Plzzz i dont get this you discover a chemical reaction that produces 2 moles of valuable propane for every 9 moles of carbon supplied. essentially, this is an exchange rate of 2 moles of propane for every 9 moles of carbon. if you have 1.3 moles of carbon, how many moles of propane can you produce using this reaction?

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.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

the volume increases
