Which liquid floats on top water or kerosene?
When water and kerosene are mixed kerosene will float on top.
Is sodium and potassium react violently with water a chemical change?
Sodium and potassium reacting violently with water is a chemical reaction, causing a chemical change.
Give two examples of how water could be dangerous in the laboratory?
1. If mixed with a chemical that reacts violently with water 2. If used to put out an electric fire
Which among kerosene and glycerin is miscible in water?
Kerosine forms a layer when mixed with water because it is lighter than water While glycerene does not form a layer
Why sodium metal is stored in kerosene?
Sodium is extremely reactive. It oxidizes rapidly in air and reacts violently with water. The kerosene prevents the sodium from coming in contact with air, water, or other substances that might oxidize it.
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!

Metals react with water violently Is this a physical or a chemical property?
it is a chemical property
Why sodium metal is stored in kerosene?
Sodium is extremely reactive. It oxidizes rapidly in air and reacts violently with water. The kerosene prevents the sodium from coming in contact with air, water, or other substances that might oxidize it.
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 but whenwater is mixed with sodium, the sodium reacts violently with water.
What are the chemical properties of radium?
Ra is the chemical name. Radium reacts violently with water.
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.
Why kerosene oil is not dissolved in water?
kerosene does not dissolve in water because it is a non polar liquid while water is polar so due to different nature they are insoluble. kerosene due to less density floats over water surface.
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.
