Based on my very little knowledge of chemistry, N and H are both 1 making 2, H4 is 4 hydrogen atoms, CI is a carbon and iodine atom making 2, making 8, so,
8x3=24
Three atoms are there In the 3co
15 Fe2O3 has 2 + 3 atoms = 5 atoms Multiply the whole thing by 3 and you end up with 15 atoms.
3 nitrogen atoms.
Limestone has 5 molecule atoms
3 atoms
it is inorganic
Ammonium chloride.
It is 1 calcium atom and 2 bromine atoms which totals 3 atoms
3 CaCl2 has 3 calcium atoms and 6 oxygen atoms.
3 atoms I think.
2 Sulfur atoms and 3 Oxygen atoms
3 atoms
Three atoms are there In the 3co
7 atoms
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
15 Fe2O3 has 2 + 3 atoms = 5 atoms Multiply the whole thing by 3 and you end up with 15 atoms.
