What do the prefixes in a covalent compound name tell when writing the chemical formula?
it tells you the number of atoms of each element
What does a chemical formula of a substance tell us?
It tells what elements are present in a molecule and how many atoms of each element are present.
What tells how many atoms of an element are contained in 1 molecules of a substance?
A molecular formula for the substance. The number of atoms of each element present is given by a subscript immediately after the chemical symbol for the element in the molecular formula, with a subscript of "1" being presumed when no subscript is actually written in the formula.
What do subscripts tell you about a compound?
This is farely simple. The subscripts just tell you how many atoms of an element are in the compund. Like this: H20 - Water has 2 hydrogen atoms and 1 oxygen atom CO2 - Carbon Dioxide has 1 carbon atom and 2 oxygen atoms. hence the name carbon di(which means 2)oxide(oxygen). The numbers succeeding elements indicate the number of atoms of that particular element in the compound. For example, in H20, there are two hydrogen atoms and one oxygen atom. In H2SO4, there ar two Hydrogen atoms, one Sulfur atom and four Oxygen atoms.
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
Tell you the number of atoms of each element?
Subscripts :)
What does a subscript tell you?
It tells you how many atoms of an element there are in a molocule.
How many atoms of each kind of element are there in a molecule of carbon dioxide?
1 Carbon atom and 2 Oxygen atoms. The formula is CO2, which means that there are one atom of carbon and two atoms of oxygen in one molecule. The subscripts tell you the numbers of each element. No number is understood to be one.
How many of each kind of element are there in a molecule of carbon dioxide?
1 Carbon atom and 2 Oxygen atoms. The formula is CO2, which means that there are one atom of carbon and two atoms of oxygen in one molecule. The subscripts tell you the numbers of each element. No number is understood to be one.
Does a chemical formula tell you how many atoms of an element are in a unit of a compound?
yes it does
What three things does a chemical formula tell you?
The type and the number of atoms of each element present.
How can you tell that a substance is a compound by looking at it formula?
the formula tells youwhich elements make up a compound as well as how many atoms of each element are present.
How can you tell a substance is a compound by looking at its' formula?
the formula tells youwhich elements make up a compound as well as how many atoms of each element are present.
What information do prefixes in the name of a binary molecular compound tell you about the composition of the compound?
The number of atoms in each element .
What do the prefixes in a covalent compound name tell when writing the chemical formula?
it tells you the number of atoms of each element
Do superscript numbers in chemical formulas tell how many atoms of each element are found in a unit of compound?
No. The function described in the question is performed by subscript, not superscript, numbers.
What does a chemical compound formula tell you?
It tells what elements are present in a molecule and how many atoms of each element are present.
