Chemical reactions happen on a molecular level
Physical reactions are concerned with a change in state or energy level, so melting is considered a physical reaction since there is no molecular change just a change in state.
No chemical reaction, only a solution containing ions of potassium, sodium and chlorine.
acetic anhydride and sodium chloride will form.
The chemical formula of sodium hydroxide is NaOH. The chemical formula of ammonium chloride is NH4Cl. Any reaction between these substances in water solution.
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?
2NaCl+(NH4)2CO3
This is a chemical reaction, a chemical change.
It is not a chemical reaction.
A strongly exothermic reaction to produce a salt, sodium chloride.
A chemical reaction occur and sodium chloride is the product.
For example the product of the reaction between sodium chloride and silver nitrate is the insoluble silver chloride.
Sodium chloride is dissociated in water: NaCl---------------------Na+ + Cl-
No chemical reaction, only a solution containing ions of potassium, sodium and chlorine.
This is a chemical reaction.
Nacl
acetic anhydride and sodium chloride will form.
No chemical reactions occur because sodium only forms ions like chloride.
