Choose the 3 correct statements. explain
a
There are 2 molecules of oxygen in the above equation. Each molecule of oxygen has three oxygen atoms.
b
There are 3 molecules of oxygen in the above equation. Each molecule of oxygen has two oxygen atoms.
c
The 3 in 3O2 is a coefficient.
d
The 2 in 3O2 is a coefficient.
e
The 3 in 3O2 is a subscript.
f
The 2 in 3O2 is a subscript.
The three correct statements are:
1) a) There are 2 molecules of oxygen in the above equation. Each molecule of oxygen has three oxygen atoms.
This statement correctly explains that there are two oxygen molecules in the equation and each oxygen molecule consists of three oxygen atoms.
2) c) The 3 in 3O2 is a coefficient.
This statement correctly identifies the number 3 as a coefficient, which is a number that appears in front of a molecule or atom to represent the number of that molecule or atom present in the equation.
3) f) The 2 in 3O2 is a subscript.
This statement correctly describes the number 2 as a subscript, which is a small number written below and to the right of a chemical symbol to indicate the number of atoms or elements present in a compound or molecule.
I do not see the equation but in my world an O2 molecule has TWO O atoms
"......... O2 .......... "
1) a) There are 2 molecules of oxygen in the above equation. " ???? Each molecule of oxygen has three oxygen atoms. ????? "
This statement correctly explains that there are two oxygen molecules in the equation and each oxygen molecule consists of "
three .... " ??? oxygen atoms.
I apologize for the confusion. You are correct, each molecule of oxygen (O2) contains two oxygen atoms, not three. Therefore, statement a) is incorrect.
To clarify, the correct statements would be:
1) b) There are 3 molecules of oxygen in the above equation. Each molecule of oxygen has two oxygen atoms.
This statement accurately describes that there are three oxygen molecules (O2) in the equation, and each oxygen molecule contains two oxygen atoms.
2) c) The 3 in 3O2 is a coefficient.
This statement correctly identifies the number 3 as a coefficient, which represents the number of oxygen molecules (O2) in the equation.
3) f) The 2 in 3O2 is a subscript.
This statement accurately describes the number 2 as a subscript, which indicates the number of oxygen atoms within each oxygen molecule.
