NaCl itself is not a change. If you mean the formation of it from sodium ad chlorine, however, it is a chemical change.
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.
a chamical change is when something like your butt explodes into many pieces and you can't glue it back. it is also when you can't poo for seventeen years. thank you come again, no refunds , no checks. we will give free advertisement. must be 18 or older to call. now goodbye
The balanced equation for the reaction between sodium (Na) and chlorine (Cl2) to form sodium chloride (NaCl) is 2Na + Cl2 -> 2NaCl. This equation is balanced because it has an equal number of each type of atom on both sides of the reaction arrow.
H2SO4+2NaCl=2HCl+Na2SO4
This is a single displacement reaction, where zinc (Zn) replaces sodium (Na) in sodium chloride (NaCl) to form zinc chloride (ZnCl2) and sodium (Na) metal. The reaction is also known as a displacement or substitution reaction.
It is a chemical change.2NaCl --> 2Na + Cl2
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).
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.
The balanced chemical equation for the reaction between sodium carbonate (Na2CO3) and hydrochloric acid (HCl) is: Na2CO3 + 2HCl → 2NaCl + H2O + CO2
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).
By this, I assume you mean, the chemical reaction. If this is the case, the answer is 2I +2NaCl
You bet it is. Na2CO3 + 2HCl ==> 2NaCl + H2O + CO2
NaCO3 + CaCl2 --> 2NaCl + CaCO3 (s) In the above reaction, calcium carbonate is precipitated as a solid from the aqueous solution.
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.
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.
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).
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)
