Answer:
chemical
Explanation:
Chemical weathering, which is the decomposition of a rock by the alteration of its chemical composition.
The balanced chemical reaction is:
<span>2 Al (s) + 3 Fe(NO3)2 (aq) = 3 Fe (s) + 2 Al(NO3)2 (aq)
</span>
The ratios or the coefficients between the reactants and the products will be used for further calculations.
305 g Fe(NO3)2 solution (.755) = 230.275 g <span>Fe(NO3)2
</span> 230.275 g Fe(NO3)2 ( 1mol / 179.87 g) ( 3 mol Fe / 3 mol <span>Fe(NO3)2) ( 55.85 g / mol) = 71.500 g Fe</span>
