What effect of the gas oxygen on lime water?
When oxygen gas is added to lime water (a solution of calcium hydroxide), it reacts with the calcium hydroxide to form calcium carbonate, which is white and insoluble in water. This reaction causes the lime water to turn milky.
When electricity is added to water water breaks down and becomes hydrogen gas and oxygen gas. This is a chemical change because?
The nature of the reactant (water) was changed.
Water is split and oxygen is released during which process?
Water is split and oxygen is released during the process of photosynthesis. In photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose and oxygen. The oxygen is released as a byproduct into the atmosphere.
Why heavy water is so called?
Heavy water is composed of deuterium, a heavier isotope of hydrogen with an extra neutron. This extra neutron increases the mass of the water molecule, leading to a higher density compared to regular "light" water. This is why it is called heavy water.
What do you call process the process when oxygen can be dissolved in water?
The process of oxygen dissolving in water is called "oxygenation." This occurs when oxygen molecules interact and become dispersed within the water molecules resulting in oxygen being absorbed by the water. It is essential for aquatic life and is influenced by factors such as temperature and pressure.
What happens to the concentration of oxygen in water when the sewage is added?
The concentration of oxygen decrease.
What happens to the concentration of oxygen in the water when the sewage is added?
The concentration of oxygen decrease.
How does water get oxygenated?
Oxygen can become dissolved in water.
How is the formula for water different than the formula for hydrogen peroxide?
Water is H2O. Hydrogen peroxide is H2O2. Hydrogen peroxide has one more oxygen atom per molecule than water. The extra oxygen is what makes it a peroxide. "Hydrogen oxide" would be water. The extra oxygen also makes hydrogen peroxide much more reactive than water due to the unstable oxygen-oxygen bond.
How does oxygen get into water for fish to breathe?
Oxygen partially dissolves in water. Respiratory systems of aquatic animals are adapted to get this dissolved oxygen. They have gills for respiration.
How does oxygen gas become dissolved in water?
By condensation
What is plain water maid of?
Hydrogen and Oxygen if you have added absolutely nothing to it.
How can you tell there is more oxygen in hydrogen peroxide than in water?
You can tell that there is more oxygen in hydrogen peroxide than in water because hydrogen peroxide has an extra oxygen atom compared to water. The chemical formula for hydrogen peroxide is H2O2, while the formula for water is H2O. This extra oxygen in hydrogen peroxide makes it a more oxidizing chemical compared to water.
How can hydrogen be added to water?
Hydrogen can be added to water through a process called electrolysis, where an electric current is passed through water to separate it into hydrogen and oxygen gases.
How do you add an extra oxygen molecule to water?
To add an extra oxygen molecule to water, you would need to introduce a second water molecule to the chemical reaction. This can be achieved through a process called electrolysis, where an electric current is passed through water, causing it to split into hydrogen and oxygen gases. The reaction can be represented as 2H2O --> 2H2 + O2.
When some kinds of antacid tablets are added to water the resulting fizz gives off oxygen gas true or false?
When some kinds of antacid tablets are added to water,the resulting fizz gives off oxygen gass.True
What happen to salt to ice water when added?
the salt dissolves and the water will become salt water
