To balance a chemical reaction, you adjust the coefficients in front of each compound to ensure that the number of atoms for each element is the same on both the reactant and product sides. Start by balancing elements that appear in only one reactant and one product before moving on to more complex molecules. Remember that you cannot change subscripts to balance a chemical equation.

∙ 9y agoTo illustrate I will use the example of the oxidation of Cu^+ to Cu^2+ with permanganate.
Write each half equation out (if they have not been provided for you). Oxygen atoms require the addition of 2 H^+ ions each, to produce water. You need to know what each species is being oxidised or reduced to in order to do this.
In this example permanganate is being reduced to Mn^2+
Cu^+ -> Cu^2+ + e^-
MnO4^- + 8H^+ +5e^- -> Mn^2+ + 4H2O
Then work out the ratios of the reactants based on the ratios of electrons (1:5 in this case) and add the equations together. The electrons will cancel out.
MnO4^- +5Cu^+ 8H^+ -> 5Cu^2+ + Mn^2+ + 4H2O

∙ 16y agoI'm not quite sure what you mean by "balance a reaction in acidic solution." The only thing I can think of that you could mean is how do balance a redox reaction in acidic solution.
For specific instructions on how to balance a redox reaction in both acidic and basic solutions, see the Related Questions links to the left.

∙ 14y agoGetting the proportions right between the 2 sides. You have to have the same number of each atom on both sides (law of conversation of matter). 2O2+C4 = 4CO2 You have 4 oxygen atoms, and 4 carbon atoms. When you combine them you get 8 atoms all together. They are the same on both sides. Say you had 2 of the carbon molecules though. 2O2+2C4 = 4CO2 Then the sides wouldn't be equal and you would need to have 4 dioxide molecules on the reactants side and 8 carbon dioxide molecules on the products. 4O2+2C4 = 8CO2 So that both sides would have 16 atoms.

What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
Chains of chemical reactions in living organisms are called?
Metabolic pathways. These pathways involve a series of interconnected chemical reactions that convert molecules into energy or create necessary building blocks for the organism. Each step is catalyzed by specific enzymes to maintain a balance of energy and essential molecules in the organism.
When a battery is used up why is its stored chemical energy used up?
Simply put, such a battery depends on a chemical reaction. Reactions can only take place when there is an inbalance between the chemicals. Once a balance is acheived then no more reactions can take place.
What is the reaction table?
The reaction table, also known as the reaction matrix, is a structured representation of chemical reactions involving reactants and products. It displays how reactants are transformed into products and helps to balance chemical equations. It is commonly used in chemistry to understand and analyze reactions.
What bsre the materials for chemical reactions?
materials used in chemical reactions are reactants
Is metabolism considered the balance of chemical reactions within the organisms body?
metabolisim
The series of chemical reactions that balance the synthesis and release of energy in organisms is known as?
Metabolism.
What is the meaining of chemolibrium?
Chemolibrium refers to a state of chemical balance or equilibrium within a system, where the rates of forward and reverse chemical reactions are equal. This balance is essential for maintaining stability and ensuring that reactions proceed in both directions at a steady rate.
How do you solve a chemical reactions?
It is necessary to balance the relation between reactants and products. You need to know these compounds, chemical formulas, valences.
What does balance mean in scientific terms?
In scientific terms, balance refers to the state of equilibrium achieved when opposing forces or influences are equal. This can apply to various aspects of science, such as chemical reactions or ecosystem dynamics, where a balance must be maintained for optimal functioning.
Complete and balance the following chemical reactions C5H10OH plus O2?
C5H10OH + 7O2 -> 5CO2 + 6H2O
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
Chains of chemical reactions in living organisms are called?
Metabolic pathways. These pathways involve a series of interconnected chemical reactions that convert molecules into energy or create necessary building blocks for the organism. Each step is catalyzed by specific enzymes to maintain a balance of energy and essential molecules in the organism.
Why is it useful to write chemical equations?
Chemical equations help to visually represent chemical reactions by showing the reactants, products, and their respective amounts. They provide a way to balance reactions, predict products, and calculate quantities of substances involved. Additionally, they allow for easy communication and understanding of chemical processes.
How are chemical reactions abbreviated?
Chemical reactions are abbreviated by their chemical equations.
When a battery is used up why is its stored chemical energy used up?
Simply put, such a battery depends on a chemical reaction. Reactions can only take place when there is an inbalance between the chemicals. Once a balance is acheived then no more reactions can take place.
How enzymes control chemical reactions?
enzymes helps control chemical reactions by the chemical in it called collagen when enzymes enter your body they create a chemical reactions and controls the chemical reactions you get by eating too much acids.
