The subscript in the equation tells you how many atoms of that element there are in the reaction. For example:
H20 --> H2 + O2
Before the reaction there are 2 hydrogen atoms and 1 oxygen (the subscript 1 isn't shown). After the reaction there are 2 hydrogen atoms and 2 oxygen atoms.
Keep in mind that this is a skeleton equation and isn't balanced yet.
What else can I help you with?
What do subscripts in a chemical equation tell you?
Subscripts in a chemical equation indicate the ratio of atoms of each element in a compound. They provide information on the number of atoms present in a molecule and help to balance chemical equations by showing the correct stoichiometry of the reaction.
Why cant the subscripts of a chemical equation be changed?
subscripts define the ratio of atoms to atoms, or ions to ions in a compound. they are set by the valence electrons, they only fit in certain ways. why change them other than to make balancing equations easier. balancing equations is not supposed to be too easy, just work harder at it. don't adjust the universe to fit into a simple way to look at things. NERD!
What are codes used in chemical equations telling what atoms are part of the equations?
formulas
Which is chemical equation?
A chemical Equation is a shorthand form of a chemical reaction. chemists use it to help them tell the substances that are present such as reactants, products, or proportions.Some equations also tell the physical state of a substance.
In a chemical formula what do subscripts mean?
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
What can chemical equations tell you about a chemical reactions?
Chemical equations describe the products and reactants in a chemical reaction.
What formulas arrow and plus signs in a chemical equation tell you?
Chemicals equations use chemical formulas and other symbols instead of words to summarize a reaction.
What do the formula of a chemical equation tell you?
The formula of a chemical equation tells you the type and number of atoms or molecules involved in a chemical reaction. It helps to balance the equation to ensure that mass is conserved and the reaction follows the law of conservation of mass.
Does a chemical formula describes a chemical reaction?
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
What are three things that chemical equations can tell you about a chemical reaction?
A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
How can you tell that an equation has the same solution as the original equation?
If the two equations are linear transformations of one another they have the same solution.
