First off, it is going to be NaCl, not NaCl2 and Cl2, not Cl. Secondly, the balanced equation would be H2 + 2NaCl -> 2NaH + Cl2

Why are coefficient used to balance equations?

Coefficients are used to balance equations because if you change the subscript, than you would change the substance.


What are used to balance chemical equations?

Coefficients are used to balance chemical equations. These numbers are placed in front of the chemical formulas to ensure that the number of atoms on both sides of the equation are equal.


How are coefficients used to balance chemical equations?

Coefficients in front of chemical formulas are used to balance chemical equations by ensuring that the number of each type of atom is the same on both sides of the equation. By adjusting the coefficients, you can keep the law of conservation of mass intact, showing that no atoms are created or destroyed during a chemical reaction.


Where should coefficients be place when balaning a chemical equation?

Coefficients should be placed in front of the chemical formulas in a chemical equation to balance it. They are used to ensure that the number of atoms of each element is the same on both the reactant and product sides of the equation.


How are coefficients used in writing chemical equations?

Coefficients in chemical equations are used to balance the number of atoms of each element on both sides of the equation. They help ensure that the law of conservation of mass is followed, which states that atoms are not created or destroyed in a chemical reaction, but are rearranged. By adjusting coefficients, the equation can accurately represent the reaction taking place.


What is the name for the numbers that appear in the front of the chemical formula in a balanced equation?

The numbers that appear in front of the chemical formulas in a balanced equation are called coefficients. Coefficients are used to balance the equation by ensuring that the number of each type of atom is the same on both sides of the equation.


What do you call the numbers used to balance equations?

The numbers placed immediately before formulas of compounds and/or elements involved in the reaction are called "coefficients" and those placed immediately after element symbols, depressed below the typographical line of the element symbol are called "subscripts". The subscripts show the number of atoms of a particular element in a formula unit of a molecule or other compound.


What coefficients must be used to balance the following decomposition reaction?

To balance a decomposition reaction, ensure that the number of each type of atom is the same on both sides of the equation. For example, if you have the reaction AB -> A + B, you would need to use a coefficient of 1 to balance the reaction. If the reaction is more complex, use trial and error to determine the coefficients needed.


The coefficients from a balanced equation are used to write conversion factors called?

stoichiometric coefficients.


When Number left of formulas for reactants are called?

The numbers left of formulas for reactants in a chemical equation are called coefficients. They indicate the relative number of moles or molecules of each reactant and product involved in the reaction. Coefficients are used to balance chemical equations, ensuring that the law of conservation of mass is upheld.
