What do the subscript numbers represent in a chemical formula?
They tell you how often an atom - or a group of atoms - are repeated.
What doese a coefficient tell you?
In chemistry, a coefficient in front of a chemical formula tells you how many moles you have. When balancing a chemical equation, the law of conservation of matter must be upheld. To do this, you add coefficients as needed, and these coefficients represent mole ratios of either reactants or products.
In chemistry what is the meaning of subscript?
A subscript looks like this Subscripts are numbers used to tell you how many atoms of an element are present in the equation; for instance: * water H20 has 2 atoms of hydrogen and one of oxygen * glucose C6H12O6 has 6 atoms of carbon, 12 of hydrogen, and 6 of oxygen The large numbers put in front of an equation, either to balance it, or simply to tell you how many molecules there are, is called a coefficient; e.g. in 2H2O , the first '2' is the coefficient, & means that all the atoms following it have to be multiplied by that number - so in 2H2O there are 4 atoms of H, and 2 atoms of 0
What does a chemical equation tell you that your observations do not?
A chemical equation tells you the reactants and the products, and also the ratios of each. The ratios can refer to numbers of atoms and molecules or numbers of moles of each reactant and product.
What does the subscript in a formula tell you?
number of each atom
What do the sub scripts in a chemical equation tell about the equation?
The subscript denotes how much of that atom is in the molecule.
What is the purpose of a subscript in a chemical equation?
the purpose of a subscript is to tell how many atoms of that chemical is used in the formulaThe number of atoms of the same element in the molecule ~APEX
What do subscripts in chemical equations tell about the equation?
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.
In the chemical formula for magnesium chloride what is the number 2 called and what does it tell you?
subscript
What do the subscript numbers represent in a chemical formula?
They tell you how often an atom - or a group of atoms - are repeated.
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
What type of number after a chemical symbol tell how many atoms of that element are in a single molecules?
That would be subscript.
What does 3 types of subscript tell you?
- the atomic number of a chemical element or- the number of a type of an atom in a molecule or- indices for physical/chemical parameters
What do a subscript in a chemical tell you?
The subscript to the right of an element tells you how many atoms of that particular element are in a molecule. For example, in the water molecule H2O, there are two hydrogen atoms and one oxygen atom.
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.
What does coefficent tell you?
the degree of correlation between two sets of data
What does a coefficent tell you?
the degree of correlation between two sets of data
