Let's break it down:
Al3 = 3 atoms
02 = 2 atoms
Add that up = 5 atoms
Since the coefficient is 2, we multiply that by 2
Hence there are 10 atoms
Maybe 10 if you are in AOA like me then ask one of the teachers to help
0.00000000003 * 2 = 0.00000000006 atoms of oxygen (which is 0.00000000003 molecules of O2)
Most oxygen molecules are composed of two atoms of oxygen, and we frequently refer to oxygen as O2 (or O2) for this reason. Oxygen can also exist as the molecule called ozone, which is O3. Ozone is unstable, and will revert to O2 in a few minutes.
2H2 + O2 ---> 2H20 is balanced when total numbers of atoms of EACH element seperately are equal on both sides ('Reactant' and 'Product' side): Left (2x H2=) 4 H atoms and (1x2 O=) 2 O atoms Right (2x H2=) 4 H's and (2x1 O=) 2 O's
6 atoms of oxygen are present. Three O2 contains 6 O atoms.
The coefficients in front of the reactants and products tell you how many atoms or molecules take part in a reaction. For example, the chemical equation 2 H2 plus O2 produces 2 H2O means that two hydrogen atoms react with one oxygen atom to produce two water molecules.
O2 has 2 atoms of oxygen.
There are 12 atoms in 6 O2 molecules.
in the oxygen that we breath there is 2 atoms (O2)
There are two atoms of oxygen on each side.
12.54 (g O2) / 2*15.99 (g/mol O2) = 0.3921 mol O2 -->0.3921 (mol O2) * 6.022*1023 (molecules O2)/(molO2) == 2.361*1023 molecules O2= 4.723*1023 atoms O
6.02214076×1023
Each molecule of Al2S3 is composed of one Al3+ ion. Since a mole is equal to 6.022 x 1023 molecules, there would be 6.022 x 1023 Al3+ ions in one mole of Al2S3.
2 oxygen atoms.
Molecules of oxygen exist in two relatively stable allotropes: breathable oxygen with the formula O2, and ozone with the formula O3. The little number indicates that these molecules are composed of (respectively) two or three oxygen atoms.
0.00000000003 * 2 = 0.00000000006 atoms of oxygen (which is 0.00000000003 molecules of O2)
It can carry a maximum of 4 Oxygen molecules (1 O2 per Heme group). 1 O2 molecule is made up of 2 oxygen atoms. 4 molecules x 2 atoms = 8 atoms of oxygen per saturated haemoglobin
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
