How do you balance chemical equations in chemistry?
Summary
- A chemical equation represents the changes that occur during a chemical reaction.
- Coefficients are used to balance chemical equations.
- To balance a chemical equation, place coefficients as needed in front of the symbols or formulas so the same number of each type of atom occurs in both reactants and products.
What are the 3 rules for balancing equations?
Summary
- To be useful, chemical equations must always be balanced. Balanced chemical equations have the same number and type of each atom on both sides of the equation.
- The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions.
What is balanced equation of photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
How do you balance chemical equations ABC method?
Algebraic method for balancing chemical equations
- Write a different letter coefficient in front of each compound in the equation.
- Write algebraic expressions or rules for each element that equate its atoms on the LHS and RHS.
How do you balance chemical equations examples?
Examples of Balancing Chemical Equations
- Example 1. C5H12 + O2 —> CO2 + H2O.
- Example 2. Zn + HCl —> ZnCl2 + H2
- Example 3. Ca(OH)2 + H3PO4 —> Ca3(PO4)2 + H2O.
- Example 4. FeCl3 + NH4OH —> Fe(OH)3 + NH4Cl.
- Example 5. S8 + F2 —> SF6
- Example 6. C2H6 + O2 —> CO2 + H2O.
- Example 7. Al2(CO3)3 + H3PO4 —> AlPO4 + CO2 + H2O.
Why do we need to balance a chemical equation?
A chemical equation should always be balanced because the law of conservation of mass states that matter can neither be created nor destroyed so in a chemical equation the total mass of reactants must be equal to the mass of products formed i.e. the total number of atoms of each element should be equal on both the …
What are the four rules of balancing equations?
Tip: Start by balancing an element that appears in only one reactant and product. Once one element is balanced, proceed to balance another, and another, until all elements are balanced. Balance chemical formulas by placing coefficients in front of them. Do not add subscripts, because this will change the formulas.
What are the rules for balancing equations?
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.
Why is photosynthesis a balanced equation?
Reactions must be balanced, meaning there needs to be same number each atom on the reactant side as there is on the products side. As you can see, there are 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation. This makes the equation balanced.
Is photosynthesis a balanced chemical reaction?
A chemical reaction is said to be balanced, when both sides of the photosynthesis equation (reactants and products) have the same number of molecules for each of the elements. Now, the number of carbon atoms is 6 in both sides. The remaining atoms to be balanced are hydrogen and oxygen.
