sulphur can not be mixed with water.
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
Water its a chemicl compound Other possible odd ones out are:- Neon is a gas at normal temp and pressure none of the others are Water is a liquid at normal temp and pressure, none of the others are
its a chemical change which forms suphurous acid (H2SO3) and nitric acid (HNO3)

Definitely chemical. I can tell because when I do it, it lets off a sulfur smell, indicating that hydrogen sulfide has been released. I've run the same test with other acids and come up with similar results, only the residue left behind after evaporation is different. The hydrogen must be bonding with the sulfur inside the chalk and creating that strong smell (more noticeable if you use a odorless acid). Did you know that pure elemental sulfur is odorless? The true chemical you smell is hydrogen sulfide, not plain sulfur.
Boiling is a physical phenomenon, a change of phase.
is water and oil a physical change or chemical change.
No, it is a physical change. The water and gasoline retain their chemical and physical properties.
It is a physical change.
Freezing water is an example of a physical change because the material contents of the water has not changed.
water condensing is a physical change.
Condensation of water is a physical change.
