Answer from: audriexpress

There must be the same number of atoms of each element on both sides of the equation.

Explanation: This is the only way the equations will be balanced. Adding the coefficients to see if they are equal will not guarantee that the equations are balanced becuase coefficients can be turned into subscripts.

Coefficients need to be changed while balancing a chemical reaction beacuse subscript show how the molecule exists in nature

Answer from: dzepeda061

Coefficients

Explanation:

Chemical equations are first written as a skeleton equation, which includes how many atoms each element and compound has. Skeleton equations are not 'balanced' because the number of atoms of each element on the left side (reactants) is not equal to the right side (products).

To balance a chemical equation, you can write coefficients in front of single elements and compounds. The coefficient multiplies with each single element and with each element in the compound.

For example, in this skeleton equation:

H₂ + Cl₂ => HCl

Reactants: Products:

2 hydrogen 1 hydrogen

2 chlorine 1 chlorine

Write the coefficient 2 in the products.

H₂ + Cl₂ => 2HCl

Now both reactant and product sides have 2 chlorine and 2 hydrogen, so the equation is balanced.

Changing a subscript changes the substance represented by the formula

Answer from: SketchWasTaken

Only coefficients can be changed

Answer from: hannahbannana98

Subscripts are the identity of the element (the number of atoms) whereas coefficients are the number of molecules of the element.

If you change the subscript, you change the number of atoms an element has. This changes the entire element since each element in the periodic table have different atomic numbers.

Because of making the equestion to be more stable and form the best compound according to it's reactant.

Answer from: mutesheep

Hey your answer is this- only coefficients can be changed in order to balance a chemical equation. Subscripts are part of the chemical formula for reactants or products and cannot be changed to balance an equation. Changing a subscript changes the substance represented by the formula
