methane?When methane (CH4) reacts with oxygen it forms carbon dioxide and water. Here we notice that the reaction is not balanced as the number of hydrogen atoms are different on each side.

Is methane heavier than oxygen?
Methane is lighter than air, colourless and, despite what you might think considering animals burp it out, odourless.
Is oxygen a colourless gas?The most plentiful element in the Earth's crust, about 46.6 percent by weight, oxygen is a nonmetallic element which, in its pure form is a colorless, odorless, tasteless gas.
Is oxygen a corrosive gas?The presence of significant quantities of oxygen in addition to water and electrolytic environments can cause dramatic corrosion reactions to occur on a metallic surface. Some corrosion prevention methods such as coating, painting or blanketing can be used to reduce the metal surface's exposure to oxygen in a corrosive environment.
Is oxygen a dry gas?By volume, dry air typically consists of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, and 0.04% carbon dixoide. Usually, air also contains small but variable amounts of water vapor, which takes up on average 1% of volume at sea level.
Is oxygen a gas 2?Oxygen is an element. At standard temperature and pressure, oxygen is a gas. The boiling point of oxygen occurs at -183 degrees celcius, which means that it will be a gas above this temperature, or a liquid or solid below this temperature.
Is oxygen a noble gas?Those of you who remember the tedious hours expended in learning chemistry on the pathway to a medical degree may recall the noble gases from the periodic table — helium, argon, krypton, xenon,...
