The MOLAR RATIO or Coefficient. Do NOT confuse with numbers AFTER the chemical symbols. e.g. 2NaOH + H2SO4 = Na2SO4 + 2H2O The Molar Ratios (Coefficients) are in order from left to right ' 2:1 :: 1:2 '. In Na2SO4 the numbers '2' refers to TWO sodium atoms And '4' refers to FOUR oxygen atoms. In '2H2O'. The left hand '2' refers to TWO molar ratios. The '2' to the right of 'H' (Hydrogen) refers to each molecule having two (2) hydrogen atoms. NB When no number is shown, read it as '1'(one). This applies to molar ratios and to atom numbers in a molecule. e.g. NaOH ; No numbers, so there is only ONE of each atom. Similarly, H2O means only ONE(1) atom of oxygen, in the molecule.
The chemical symbol for element number 33 is As, which stands for arsenic.
