Answer:
Option c. 2Kl + Cl2 —> 2KCl + l2
Explanation:
A balanced equation must have the same number of atoms on the reactants side and the products side. This do the fact of the postulation by the mass conservation principle that says: Atoms can neither be broken nor destroyed but can be arranged. The atoms on the left side for each element are equal. Thus, C presents a balanced equation.
1 g/mL ------------ 8.3454 lbs/gal
1.09 g/mL --------- ?
lbs/gal = 1.09 x 8.3454 / 1
ibs/gal = 9.096 / 1
= <span>9.096 lbs/gal</span>
