Do sodium hydroxide dissolve fat grease and hair in a drain and is it a physical change or chemical change?
It is a chemical change.
Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
When copper sulfate mixed with sodium hydroxide is a form of physical change or chemical change?
Chemical change (which results in physical change).
Is sodium hydroxide dissolve in water a chemical change?
Yes, it's an exothermic reaction, which means that energy is being released, thus it is a chemical reaction.
Is mixing iron iii chloride and sodium hydroxide a chemical or physical change?
It's a chemical change.

When placed in H2O a sodium pellet catches on fire as hydrogen gas is liberated and sodium hydroxide forms chemical or physical change?
It is a Chemical change
Why is sodium hydroxide dissolving in water is a physical change?
Because the molecule of NaOH can be recovered unchanged from the solution.
When sodium is put into waterit react forming sodium hydroxide and hydrogen is this physical change or chemical change?
That's most definitely a chemical change, because new forms of matter are produced. Before the reaction, you had pure sodium and water. After the reaction (which is very explosive by the way), you have sodium hydroxide and hydrogen gas.
Is hydrchloric acid reacting with sodium hydroxide to produce a salt water and heat a physical change or a chemical change?
It is a chemical reaction - a chemical change.
When sodium reacts with water is it a chemical or a physical change?
It is a chemical reaction for not only has the state changed of NaOH, but the identity of the substances have also changed.NaOH + H2O --> Na+ + OH-The "H2O" is not a reactant. It's actually supposed to go over the arrow. Sorry.Nonetheless, the dissolution of NaOH will increase the Hydroxide concentration, thus making it more basic. It will not change the identity of H2O.
Are compounds created through physical changes?
No, only through chemical reactions. Physical changes never change the chemical makeup of something. For example, water tuning in to ice is a physical change. Ice and water both have the chemical symbol H20. On the other hand, a sodium - water reaction forms Sodium Hydroxide and Hydrogen. The compound, hydroxide, is formed.
