How does a subscript in a chemical formula affect balancing chemical equation?
How does a subscript affect the element just before it?
When balancing a chemical equation can you adjust the script in a formula?
No. Never change the subscripts because then you are changing the formula of the substance to something else. You can only change the amount of a substance by adding a coefficient in front of the formula. If there is no coefficient, it is understood to be 1.
If you rewrite the following word equation as a balanced chemical equation what will the coefficient and symbol for fluorine be nitrogen trifluoride nitrogen plus fluorine?
2NF3 --> N2 + 3F2
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.

What is ment by the term coefficient in relation to a chemical reaction?
A coefficient is a number written in front of a chemical formula when balancing a chemical equation. The coefficient can represent the number of atoms, molecules, formula units, or moles of the substance.
A number placed in front of a chemical formula in a chemical equation is called?
In a chemical Equation ,The reactants are on the left side of a chemical equation and the products are on the right side.The number in front of a chemical formula in a chemical equation is called atoms. They should be a balancing number on both the sides.
When balancing equations should you adjust the subscripts or the coefficients?
Subscripts state how many atoms and Coefficients state how many molecules there are. So when balancing an equation you always adjust the coefficients. When this equation is balanced, what is the coefficient for Ni(NOËÄ)ËÄ? 4
How does a subscript in a chemical formula affect balancing chemical equation?
How does a subscript affect the element just before it?
What do you add when balancing a chemical equation?
You add or change the coefficient, never the subscript or it becomes a completely different molecule.*cough 8th grade science*
When the equation for the complete combustion of one mole of C3H7OH is blanced the coefficient for oxygen is?
The balanced equation for the complete combustion reaction is 2 C3H7OH + 9 O2 -> 6 CO2 + 4 H2O; therefore, the coefficient for oxygen is 9. If fractional coefficients are allowed, the equation can be written with only one mole of C3H7OH; in that instance the coefficient for oxygen would be 9/2.
What is the differences between subscripts and coefficients?
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
