It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
C6H13Na + H2O
Sodium Hydroxide does not undergoes chemical change with water. It just becomes dilute or aqueous.
Yes, it's an exothermic reaction, which means that energy is being released, thus it is a chemical reaction.
The reaction is NaOH +HCl = NaCl +H2O Both sodium hydroxide and Hydrochloric are "used up".
Dissolving is not a chemical reaction; any chemical equation.
A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
It is a chemical reaction - a 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.
physical
That is a chemical change. You are seeing a chemical reaction, where the sodium reacts with the water, forming sodium hydroxide and hydrogen gas.
C6H13Na + H2O
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.
You get Iron (III) Hydroxide and Sodium Nitrate. It is a double displacement chemical reaction...
