What is 2h2o dihydrate?
2H2O dihydrate typically refers to a chemical compound that contains two molecules of water (H2O) bound to another substance. The "dihydrate" suffix indicates the presence of two water molecules in the compound's structure.
The presence of which kind of molecules determines the concentration of other substance in the body?
Water
Flammability is a chemical property that tells whether a substance reacts in the presence of carbon dioxide.?
oxygen
Is flammability a chemical property that tells whether a substance reacts to the presence of carbon dioxide?
oxygen
What is the smallest intensity of an odor that can be detected by a human?
The nose can detect an odor from the presence of only a few molecules of substance.
What is the chemical activity of substance?
Chemical activity refers to the ability of a substance to undergo a chemical reaction when in contact with other substances. It is determined by factors such as the reactivity of the substance's molecules and the conditions in which the reaction occurs (e.g. temperature, pressure, presence of catalysts).
Is when it remains unchanged in the presence of nitrogen chemical or physical?
When a substance remains unchanged in the presence of nitrogen, it is likely due to its chemical inertness to nitrogen. This can be a result of the substance's molecular structure or its lack of reactivity with nitrogen molecules. Physical properties, such as solubility or vapor pressure, can also play a role in determining whether a substance remains unchanged in the presence of nitrogen.

Water
Effect of the presence of other molecules on the diffusion of a given substance?
The presence of other molecules can affect the diffusion of a given substance by changing the concentration gradient, which in turn affects the rate of diffusion. If other molecules are blocking the pathway or binding to the diffusing substance, diffusion may be slowed down. On the other hand, if the other molecules are helping to carry the diffusing substance, diffusion may be facilitated.
Why must you use chemical tests to reveal the presence of molecules?
Molecules are chemicals. A particular chemical posses a characteristic feature of forming an unique product when it undergoes chemical reaction along with another chemical. So to identify the chemical "A", one may use chemical "B" or "X" to react with chemial "A" to identify the formation of a product "AB" or "AX". This may many times evident by changes in color.
Is a substance's capacity to burn in the presence of oxygen and is an example of a chemical property.?
It is [in]flammability.
How can one determine the presence of a precipitate in a chemical reaction?
To determine the presence of a precipitate in a chemical reaction, one can look for the formation of a solid substance that appears cloudy or settles at the bottom of the reaction mixture. This solid substance is called a precipitate and indicates that a chemical reaction has occurred.
Why do we use iodine solution to test for starch and what is the significance of this chemical reaction in identifying the presence of starch?
Iodine solution is used to test for starch because it reacts with starch molecules to form a dark blue or black color. This chemical reaction is significant in identifying the presence of starch because it provides a visible and easily recognizable indication of the presence of starch in a substance.
Is flammability of a substance is physical or chemical change?
Stating that something is flammable is stating a chemical property. But the actual burning would be a chemical change.
Flammability is a chemical property that tells whether a substance reacts in the presence of carbon dioxide.?
oxygen
Is flammability a chemical property that tells whether a substance reacts to the presence of carbon dioxide?
oxygen
