Oxygen gas is mixed with hydrogen gas will it produce a substance or a mixture why WHY?

Hydrogen (H2) and oxygen (O2) are both elements. When you mix them and let it react (careful: explosive combustion!) in the right molecular ratio (2:1, cf. bold reaction equation) you get a new substance formed, known by its common name: water (H2O) and no H2 or O2 left behind.
So this water is a pure substance and not a mixture (= more than one substances mixed together)
Equation:
2 H2 + 1 O2 --> 2 H2O

∙ 6y agoThe compound (water) is formed by chemical bonds between H and O.
The mixture hasn't chemical bonds.

How does a mixture of hydrogen and oxygen differ from a compound of hydrogen and oxygen?
A mixture of hydrogen and oxygen means that the two gasses would be mixed together, but remain chemically distinct from one another and retain their own properties. You would still have separate hydrogen and oxygen molecules. In a compound of hydrogen and oxygen, water, the two elements are chemically combined to form a new substance with its own set of properties.
Is oxygen a homogeneous or heterogeneous mixture?
Neither. Oxygen is an element, which is a pure substance and not a mixture.
Is air a mixture of hydrogen and oxygen gases?
No. Air is a mixture made mostly of nitrogen and oxygen. A mixture of hydrogen and oxygen would be unstable. A spark or sufficient heat source would ignite the mixture and form water.
Is water vapor a mixture or pure substance?
Water vapor is a gas, not a mixture. Water vapor is just the gas form of water, it is not a mixture.Water Vapor is a compound made by bonding Hydrogen and Oxygen.
When a substance is combined with oxygen the substance is?
Often it's an oxide. For example, carbon burns in air to form its oxides, carbon monoxide and carbon dioxide. However, there are other possibilities. Hydrogen burns in oxygen to produce water.
What substance will you produce when you combine hydrogen and oxygen?
water
Is hydrogen and oxygen atoms that make up water a homogeneous mixture?
No. When in the form of water, hydrogen and oxygen form a compound, which is a pure substance.
Is hydrogen peroxide a pure substance or a mixture?
Mixture, because it is mixed with all sorts of chemicals, such as smog, and or pollen.Mixture is NOT a pure substance, because to be a pure substance, it can't be mixed with anything.
Does hydrogen and oxygen atoms from a mixture called water?
No. Water is a compound of hydrogen and oxygen, not a mixture.

Is oxygen a homogeneous or heterogeneous mixture?
Neither. Oxygen is an element, which is a pure substance and not a mixture.
Is a compound simply a mixture of two or more elements?
No. A mixture of elements would just be a mixture. The components of the mixture would remain chemically distinct. In a compound the elements are chemically bound to one another and behave as a single substance with its own set of properties. As an example, water (H2O) is a compound of hydrogen and oxygen that is liquid at room temperature. If you simply mix together hydrogen and oxygen, all you have is a mixture of gasses that will explode if exposed to a spark. This reaction will produce water vapor.
Is the hydrogen and oxygen atoms that make up water an example of homogeous mixture?
No. Since the hydrogen and oxygen in water are chemically bonded to one another in a fixed ration water is considered a pure substance.
Will a oxygen gas mixed with hydrogen gas produce substance?
If there is a source of activation energy, or in the presence of an active catalyst, these elements will react to produce water.
Are hydrogen and oxygen a compound or mixture in water?
In water, two hydrogen are covalently bonded to one oxygen making it a compound not a mixture.
Is oxygen mixture?
Oxygen is an element, which is a pure substance.
Give reason water is a compound and not a mixture?
A compound is defined by a substance in which the elements that it is made of are in a fixed ratio. In this case the ratio between the hydrogen and oxygen in 2:1. A mixture is a substance in which the elements that make it are not in a fixed ratio
