It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
3
3 or 9
8
Exactly one million. insanely small, right?
There are three atoms.One copper atom and two chlorine atoms.
2
I believe it is 4. 1A+1G+2O 1+1+2=4
by using many, many, many large and small boats................
3H2O has 6 hydrogen atoms and 3 oxygen atoms.
9
3 Hydrogen atoms, 2 Oxygen atoms.
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
2NaAlO 2+3h2O
In 3 molecules of H2O, which is 3H2O, there are 6 hydrogen atoms and 3 oxygen atoms. You multiply the coefficient of 3 times the subscript of each element. When there is no subscript, it is assumed to be 1.
The 3 means there are 3 molecules of H2O (water), and the 2 is a subscript and means there are 2 atoms of hydrogen (H) in one molecule.
BeC2O4 = 97.0 g/1 mol BeC2O4-3H2O = 151.0 g/1 mol 3.21 g BeC2O4-3H2O * 1 mol/151.0 g = 0.021258 mol BeC2O4-3H2O 0.021258 mol BeC2O4-3H2O * 97.0 g/1 mol = 2.06 g BeC2O4
The numbers of sodium, oxygen, and hydrogen atoms are the same on both sides of the equation.
3 molecules of water
ITS: CH3COONa --> CH3COO- + Na+ Or if its CH3COONa . 3H2O --> CH3COONa + 3H2O
The balanced equation is Al(OH)3 + 3HCl ==> 3H2O + AlCl3
