Wich is greater
50% or 13/25

   13/25 is greater

Step-by-step explanation:

As  

    50%  = 50/100 = 0.5

And

    13/25 = 0.52

S0      0.5 < 0.52

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
