What tells the ratio of atoms?
The ratio of atoms is determined by the chemical formula of a compound. This formula indicates the type and number of atoms present in a molecule. The subscripts in a chemical formula provide the ratio of each type of atom in the compound.
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.
What script number tells of the preceding element in the compound?
The subscript number after the preceding element in a compound tells how many atoms of that element are in a molecule or formula unit of the compound. For example, the molecular formula for water, H2O indicates that there are 2 atoms of hydrogen and 1 atom of oxygen in one molecule of water. The formula unit for the ionic compound calcium chloride, CaCl2, indicates that there are 1 calcium ion and 2 chloride ions in a formula unit of calcium chloride.
What is importance of naming chemical formula?
A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. It contains the symbols of the atoms of the elements present in the compound as well as how many there are for each element in the form of subscripts
What does C3H8 tell about a molecule of propane?
The formula tells how many atoms of which elements are found in a molecule of propane. It indicates that there are 3 atoms of carbon and 8 atoms of hydrogen in a molecule of propane.
What type of number after a chemical symbol tells how many atoms are in a single molecule?
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
What type of number after a chemical symbols tells how many atoms of that element are in single molecules?
The subscript number after a chemical symbol indicates how many atoms of that element are present in a single molecule of the compound.
What does a subscript tell us about an element in a compound?
In a molecular formula, the subscript tells us the number of atoms of the element that are present in one molecule of the compound. For instance,H2O tells us that there are two hydrogen and one oxygen atom per molecule of water. As for ionic compounds, it tells us the number of atoms present in one formula unit of the compound.
What type of number after a chemical symbol tells how many atoms of that elements in a single molecule?
The number after a chemical symbol in a chemical formula represents the number of atoms of that element in a single molecule. This number is called a subscript, and it indicates the ratio of atoms in the compound.
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 the ratio of atoms?
The ratio of atoms is determined by the chemical formula of a compound. This formula indicates the type and number of atoms present in a molecule. The subscripts in a chemical formula provide the ratio of each type of atom in the compound.
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.
What is the smallest piece of matter a compound can be broken into and still have the same properties?
The smallest piece of matter a compound can be broken into and still have the same properties is a molecule. When a compound is broken down into individual molecules, the chemical properties of the compound remain unchanged because the molecules contain the same types and numbers of atoms that give the compound its characteristic properties.
What does the subscript number stand for?
The number in the subscript of a chemical formula tells the number of that atom in a molecule. For example, in H2O, the 2 tells you there are 2 hydrogen atoms in the water molecule. in C3H8, there are 3 carbon atoms and 8 hydrogen atoms as reflected by the 3 and 8 in the formula respectively.
In the chemical formula CO2 t6he subscript 2 shows which of the following..?
The subscript 2 shows the number of oxygen atoms in each molecule of the compound, carbon dioxide.
What a compound formula tells about compound'?
It tells what elements are in a compound and the number of each type of atom in each molecule/formula unit.
What two things does a chemical formula tell us about a compound?
the actual number of atoms in a molecule
