The ______is the number in ______of the element or ______. It indicates how (76) many of that ______are part of the reaction. If ______number is written, then the (line 77) 1 is a given (we wouldn’t write the ______if it was not there).
(78) The subscript is ______and slightly below the ______. It indicates how many (79) ______of that element are in the molecule. If no ______is written, then the 1 is a (80) given.
The blank in line 76: coefficient
The blanks in line 77: subscript
The blanks in line 78: small
The blanks in line 79: atoms
The blank in line 80: given
The [78] subscript is [77]small and slightly below the [79]element. It indicates how many [79]atoms of that element are in the molecule. If no [80]subscript is written, then the 1 is a given.
The missing word in the first blank is "coefficient," and it indicates the number of molecules or atoms of the element or compound involved in the reaction.
To find the coefficient, you need to balance the chemical equation. Balancing involves adjusting the number of molecules or atoms on each side of the equation to ensure the conservation of mass. You can achieve balance by adjusting the coefficients.
In line 76, the missing word is "element." The coefficient indicates how many of that element are part of the reaction.
If no coefficient is written, it implies that the coefficient is 1. For example, if the chemical equation is "H2 + O2 → H2O," it means that one molecule of oxygen reacts with two molecules of hydrogen to produce two molecules of water.
In line 77, the phrase "1 is a given" means that the coefficient for that particular element or compound is understood to be 1. Therefore, it is not written explicitly.
Moving on to line 78, the missing word is "subscript." The subscript is a number written slightly below and to the right of an element's or compound's symbol. It indicates the number of atoms of that element in a molecule.
To find the subscript, you need to examine the molecular formula of the compound. For example, in H2O, the subscript "2" indicates that there are two hydrogen atoms in each molecule of water.
If no subscript is written, it implies that the subscript is also 1. For example, in the molecular formula CH4, the subscript of 1 is implied for carbon.
In line 79, the missing word is "atoms." The subscript indicates how many atoms of that element are in the molecule.
If no subscript is written, it means there is only one atom of that element in the molecule.
In line 80, the phrase "1 is a given" means that the subscript for that particular element is understood to be 1. Therefore, it is not written explicitly.
