What is the sum of the coefficients when the equation is balanced with the smallest whole numbers? __BaCl2 + __Fe2(SO4)3 → __FeCl3 + __BaSO4 *?

In numbering carbon atoms in the parent chain of a hydrocarbon, why would you number from right to left, rather than left to right

8. what happens to matter during a chemical reaction

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall. (use the words "first, second, third, fourth" to fill each blank)experimentinitial conc of a, mol/l initial conc of b, mol/l initial conc of c, mol/l initial rate, mol/l.s1 0.1 0.1 0.2 2 x 10-32 0.2 0.3 0.2 6 x 10-33 0.3 0.1 0.2 2 x 10-34 0.4 0.3 0.4 1.2 x 10-2
