An equation written may or may not be balanced. It is balanced if the number of elements on both sides of the arrow, that is before and after the reaction, is equal. Sometimes the number of elements is not the same on both sides of the arrow, then we need to balance the equation. This is done in accordance to the law of conservation of mass which states that the mass of a substance does not get destroyed or created due to a chemical reaction.

Are there any synonyms for the words chemical equation?
A chemical equation written in symbols is sometimes called a balance equation, because the numbers of each kind of atom have to balance on both sides. If it's written in words it's called a word equation.
What are two things you cannot do to a subscript in a chemical equation?
1. You cannot change the subscript just to help you balance the equation. You can only balance an equation by using whole-number coefficients written at the beginning of a substance. 2. If no subscript is present, you can't just add one to help you balance the equation for same reason listed above.
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 are large numbers placed to the immediate left of the element's symbols in a chemical equation that are used to balance the chemical equation?
Those are the coefficients, which represent the relative number of moles of each substance involved in the reaction. Balancing the coefficients ensures that the law of conservation of mass is obeyed in the chemical equation. These coefficients are adjusted to ensure that the number of atoms of each element is the same on both sides of the equation.
What is written in front of the formula used to balance chemical equations?
The reactants are written on the left side of the equation, while the products are written on the right side. The equation is balanced by adjusting the coefficients in front of the chemical formulas so that the number of atoms for each element is the same on both sides.
What is the difference between a subscript and coefficiant?
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.

How do you write a balanced equation for the oxidation of sucrose?
how do you write the balance equation of sucrose?
When first learning to balance equations you learned that the number of atoms of each element in the products and reactants must be equivalent What are some additional factors that must be taken into?
Some additional factors to consider when balancing equations include ensuring the charges are balanced, verifying that the chemical formulas are correctly written, incorporating any coefficients needed to balance the equation, and confirming that the reaction obeys the law of conservation of mass.
How does a correctly written chemical equation show that atoms are not lost in a chemical equation?
By having the same numbers of atoms of each kind of element present in the equation in the written numbers (coefficient multiplied by subscript) of each kind of element on both sides of the equation.
How do you balance SiCl4 plus H20 equals H4SiO4 plus HCl?
To balance the equation SiCl4 + 4H2O → H4SiO4 + 4HCl, you first balance the silicon atoms by putting a coefficient of 1 in front of SiCl4 and H4SiO4. Then balance the chlorine atoms by adding a coefficient of 4 in front of HCl. Next, balance the hydrogen atoms by placing a coefficient of 4 in front of H2O. This gives you a balanced equation: SiCl4 + 4H2O → H4SiO4 + 4HCl.
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.
