Combines with hydrogen and oxygen to form carbohydrates?

Carbohydrates are composed of hydrogen, oxygen, and carbon. They can be considered hydrates of carbon. Common carbohydrates include monosaccharides, disaccharides, oligosaccharides, and polysaccharides.

Oxygen+ 2 hydrogen= water

Hydrogen combines with oxygen when burned, forming H2O (water).

When Hydrogen is burned in air it combines with Oxygen to form water. 2H2 + O2 -> 2H2O

No. Carbohydrates do contain hydrogen and oxygen, but not in the form of individual water molecules.

Hydrogen is a colorless gas that combines with oxygen when burned to form water.

No, carbohydrates do not contain water. They do have oxygen and hydrogen but not in the form of water molecules. The name carbohydrates means watered carbon.

Carbohydrates contain carbon, hydrogen, oxygen and nitrogen.

No. Water is made of one oxygen atom, and two hydrogen atoms. (H2O)

Hydrogen combines with oxygen to form water. The reaction is two molecules of hydrogen gas (H2) and one molecule of oxygen gas (O2) to form two molecules of water (H2O).

Two hydrogen atoms and one oxygen atom combine to form one water molecule.

Methane is made up of one carbon atom and four hydrogen atoms. When methane burns, the carbon in the methane combines with oxygen (O) to form carbon dioxide (CO2). The hydrogen in the methane combines with oxygen to form H2O, or water.

Free hydrogen is not normally found in air, since it combines explosively with oxygen.

Both oxygen and hydrogen are necessary to form carbohydrates. The hydrogen to oxygen ratio is 2 to 1, just like with water. The explains the basis for the name carbohydrate which is watered carbon.

To get the hydrogen to form carbohydrates, plants break down water into hydrogen and oxygen. This also provides electrons that drive the light-dependent reactions. The oxygen is released into the atmosphere.

Carbohydrates are made of carbon, and contains hydrogen and oxygen atoms. Carbon is the base atom and oxygen, and hydrogen is bonded to the carbon. The ratio of hydrogen to oxygen is 2:1.Carbohydrates consist of the elements carbon (C), hydrogen (H) and oxygen (O) with a ratio of hydrogen twice that of carbon and oxygen. Carbohydrates include sugars, starches, cellulose and many other compounds found in living organisms. In their basic form, carbohydrates are simple sugars or monosaccharides. These simple sugars can combine with each other to form more complex carbohydrates. The combination of two simple sugars is a disaccharide. Carbohydrates consisting of two to ten simple sugars are called oligosaccharides, and those with a larger number are called polysaccharides.

Do you mean when combined? Because when Hydrogen gas (H2) is burned it combines with Oxygen (O2) to form Water (H2O). The extra oxygen is used to make another molecule of water. So two molecules of oxygen are needed and four molecules of Hydrogen.

One of the most common examples is water which is composed of the element hydrogen and oxygen.

It is a colorless , odorless, flammable gas that combines chemically with oxygen to form water: the lightest of the known elements....

if u are asking about the living cells most cell parts are made of carbon, hydrogen, oxygen and nitrogen with few other elements. the carbon and hydrogen mainly combine to form carbohydrates and fats while carbon, hydrogen, oxygen and nitrogen join to form proteins. Carbohydrates , fats & proteins form most parts of the cells....

When hydrogen burns in air, it combines with atmospheric oxygen to form water. Since hydrogen and oxygen are undergoing a chemical change to become chemically bonded together producing H2O the change is chemical in nature.

A chemical reaction because a new substance if produced. :)
