The term 2NaCl represents a chemical formula indicating the composition of a compound. In this case, it stands for two sodium (Na) atoms bonding with one chlorine (Cl) atom to form sodium chloride, which is commonly known as table salt. The subscript "2" indicates that there are two sodium atoms for every one chlorine atom in the compound.
I didn't mean it!I mean, seriously what's your problem?You are being so mean.
"bon" mean "good" and partir mean "to leave"
moron mean>?
bisit mean
what does it mean
2NaCl + Ni (for A+)
Sodium chloride
The balanced equation for CaSO4 + 2NaCl is CaCl2 + Na2SO4.
The molecular equation for the reaction between sodium iodide (NaI) and chlorine gas (Cl2) would be: 2NaI + Cl2 -> 2NaCl + I2.
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.
The balanced equation for the reaction between calcium chloride (CaCl2) and sodium oxalate (Na2C2O4) is: CaCl2 + Na2C2O4 → CaC2O4 + 2NaCl
(Don't forget to balance it) The precipitate here has to be 2NaCl, as Ca(CO3)2 technically dissolves.

2NaI + Cl2 → 2NaCl + I2
The net equation for the reaction between MgCl2 and NaOH is: MgCl2 + 2NaOH -> Mg(OH)2 + 2NaCl
2NaCl is a chemical compound composed of two atoms of sodium (Na) and one molecule of chlorine (Cl) covalently bonded. Therefore, it is a chemical compound, not a chemical reaction or physical change.
CaCO3 + 2NaCl ------> CaCl2 + Na2CO3
