Which two substances must be present for an iron object to rust?
For the oxidation of iron to occur, that is for ferric oxide to form, there must be oxygen present. There must also be water present.
Which common atoms are present in present?
Carbon, Hydrogen, Oxygen and Nitrogen.
What is the rock that makes up white cliffs of dover?

Is this true or false The pyruvic acid produced in electrolysis enters the chloroplasts if the oxygen is present in a cell?
It is false that if oxygen is present in a cell, pyruvic acid in glycolysis enters the chloroplasts. The pyruvic acid enters the mitochondria if oxygen is present in a cell.
How do you test oxygen using a splint test?
To test for the presence of oxygen using a splint test, you first burn a splint until it smolders. Then, you blow out the flame and introduce the smoldering splint into the gas being tested. If oxygen is present, the splint will reignite due to the oxygen supporting combustion.
Which acid or base is present in chalk powder?
Chalk is neutral.
Compound element of chalk?
Chalk is primarily composed of calcium carbonate, which is a chemical compound. Calcium carbonate is made up of calcium, carbon, and oxygen atoms in a specific ratio, giving chalk its characteristic properties.
What are the elements present in chalk?
Chalk is predominantly calcium carbonate. Therefore, its elements are calcium, carbon, and oxygen.
Hydrogen peroxide reaction with chalk?
When hydrogen peroxide (H2O2) reacts with chalk (calcium carbonate, CaCO3), the chalk acts as a catalyst to break down the hydrogen peroxide into water (H2O) and oxygen (O2) gas. This reaction produces bubbles of oxygen gas as a result of the decomposition of hydrogen peroxide.
When oxygen is not present?
there is no oxygen present in the electron transport system.
When oxygen not present?
there is no oxygen present in the electron transport system.
What element is the metal part of chalk also present in bones and teeth?
The metal part of chalk, calcium, is also present in bones and teeth. Calcium is an essential mineral for the structure and strength of bones and teeth.
Is chalk an element?
If you mean the sedimentary white rock, then that is Calcium Carbonate which has the elements Calcium, Carbon and Oxygen. If you mean blackboard chalk, then that is Calcium Sulphate which has the elements Calcium, Sulphur and Oxygen.
How many elements are in chalk?
Chalk is composed mainly of calcium carbonate and calcium sulfate, both of which are chemical compounds. So, chalk does not have a fixed number of elements, as it consists of multiple elements bonded together to form these compounds.
Oxygen is not present in other planets?
Yes Oxygen is present in other planets.
Is their oxygen where coal present?
no there is not
What elements compounds make up limestone chalk and cement?
Limestone, chalk, and cement primarily consist of calcium carbonate. Limestone and chalk are composed mainly of this compound, while cement typically contains a mixture of calcium silicates, aluminates, and ferrites that are produced by heating limestone and other materials together.
