An unbalanced equation has more reactants than products, or vice versa. Stoichiometry, the science of balancing equations, uses coefficients to balance both sides of the reaction to follow the Conservation of Mass.
Ex: Ca + H2O --> H2 + Ca2O3 This is unbalanced because there is one more calcium atom and two more oxygen atoms produced than there were put in.
2Ca + 3H2O --> 3H2 + Ca2O3 Now the equation is balanced, with the products equivalent to the reactants.
What else can I help you with?
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 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.
How Chemical equations are balanced by changing the subscripts of the molecule true or false?
False. Chemical equations are balanced by changing the coefficients in front of the chemical formulas, not the subscripts within the formulas. The number of atoms of each element must be equal on both sides of the equation to ensure that mass is conserved.
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.
Why is it incorrect to balance chemical equation by changing the subscripts?
Changing subscripts in a chemical formula changes the identity of the compound, which is not allowed when balancing chemical equations. Balancing equations involves adjusting the coefficients in front of the chemical formulas to ensure that the same number of each type of atom is present on both sides of the equation.
Why are coefficients used in chemical equations?
to determine the mole of the atom
What in chemical equations provide mole ratios that can be used as conversion factors?
Coefficients
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.
Are Chemical equations are balanced by changing the subscripts of the molecules?
ABSOLUTELY NOT Change the coefficients on reactant or productt units.

False. Chemical equations are balanced by changing the coefficients in front of the chemical formulas, not the subscripts within the formulas. The number of atoms of each element must be equal on both sides of the equation to ensure that mass is conserved.
What numbers should not be changed to balance the equations?
Coefficients in front of chemical formulas should not be changed when balancing chemical equations. These coefficients represent the number of each molecule or atom involved in the reaction and changing them would change the stoichiometry of the reaction. Only the subscripts within chemical formulas should be adjusted to balance the equation.
What can be adjusted to balance chemical equations?
Coefficients can be adjusted in front of the chemical formulas to balance chemical equations. Changing coefficients will ensure that the number of atoms of each element is equal on both sides of the equation. Subscripts within chemical formulas should not be changed to balance equations.
Are chemical equations balanced by changing the subscripts of the molecules?
No - they are usually balanced by changing the numbers before the molecules.
How does the method for solving equations with fractional or decimal coefficients and constants compare with the method for solving equations with integer coefficients and constants?
The method is the same.
