One thing you cannot do to balance an equation is to change the subscripts of the chemical formulas. Subscripts indicate the number of atoms of each element in a compound, and altering them changes the identity of the substance. Instead, to balance an equation, you can only adjust the coefficients, which represent the number of molecules or moles of each compound involved in the reaction.

What are two things you cannot do to a subscript in a chemical equation?
1. You cannot change the subscript just to help you balance the equation. You can only balance an equation by using whole-number coefficients written at the beginning of a substance. 2. If no subscript is present, you can't just add one to help you balance the equation for same reason listed above.
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
How is the best describes a balance reaction?
The correct answer is: A reaction that has the same number and type of atoms on each side of the equation.
A chemical reaction is balanced by changing?
To balance a chemical equation, you can change the coefficients (number of molecules). Remember: You cannot change the subscripts.When we balance an equation we change the number of atoms on one or both sides of the equation by means of simple mathematical calculation. That is, we change the number of molecules of one or more reactants or products. When the number of atoms of each element is equal on both sides of the equation, and cannot be reduced equally, the balancing process is complete.
Is this balance H2 O2-H2O?
No, the equation H2 O2 - H2O is not balanced. To balance it, you would recognize that one molecule of hydrogen peroxide (H2O2) can decompose into two molecules of water (H2O) and one molecule of oxygen (O2). The balanced equation would be: 2 H2O2 → 2 H2O + O2.

What would you change to balance a chemical equation?
You can balance a chemical equation by adjusting the coefficients of the compounds involved. Start by balancing the atoms that appear in only one reactant and one product, then balance the atoms that appear in more than one compound. Finally, check that the equation is balanced by verifying that the number of each type of atom is the same on both sides of the equation.
How is equality maintained when solving an equation?
Whatever is done on one side of the equation must be repeated on the other side of the equation to maintain balance and equality.
How is the best describes a balance reaction?
The correct answer is: A reaction that has the same number and type of atoms on each side of the equation.
What is one thing that every equation contains?
An "equals" sign. That's why it is an equation, two parts are equal.
What is -190-10r?
-180
What does a balance sheet look like?
One way to describe the balance sheet is a more detailed version of the accounting equation. A= L+E.
What is the coefficent that shows in a chemical equation?
Equations for chemical reactions may require one or more whole-number coefficients in order for the equation to balance. Balancing a chemical equation upholds the law of conservation of mass, which states that matter cannot be created or destroyed. The coefficients represent molar ratios of reactants and products. Performing stoichiometric calculations is largely dependent upon these correct molar proportions.
How do you balance al o2al2o3?
To balance the equation Al + O2 -> Al2O3, first write out the unbalanced equation. Then balance the atoms one at a time, starting with the least common elements. In this case, balance aluminum first by adding a coefficient of 4 in front of Al on the left side. Then balance oxygen by adding a coefficient of 3 in front of O2 on the left side. The balanced equation is 4Al + 3O2 -> 2Al2O3.
How do you balance Na1Cl2?
Your question leads me to believe that you have the following equation: Na + Cl ---> NaCl2 In that case, note there is one Na (sodium) on the left and one on the right, so they are good. There's one chloride on the left but two on the right, so placing a "2" in FRONT of the Cl on the left will balance the equation and look as such: Na + 2Cl ---> NaCl2
In the equation 2 plus 34 what should be done first?
There is only one thing to do in this equation; add 2 to 34
