How can you prove that water contain oxygen?

Water have two atoms of hydrogen and one atom of Oxygen. As the aquatic animals are able to live in water, they inhale and exhale in water. It proves that water has oxygen so that they are alive.

How can you prove water is a hydrogen compound?

1. Water is formed by the chemical bond between 2 hydrogen and one oxygen atom.
2. A bond between atoms of water can be broken by chemical reaction.
3. Atoms of water cannot be separated by the physical process.
4. Hence, water is a compound because it can only be separated into hydrogen and oxygen atom by chemical reaction.

How can you study experimentally that water is made of hydrogen and oxygen combined together in the ratio of 2 1 by volume?

If we take some water in a beaker and add sulphuric acid to it then it becomes acidulated water and a great conductor of electricity. Then we pass electric current through them and we see that one test tube has more space than the other. This proves that water has 2 parts of hydrogen and 1 part of oxygen.

What is the oxygen content of water?

Oxygen concentrations are much higher in air, which is about 21\% oxygen, than in water, which is a tiny fraction of 1 percent oxygen.

How will you prove that water is transparent?

Just take a glass of water and make sure that the glass is transparent. And now take a torch and pass the light through it. This shows that water is transparent as light passes through it without scattering. Thus, Water is transparent.

Which two reasons to prove that water is a resource?

-The melting point of water as well as boiling point varied on the external pressure, volume and surrounding temperature. This implies that water is a compound and not an element. This is because an element’s properties remain uniform irrespective of external conditions. -Water is stable at room conditions.

How will you confirm water is a compound?

Water is considered to be a compound due to the following reasons : (i) Water cannot be separated into its constituents hydrogen and oxygen by physical methods. (ii) Properties of water are entirely different from its constituents hydrogen and and oxygen. Hydrogen is combustible while oxygen supports combustion.

How hydrogen gas is prepared in the laboratory?

Hydrogen is prepared in the laboratory by the action of the dilute hydrochloric acid or dilute sulphuric acid on granulated zinc. Granulated zinc gives more surface area for the acid to act, so hydrogen is formed faster.

Which of the following property does not proves that water is a compound A the ratio of hydrogen and oxygen by mass in water is fixed ie1 8?

Answer: property does not prove that water is a compound is d) Distilled water and tap water have same taste and constituents.

How is hydrogen made water?

Luckily water (H2O) contains hydrogen and we can use water to produce hydrogen gas (H2). Splitting water molecules into oxygen gas and hydrogen gas using electricity is called “electrolysis”. Through electrolysis, we convert electrical energy into a storable fuel namely hydrogen gas.

How can we identify test the gas in test tube is hydrogen or oxygen?

Tests for gases

1. Hydrogen, oxygen, carbon dioxide, ammonia and chlorine can be identified using different tests.
2. Hydrogen. A lighted wooden splint makes a popping sound in a test tube of hydrogen.
3. Oxygen. A glowing wooden splint relights in a test tube of oxygen.

How do you make water from hydrogen and oxygen gas?

2 H 2 + O 2 → 2 H 2O. In theory, it’s easy to make water from hydrogen gas and oxygen gas. Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto—instant water.

What is the ratio of hydrogen to oxygen in water?

To make matters worse, any experiment is going to be subject to experimental error, so any ratios that are slightly off—say, a ratio of 15 hydrogen atoms to 8 oxygen atoms as measured by experiment due to hydrogen diffusing through the container you try to hold it in—makes for a very complicated structure for water that is laughably incorrect.

What happens when hydrogen is burned in oxygen?

Hydrogen fuel experiment Hydrogen burns in oxygen to form water. hydrogen + oxygen → water 2H2 + O2 → 2H2O

What is the balanced chemical equation for the synthesis of water?

The molecule is produced from numerous chemical reactions, including the synthesis reaction from its elements, hydrogen, and oxygen. The balanced chemical equation for the reaction is: 2 H 2 + O 2 → 2 H 2O. In theory, it’s easy to make water from hydrogen gas and oxygen gas.
