![]() ![]() When these two conditions are met, the equation is said to be balanced. Also the sum of the charges on one side of the equation must be equal to the sum of the charges on the other side. This means that a chemical equation must have the same number of atoms of each element on both side of the equation. The Law of Conservation of Mass states that mass is neither created nor destroyed in an ordinary chemical reaction. From understanding avagadro’s contact, to mole calculations, formula’s for percentage yield and atom economy, at first this part of the GCSE chemistry syllabus seems very difficult. ![]() If the elements in a chemical formula are properly capitalized, the smart case converter leaves them as you have typed.Ī balanced chemical equation accurately describes the quantities of reactants and products in chemical reactions. Chemical Calculations and Moles GCSE chemistry equations, formulae and calculations are often the part of the syllabus that many students struggle with. The equation can be written in lowercase letters.To enter the equation sign, you can use either "=" or "->" or "→" symbols.To enter charge species, just type them as they are, for example Hg2+, Hg22+, or Hg2^2+.All types of parentheses are correct, for example K3.Spaces are irrelevant, for example Cu SO 4 is equal CuSO4.Enter an equation of a chemical reaction and click 'Submit' (for example: mn2++bio3-+h+=mno4-+bi3+ ). ![]()
