Trial and error
1. write the correct formulas for each reactant and product.
2. compare numbers of each kind of element on product vs reactant side. multiply using coefficients to get the same number of each type of atom on both sides.
3. usually leave oxygen for the last element to balance.
After step 1 DO NOT change subscripts, only change coefficients.
first write the unbalanced eqn ,
then count the num of atoms for each element on both sides
if they are not the same,try putting difrnt numbers b4 the atom or molecule until u find zem z same
Also called haber's process to manufacture Ammonia- N2 + 3H2---> 2NH3 + 22400 Kcal energy
HCl + NaOH = H2O + NaCl is already balanced.
The process is not named !!
the haber process the haber process the equation is N2 + 3H2 <--> 2NH3 the haber process! its easy, the equation is N2 + 3H2 <--> 2NH3
There is no chemical equation for argon. A chemical equation describes a process, not an element or compound. Argon does have a chemical symbol, which is Ar.
Checking of the coefficients.
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.
It's called balancing the equation. You did it so that both the reactants and the products have the same amount of the substances.
The overall equation is: CaCO3(s) + 2NaCl (aq) Na2CO3(aq) + CaCl2(aq),
KCl is the chemical formula unit of potassium chloride not a chemical equation.
Evaporation is not a chemical change and so there is no chemical equation.
Combustion reaction equations balance the same way that any other chemical equation does. Every atom that appears on the left side of the equation must also appear on the right side of the equation. No atoms are created or destroyed in the process of a chemical reaction.
Nitrogen balance is not important in the process of building muscle, but testing for nitrogen can help determine whether protein consumption is optimal.

The answer depends on what information you are given - and in what form. If the equation of the curve is given in polar coordinates or in parametric form, the process is quite different to that required when given the Cartesian equation.
