No, it is a chemical substance.
The explosion is a violent chemical reaction.
Solubility is considered as a chemical property.
Production of CO2
'Na' is Sodium. The use of 'Na'. comes from the Latin name for sodium , which is 'Nadium' Similarly 'K' is Potassium. The use of 'K'. comes from the Latin name for potassium , which is 'Kalium' NB There are a number of other elements in the Periodic Table, where the symbol does not indicate the modern name.
Basic because when sodium borohydride is placed in water, the sodium ion and the borohydride ion split, borohydride abstracts a proton (in the form of H+) from a water molecule.
It makes salt and water!
Sodium when placed in water explodes.
pure sodium reacts to just about everything... it even explodes when placed in water
Yes, buoyancy is considered a physical property. It is a type of physical property because it is related to the density and weight of the item, which are both physical.
It is a Chemical change
Solubility is considered as a chemical property.
That is a chemical change. You are seeing a chemical reaction, where the sodium reacts with the water, forming sodium hydroxide and hydrogen gas.
Sodium Hydroxide isn't placed in a burette because it is a solid, and burettes hold liquids.
Sodium cations and carbonate anions.
when the property is sold of course.
Sodium sulfate anhydrous can absorb water.
Physical position is where items are placed.
