2Ni3(PO4)2
Nickel phosphate.
6 nickel atoms
4 phosphorous atoms
16 oxygen atoms
Now, this
PO4 3-
is the polyatomic ion phosphate and is internally covalently bonded, so it could be called a molecule, though it is charged.
there are 2 PO4 3-
12, since in one benzene molecule there are 6 atoms in 2 molecules of benzene there will be 6*2 atoms
There are 3 atoms bro. NO3 means 3 atoms of oxygen. NO2 means 2 atoms of oxygen. NO means 1 atom of oxygen.
There are 2 oxygen atoms in dioxide
There are 2 atoms and 3 molecules in oxygen.
Matter is not created nor destroyed in chemical reactions, the total mass and number of atoms before the reaction equals the total number of atoms and mass after the reaction. Conservation of mass law.
2 hydrogen atoms and 1 oxygen atom
6 hydrogen molecules 2 carbon molecules 1 oxygen molecules
To determine the total number of atoms and molecules in 5H2SO4, we first need to break down the chemical formula of sulfuric acid (H2SO4): 1 molecule of H2SO4 contains: 2 atoms of hydrogen (H) 1 atom of sulfur (S) 4 atoms of oxygen (O) Therefore, in 5 molecules of H2SO4, we have: 5 x 2 atoms of hydrogen = 10 hydrogen atoms 5 x 1 atom of sulfur = 5 sulfur atoms 5 x 4 atoms of oxygen = 20 oxygen atoms So, in total, there are 10 hydrogen atoms, 5 sulfur atoms, and 20 oxygen atoms in 5 molecules of H2SO4. Additionally, to find the total number of molecules in 5H2SO4, we simply multiply the coefficient (5) by the number of molecules in the formula (1 H2SO4 molecule) to get: 5 x 1 = 5 molecules of H2SO4. Therefore, in 5H2SO4, there are: 10 hydrogen atoms 5 sulfur atoms 20 oxygen atoms 5 molecules of H2SO4.

There are 3 atoms bro. NO3 means 3 atoms of oxygen. NO2 means 2 atoms of oxygen. NO means 1 atom of oxygen.
Water is H2O and hydrogen peroxide is H2O2 ; both of these molecules have two hydrogen atoms. It is the number of oxygen atoms which varies.
A mole of H2 molecules contains 6.023 x 10^(23) H2 molecules or 2 moles of H atoms (since each molecules has 2 atoms). A mole of CaCO3 (calcium carbonate) has one mole (Avogadro number) of Ca atoms, one mole of C atoms and 3 moles of O atoms.
Molecules are combinations of multiple atoms. In a chemical reaction, the bonds between the atoms are broken and new ones form, usually with a lower amount of energy than when they started. In a reaction such as synthesis of hydrogen (H2) and Oxygen (O2) to form water (H2O), the formula would look like this- 2(H2)+(O2)=2(H2O). there are there are three molecules on the left and two on the right. however the number of atoms are the same.
The number of hydrogens equals 2x the number of carbon atoms, plus 2 extra hydrogens.
The number of molecules is 3,011.10e23.
H2SO4 is Sulfuric Acid. If it has the number 2 in front of the whole compound it means there are two molecules in the reaction. The number of atoms in 1 molecule is (2 x hydrogen, 1 x sulfur, 4 x oxygen), therefore in two molecules there are 4, 2 and 8 respectively which gives a total of 14 atoms.
11 atoms, 2 oatssium, 2 chromium, 7 oxygen. No molecules as such. 2 K+ and the polyatomic anion Cr2O72-.
