What do the subscript and coefficent in a chemical equation tell us?
The subscript in a chemical equation tells us the ratio of atoms of each element present in a compound. The coefficient tells us the number of molecules or formula units involved in the reaction.
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 is the name for the 2 in front of 2H2O?
The number 2 IN FRONT is called a coefficient, and it tells you that there are two water molecules.The number BETWEEN the "H" and the "O" tells you that in one single molecule of water, it is made of 2 atoms of hydrogen, and 1 atom of oxygen.For example, if hydrogen gas (H2) is combined oxygen (O2), water (H2O) is formed. Because the formula is H2, two little "2" tells us that hydrogen gas is composed of 2 atoms of hydrogen. Same with oxygen -- O2 is made of two atoms of oxygen. The balanced equation for the reaction to form water is: 2H2 + O2 ---> 2H2OWhat the numbers in front of the molecules mean is that 2 molecules of hydrogen combine with one molecule of oxygen to form 2 molecules of water.See the Related Questions about balanced equations and stoichiometry for more about how coefficients are used and what they tell us about a reaction.
What is the chemical name for nH2O?
The meaning of nH2O is a n (unknown) number of crystallization water molecules.
The atomic number tells you the number?
The atomic number tells you the number of protons in the nucleus of an atom of the associated element.
What information does the coefficient provide in a chemical reaction?
It tells you the number of molecules or number of moles of each substance.
What type of number after a chemical symbol tells how many atoms of that element are in a single molecules?
That would be subscript.
What is the number placed in front of a chemical formula that tells how many atoms or molecules there are in the formula?
That is called a coefficient in a chemical equation. It indicates the number of molecules or units of a substance involved in a reaction.
The prefix used in a chemical name tells what?
the prefix can provide information towards the geometric shape of the chemical (how molecules are laid out).
The number in front of a chemical formula that tells how many molecules or atoms of each reactant take part in a reaction called?
subscript
What is the name number tells you the amount of protons and neutrons in an element?
Number of protons + Number of neutrons = Mass number(number of nucleons)
What is the name for the number in a fraction that tells how many equal parts are shaded?
numerator
What does the name of a hydrate indicate about its cpmosition?
The number of water molecules it contains.
What is avogandro's number?
Avogadro's number, approximately 6 x 1023, tells us how many atoms molecules are in a mol. For example, it tells us approximately how many hydrogen atoms in a gram of hydrogen, how many carbon atoms in 12 grams, etc.
What is the name of a number in front of a chemical formula in an equation called?
This is the number of molecules or atoms involved in the reaction.
