The reason why Chemical equations are balanced is because each side of the equation must have the same amount of atoms, it is impossible to, for example, have this side with 3 O and that side with 4 O.
How to check:
Here's a really good and famous example(Guranteed your cehmistry teacher will mention this some day!):
CaO + H2O = Ca(OH)2
Is it balanced?
There's one Ca(Calcium) on one side, same with the other side. (Balanced!)
There's 2 Oxygen on one side, same with the other.(OH)2 Means two Oxygen, two Hydrogen.(Balanced!)
There's 2 Hydrogen on both sides as well(H2).
So the whole thing's balanced!
If it's not balanced, you can't change the numbers, you have to change the number in front. e.g. in the chemical equation of photosynthesis, there's a 6H2O. That means that there is 12 hydrogen and 6 Oxygen, change that "6" at the front to balance stuff. If there's no number at the front, that's the same as "1".
The balanced chemical equation for the reaction of sulfur dioxide with water is: SO2 + H2O → H2SO3
If a chemical equation is not balanced, it violates the Law of Conservation of Mass. This law states that matter cannot be created or destroyed in a chemical reaction, so the number of atoms of each element must be the same on both sides of a balanced chemical equation.
The balanced chemical equation for burning C18H38 in air is: 2C18H38 + 55O2 → 36CO2 + 38H2O
C2H5OH +3O2 gives 2CO2 +3H2O ...it burns with ablue flame in air
the coefficients of a balanced reaction
A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.
The reactant with the smallest coefficient in a balanced chemical equation is considered the limiting reactant because it limits the amount of product that can be formed.
Balanced Chemical equation
Proteins have a very complicate chemical formula but not a "balanced chemical equation".
A balanced chemical equation.
The balanced chemical equation for potassium chloride is 2KCl = 2K + Cl2.
No, the chemical equation is not balanced. The correct balanced equation is 2SO2 + O2 → 2SO3.
The balanced chemical equation for copper sulfate is: CuSO4 + H2O → CuSO4•5H2O
The balanced decomposition chemical equation for hexane (C6H14) is: 2C6H14 → 6C + 7H2
The balanced chemical equation for magnesium burning in oxygen is: 2Mg + O2 -> 2MgO
Equations are oftentimes used to represent chemical reactions. They have to be in the lowest form for it to be considered a balanced equation.
The coefficient of Al in a balanced chemical equation would depend on the specific reaction being considered. It is determined by ensuring that the number of atoms of each element is the same on both sides of the equation.
