Barium nitrate, Ba(NO3)2:
Ba - 1 atom
Nitrogen - 2 atoms
Oxygen - 6 atoms
Total - 9 atoms
In the chemical formula Ba3(PO4)2, there are 3 barium (Ba) atoms, 2 phosphorus (P) atoms, and 8 oxygen (O) atoms (since there are 4 oxygen atoms in each phosphate group and there are 2 phosphate groups). Adding these together, the total number of atoms is 3 (Ba) + 2 (P) + 8 (O) = 13 atoms.
Barium hydroxide (Ba(OH)2) has 3 atoms: 1 barium atom (Ba) and 2 hydroxide groups, each consisting of 1 oxygen atom (O) and 1 hydrogen atom (H).
To find the number of atoms in 3Ba(CLO3)2, first determine the composition of one molecule of Ba(CLO3)2. It contains 1 barium (Ba), 2 chlorine (Cl), and 6 oxygen (O) atoms, totaling 9 atoms per molecule. Therefore, in 3Ba(CLO3)2, there are 3 × 9 = 27 atoms.
It has 6 oxygen atoms.
In barium chlorite, Ba(ClO2)2, the oxidation state of barium (Ba) is +2. Each chlorite ion (ClO2-) has a charge of -1. Within the chlorite ion, the oxidation state of oxygen is -2, so for two oxygen atoms, that totals -4. To balance this, the oxidation state of chlorine must be +3. Therefore, the oxidation state of Cl in Ba(ClO2)2 is +3.
The formula unit Ba(NO3)2 contains 6 oxygen atoms. (Multiply the subscript 3 in the nitrate ion by the subscript 2 after the parentheses close.)
There are a total of 6 oxygen atoms in Ba(OH)3)2. Each hydroxide ion (OH-) contains one oxygen atom, and there are 6 hydroxide ions in Ba(OH)3)2.
In the chemical formula Ba3(PO4)2, there are 3 barium (Ba) atoms, 2 phosphorus (P) atoms, and 8 oxygen (O) atoms (since there are 4 oxygen atoms in each phosphate group and there are 2 phosphate groups). Adding these together, the total number of atoms is 3 (Ba) + 2 (P) + 8 (O) = 13 atoms.
Ba(NO3)2 contains a total of 6 oxygen atoms - there are 3 oxygen atoms in each nitrate (NO3) group, and there are 2 nitrate groups in Ba(NO3)2.
Barium hydroxide (Ba(OH)2) has 3 atoms: 1 barium atom (Ba) and 2 hydroxide groups, each consisting of 1 oxygen atom (O) and 1 hydrogen atom (H).
It has 6 oxygen atoms.
To find the number of atoms in 3Ba(CLO3)2, first determine the composition of one molecule of Ba(CLO3)2. It contains 1 barium (Ba), 2 chlorine (Cl), and 6 oxygen (O) atoms, totaling 9 atoms per molecule. Therefore, in 3Ba(CLO3)2, there are 3 × 9 = 27 atoms.
9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
In barium chlorite, Ba(ClO2)2, the oxidation state of barium (Ba) is +2. Each chlorite ion (ClO2-) has a charge of -1. Within the chlorite ion, the oxidation state of oxygen is -2, so for two oxygen atoms, that totals -4. To balance this, the oxidation state of chlorine must be +3. Therefore, the oxidation state of Cl in Ba(ClO2)2 is +3.
A thiosulfate ion (S2O3^2-) consists of 3 oxygen atoms, 1 sulfur atom, and 2 hydrogen atoms for a total of 6 atoms.
There are 3 atoms in an oxygen molecule (O2).
There are 2 atoms and 3 molecules in oxygen.
