Which liquid floats on top water or kerosene?
When water and kerosene are mixed kerosene will float on top.
Why is sodium stored in kerosene and not water?
Because it will react violently in water producing hydrogen gas in a highly exothermic reaction which often causes ignition of the hydrogen gas liberated: 2Nas + 2H2Ol --> H2,g + 2(NaOH)aq The kerosene used for storage must be importantly water free, or anhydrous, otherwise this reaction will also occur but more slowly. This is often exploited to remove trace water from organic solvents for chemical synthesis.
Which among kerosene and glycerin is miscible in water?
Glycerin is miscible in water, while kerosene is not. Glycerin is a polar molecule with hydrogen bonding capabilities, allowing it to mix well with water. Kerosene is non-polar and hydrophobic, so it does not mix with water.
Which metal is kept immersed in kerosene for storing?
Sodium is a metal that is commonly kept immersed in kerosene for storing because it reacts violently with water and oxygen in the air. Placing it in kerosene helps prevent these reactions and keeps the metal stable.
Can spirit and kerosene mix?
Water (H2O) and kerosene (C12H26) do not mix, i.e. they are not miscible. This is due to H20 being polar and C12H26 being different, that is non-polar, through the concept of "like dissolves like."
What chemical equation for kerosene mixed to water?
They will NOT react, so no chemical equation. (Mixing is NOT chemical, besides these two won't mix homogeneously!
Which liquid floats on top water or kerosene?

Metals react with water violently Is this a physical or a chemical property?
it is a chemical property

Why sodium is kept in kerosene?
Sodium metal reacts violently with water, and is stored in kerosine (for example) to avoid contact with moisture in the air.

How do the changes that occur when water is mixed with salt differ from the changes that result when water is mixed with sodium?
When water is mixed with salt, the salt dissolves in the water to form a solution. This process involves the breaking of the ionic bonds between the sodium and chloride ions in the salt. When water is mixed with pure sodium, a chemical reaction occurs, resulting in the formation of sodium hydroxide and hydrogen gas. This reaction is more reactive and can be exothermic compared to the dissolution of salt in water.
Why do we store sodium metal in kerosene oil not in water?
Sodium metal reacts violently with water, producing hydrogen gas and heat, which can lead to ignition or explosion. Storing sodium in kerosene prevents it from coming into contact with water, reducing the risk of an uncontrollable reaction. Kerosene also forms a protective layer around the sodium, preventing it from reacting with air.
Why do sodium kept immersed in kerosene oil do not burn?
Sodium reacts violently with water, releasing hydrogen gas and forming sodium hydroxide. When sodium is kept immersed in kerosene oil, it is isolated from water, preventing the reaction from occurring. Kerosene oil acts as a barrier to keep oxygen away from the sodium, further preventing combustion.
Is vinegar soluble in kerosene?
No, vinegar is not soluble in kerosene because they are chemically different substances. Vinegar is mostly composed of water and acetic acid, while kerosene is a hydrocarbon mixture. Since water and oil-based substances like kerosene do not mix, vinegar will not dissolve in kerosene.
