What chemical equation is properly balance?
The reactants must be balanced correctly with reactants.
How do you balance a combustion reaction?
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.
How can you balance a chemical equation using coefficients?
Co-efficients are written in a chemical equation to balance the equation. this is due to the conservation of mass seeing how we can't make substances out of nothing. For Example. NaOH + H2SO4 --> Na2SO4 + H2O As you can see on the left side, there is only one Na (sodium) atom, but on the right hand side we have 2. meaning that an extra sodium atom appeared from no where and this VIOLATES the conservation of mass. so we must balance is 2NaOH+H2SO4 --> Na2SO4 + 2H2O There are 2 Na on both sides There is 1 sulfur (s) on both sides there is 4 H on both sides and 6 oxygen on both sides. Hope this helps :D
What is a balance equation that indicate that it is conserved?
The mass of reactants must be equal to the mass of products.
What must combined to create a chemical equation?
A chemical reaction imply minimum two reactants (chemical compounds), to obtain the final products.

Why is it wrong to change subcripts when balancing chemical equation?
When you are balancing known reactants and known products which is always the case when you are asked to "balance" a chemical equation you must not change the subscripts as that changes the reactants or the products to a different chemical compound.
What particles must have an equal number on both sides of a chemical equation?
Due to the law of conservation of mass and matter, all particles must have an equal number on both sides of a chemical equation. An equal number of atoms of each element involved must be on each side of the equation.
When writing a chemical equation what must be written first?
First write down what you know. Reactants go on the left, followed by an arrow, with products on the right. Balance the equation.
Why should chemical equation be balance?
According to Law of conservation of mass - The mass of matter can neither be created nor be destroyed. So, th no. of mass in reactants and products in chemical eequation should be same. To satisfy this Law chemical equation should be balance.
Why must a chemical equations be balanced?
Matter is conserved in a chemical reaction, meaning nothing "disappears" when compounds react. Accordingly, the number of atoms you start with has to be the number of atoms you end with. Similarly, no element can become another element, so there must be the same number of each kind of atom at the start and at the end. If you don't balance the equation, you cannot use it to calculate yield. When you balance the equation, you are applying the law of 'Conservation of Mass' or as some like to include 'Conservation of Mass and Energy'.
What is the need to balance a chemical formula?
When designing a chemical process in a plant, the accountants need what is called a mass balance. This way the product can be costed and a selling price and profit margin derived. For accurate costing, the number of moles must be known and with molecular weight the amount can be derived. This can only be done with a balanced chemical equation.

How do you solve an unbalanced chemical equation?
You add whole-number coefficients as needed until the number of each type of atom is the same on either side of the arrow.Example: given this unbalanced equation: C3H8 + O2 --> CO2 + H2O, you must add some coefficients in front of those substances to make it balance. The solution is: C3H8 + 5O2 --> 3CO2 + 4H2O. Now you can see there's the same number of carbons, hydrogens, and oxygens on each side. Note - the absence of a coefficient means it's understood to be "1".
Which do you use to balance equations subscrips or coefficients?
Both. you must have the correct subscripts to represent the correct chemical then you only change the coefficients to balance the equation. The product of a coefficient and a subscript tells how many atoms are present.
Why do you need a balanced equation to do stoichiometry?
A chemical equation must respect the law of mass conservation.
How can use the law of conservation of mass to help you balance a chemical equation?
The law of conservation of mass means that the same number of each atom must be present on both sides of the equation, so that the mass of the reactants equals the mass of the products.
