Question

2 multiple choice 1 point which change is allowed when balancing a chemical equation? removing products from the equation adding new elements to the reaction changing subscripts in a chemical formula changing coefficients in front of formulas

Explanation:

Balancing chemical equations requires the number of each type of atom to be equal on both reactant and product sides, while keeping the chemical identities of substances intact. Removing products, adding new elements, or changing subscripts alters the actual reaction or the identity of compounds, which is not allowed. Only adjusting coefficients (whole numbers in front of formulas) changes the quantity of each substance without modifying their chemical makeup, which is the correct method for balancing.

Answer:

Changing coefficients in front of formulas
