4) double check balance
EXAMPLES:
H2 + O2 --> H2O
"which equals"
2H2 + O2 --> 2H2O
HNO3 + Mg(OH)2 --> Mg(NO3)2 + H2O
"which equals"
2HNO3 + Mg(OH)2 --> Mg(NO3)2 + 2H2O

∙ 13y agoA chemical equation is basically putting compounds, elements, or mixtures together to form something new. When this happens it is a "chemical change" because a new solution is being formed. For example:
2H2+02---->2H20
The 2H2 is just multiple hydrogen elements being combined with 2 oxygen elements. The --> is called the 'yield' or acts in the place of an equal sign. On the left of the yield are the reactants, and the reactants are mixed together to form a product which in this case is 2H20.

When balancing a chemical equation what do the reactants need to be balanced with?
When balancing a chemical equation the reactants need to be balanced with the non-reactants. If you don't the formula will be produce negative results and you'll get the wrong answer.
Which is the next logical step in balancing the given equation n2 plus o2-no2?
The next logical step in balancing the equation would be to change the subscript of the nitrogen molecule to a one.
What have you learned after balancing chemical equations?
being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form
Why is it important never to change a subscription in a chemical formula when balancing a chemical equation?
It is important never to change a subscript {note correct spelling} in a chemical formula when balancing a chemical equation, because changing a subscript produces a formula that specifies a chemical substance different from the one in the original equation.
Why do scientists have to make sure chemical equations are balanced?
Balancing a chemical equation establishes what proportions of the reactants are required for complete reaction as well as the proportions of the products of the reaction. Some factors in balancing the equation will also dictate what the products ARE. For example - when balancing the equation for a combustion reaction, the presence of nitrogen in the fuel molecule will yield certain products while it's absence will exclude certain products. Likewise, when performing electrochemical reaction balances, balancing the electrochemistry will dictate the products of the reaction.
Do you have to choose coefficients that will balance the equation in balancing an equation?
If your goal is to balance the equation, then yes, you have to chose the coefficients.
Where can you compare balancing chemical equation in real life?
We can compare balancing chemical equation to a mother and her children. She should be fair in giving the things that her children want. She should be equal. :)

Describle two reasons for balancing chemical equation?
what is the chemical equation of nitrogen + oxygen= nitric oxide
Balancing a chemical equation is a example of?
An example of a balanced chemical equation is: NaOH + HCl = NaCl + H2O
What is a reaction in a balancing equation?
When an equation is balanced, the rate of the forward reaction equals the rate of the reverse reaction.
Why do you never use fractions when balancing an equation?
It is customary to use integers.
What is the final step in the process of balancing a chemical equation?
Checking of the coefficients.
When balancing a chemical equation what is allowed to adjust?
Coefficients of molecules are adjusted.
What four guidelines are seful in balancing an equation?
1.) Identify the names of the reactants and the product, and write a word equation. 2.) Write a formula equation by substituting correct formulas for the names of the reactants and the products. 3.) Balancing the formula equation according to the law of conservation of mass. 4.) Count atoms to be sure that the equation is balanced.
