NaCl itself is not a change. If you mean the formation of it from sodium ad chlorine, however, it is a chemical change.

When chlorine gas is separated from sodium chloride gas which change will occur physical or chemical?

It is a chemical change.2NaCl --> 2Na + Cl2


The chemical reaction 2Na plus Cl2 ----- 2NaCl is an example of a?

The chemical reaction 2Na + Cl2 → 2NaCl is an example of a synthesis reaction, where two or more substances combine to form a more complex product. In this reaction, sodium (Na) reacts with chlorine gas (Cl2) to produce sodium chloride (NaCl).


What is the chemical equation that shows the reaction between sodium and chlorine?

The chemical equation for the reaction between sodium and chlorine is: 2Na + Cl2 → 2NaCl. This reaction forms sodium chloride (table salt) in which sodium loses an electron to chlorine to form an ionic compound.


What is the balanced equation for the chemical reaction of sodium carbonate and hydrochloric acid?

The balanced chemical equation for the reaction between sodium carbonate (Na2CO3) and hydrochloric acid (HCl) is: Na2CO3 + 2HCl → 2NaCl + H2O + CO2


What is the chemical equation for Hydrocloric acid and sodium?

The chemical equation for the reaction between hydrochloric acid (HCl) and sodium (Na) is 2HCl + 2Na -> 2NaCl + H2. This reaction produces sodium chloride (NaCl) and hydrogen gas (H2).

Are all changes considered a chemical reaction?

No. There are two main types of changes: physical and chemical.A physical change does not affect the chemical make up of the element/compound/etc. For example, when you heat water up enough it changes from its liquid state, H2O (l), to its gaseous state, H2O (g). However, as you may have noticed, although the state of matter changed (liquid to gas) the chemical formula, H2O, remained the same. Physical changes include change in state, temperature, or shape, among others.A chemical change, or a chemical reaction, changes the chemical makeup of the affected substance. The reaction can occasionally change the state of the matter, but the difference is that the formula of the old substance changes, creating an entirely new substance. This example demonstrates a chemical reaction:2 Na(s) + Cl2(g) → 2NaCl(s)As you can see, the product is entirely different from the two reactants. Chemical changes can be recognized through the use of key identifiers: change in energy, odor, color, or temperature; the formations of precipitates or solids; and/or gas bubbles.


What compound is 2nacl br2?

The compound 2NaCl + Br2 is not a specific compound itself. It represents a chemical reaction where two moles of sodium chloride (NaCl) react with one mole of bromine (Br2). The products of this reaction would be sodium bromide (NaBr) and possibly other byproducts depending on reaction conditions.


Balanced chemical equations of the reaction between sodium carbonate and calcium chloride?

The balanced chemical equation for the reaction between sodium carbonate (Na2CO3) and calcium chloride (CaCl2) is 2Na2CO3 + 3CaCl2 -> CaCO3 + 2NaCl + 2CaCl2. This reaction results in the formation of calcium carbonate (CaCO3), sodium chloride (NaCl), and excess calcium chloride (CaCl2).


What type of reaction is CuCl2 Na2S?

Ionisation in solution is not a chemical reaction. It can be written as one but still it's NOT: only physical change of state ( subscripted between brackets (s) or (aq) ) Na2S(s) --> 2Na+(aq) + S2-(aq)
