No. It is an element.
Oxygen is a pure gas that is mixed with other gases to produce the atmosphere to support human life. Deep sea divers use a mixture of oxygen and other gases to enable them to dive deep - it is a very important science. Our blood captures the oxygen we breathe in and binds it safely to the transport molecule called haemoglobin.

A mixture of gases contains 0.25 mol oxygen gas 0.75 mol nitrogen gas and 1.50 mol carbon dioxide gas at STP The mole fraction of oxygen gas in this mixture is?

At STP (Standard Temperature and Pressure), the volume occupied by 1 mol of any gas is 22.4 L. Thus, 0.25 mol of oxygen gas occupies (0.25 mol) * (22.4 L/mol) = 5.6 L in the mixture. The total volume of the gas mixture can be found as the sum of the individual volumes of oxygen, nitrogen, and carbon dioxide. Then, the mole fraction of oxygen gas is the moles of oxygen gas divided by the total moles of all gases in the mixture.


Is it true homogeneous mixture of nitrogen gas and oxygen gas will have the same chemical properties as a compound formed from nitrogen gas and oxygen gas?

No; the given statement is false. The natural atmosphere is largely a homogeneous mixture of oxygen and nitrogen gases, and it has very different chemical properties form any of the compounds formed from nitrogen and oxygen. Distinct such compounds with formulas N2O, NO, NO2, and N2O5 are known and are all chemically different from one another as well as from a homogeneous mixture of oxygen and nitrogen gases.


Is 15 grams of oxygen gas and 22 grams of nitrogen gas a mixture or a compound?

15 grams of oxygen gas and 22 grams of nitrogen gas together form a mixture, not a compound. A mixture is a physical combination of two or more substances that retain their individual properties, while a compound involves a chemical combination of elements in fixed ratios.


Is air a solid liquid or a gas?

Air is a mixture of gases, which includes nitrogen, oxygen, and smaller amounts of other gases. It is not a solid or a liquid.


Which of the following is a mixture of water vapor carbon dioxide oxygen gas salt water?

The mixture of water vapor, carbon dioxide, oxygen gas, and salt water is salt water. Salt water is a solution composed of water and salt (sodium chloride), along with some dissolved gases like carbon dioxide and oxygen.

Is condensation of oxygen gas a homogeneous mixture or heterogeneous mixture?

Neither. The condensation of oxygen gas is a phase change. The oxygen itself would be an element, not a mixture.

A mixture of gases contains 0.25 mol oxygen gas and 1.50 mol carbon dioxide gas at STP the mole fraction of oxygen gas in its mixture is?

The total moles of gas in the mixture is 0.25 + 1.50 = 1.75 mol. The mole fraction of oxygen gas is the moles of oxygen gas divided by the total moles, so 0.25 mol / 1.75 mol = 0.143. Therefore, the mole fraction of oxygen gas in the mixture is 0.143.


Is oxygen gas element compound or mixture?

Oxygen is a chemical element.


examples of a gas/gas solution that's not air?

Solutions in which solute and solvent both are gases; are called Gas-gas Solutions. For example - solution (mixture) of nitrogen and oxygen, solution (mixture) of carbon dioxide and nitrogen, solution (mixture) of carbon dioxide and oxygen, etc.


Is oxygen a heterogeneous mixture?

Oxygen is not a mixture at all. It is simply a gas in it's purest form. Mixtures are made of liquids and solids.


What is the composition of a mixture of hydrogen and oxygen?

A mixture of hydrogen and oxygen typically consists of hydrogen gas (H2) and oxygen gas (O2) molecules. The ratio of hydrogen to oxygen is usually 2:1, as per the chemical formula for water (H2O). This mixture is highly explosive and should be handled with caution.


What is the particial pressure of oxygen?

The partial pressure of oxygen is a measure of the pressure exerted by oxygen in a mixture of gases. In atmospheric air at sea level, the partial pressure of oxygen is around 160 mmHg. The partial pressure of oxygen can also be calculated using the equation: partial pressure of oxygen = total pressure of gas mixture * mole fraction of oxygen gas in the mixture.


Does a mixture of nitrogen oxygen and argon are a solution?

Such a gas-gas mixture is, technically, a solution but most people do not use that term to describe it.
