How can I tell if a chemical reaction is balanced or not balanced?
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
How many oxygen atoms are in the reactant aluminum phosphate in the balanced reaction below?
The reactant aluminum phosphate has a chemical formula AlPO4. There are 4 oxygen atoms in one molecule of aluminum phosphate.
Why is the following equation invalid Al 2O2 --- Al2O3?
Because the numbers of aluminum and oxygen atoms are not the same on both sides of the equation, so the equation is not balanced. In order to be balanced, the numbers of atoms of each element must be the same on both sides of the equation. The correct equation is 4Al + 3O2 --> 2Al2O3. This gives 4 aluminum atoms and 6 oxygen atoms on both sides of the equation, so it is balanced.
How many aluminum atoms would there be on each side of the balanced equation?
To determine the number of aluminum atoms on each side of a balanced equation, you would need to examine the coefficients of the aluminum-containing compounds in the equation. Then, multiply the coefficient by the number of aluminum atoms in each compound. For example, in the equation 2Al + 3CuO → Al2O3 + 3Cu, there are 2 aluminum atoms on each side.
Why is Oxygen not a polar molecule?
A molecule is polar if there is a difference in electronegativity between two atoms that are bonded together. Since there is no difference in electronegativity between two oxygen atoms, O2 is nonpolar.
How are oxygen atoms balanced for red ox equations in acidic solutions?
H2O and H+ are used to balance the oxygen atoms
How are oxygen atoms balanced for redox equations in basic solutions?
H2O and OH- are added to balance the oxygen atoms.
How can one balance equations in acidic solutions effectively?
To balance equations in acidic solutions effectively, follow these steps: Write down the unbalanced chemical equation. Balance the atoms of each element except hydrogen and oxygen. Balance the oxygen atoms by adding water molecules. Balance the hydrogen atoms by adding H ions. Balance the charge by adding electrons. Make sure the number of atoms on both sides of the equation is equal. Check that the equation is balanced in terms of mass and charge. By following these steps, you can effectively balance equations in acidic solutions.
What are some equations that are not balancing?
all equations balance as the theory of conservation of mass states that no mass should be lost, so all equations should balance
Properly balanced equations are necessary for what?
Properly balanced equations are necessary in chemistry to accurately represent the conservation of mass and atoms in a chemical reaction. Balanced equations ensure that all reactants are accounted for and that the number of atoms remain the same on both sides of the reaction.
in balanced chemical equations each side of the equation has the same number of?
Atoms
What is the formula for chemical equations is balanced?
The number of reactants atoms must be equal to the number of products atoms.
Equations show each side is equal as far as the number of atoms and molecules?
In a balanced chemical equation, the number of atoms of each element on both the reactant and product sides are equal, ensuring the law of conservation of mass is satisfied. This balance signifies that no atoms are created or destroyed during a chemical reaction, but instead rearranged.
How many oxygen atoms are in the final product of the balanced reaction 3K2MnO4 2Al 6K Al23?
There are a total of 16 oxygen atoms in the final product of the balanced reaction.
Why are chemical equations always balanced?
Chemical equations are always balanced to satisfy the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing equations ensures that the number of atoms of each element on the reactant side is equal to the number of atoms of the same element on the product side.
What do subscripts in chemical equations tell about the equation?
The subscript in the equation tells you how many atoms of that element there are in the reaction. For example: H20 --> H2 + O2 Before the reaction there are 2 hydrogen atoms and 1 oxygen (the subscript 1 isn't shown). After the reaction there are 2 hydrogen atoms and 2 oxygen atoms. Keep in mind that this is a skeleton equation and isn't balanced yet.
What do balanced and unbalanced chemical equations share in common?
Both balanced and unbalanced chemical equations represent the chemical reactions that take place between reactants to form products. The key difference is that balanced equations have an equal number of atoms of each element on both sides, while unbalanced equations do not.
