Answer:
25 mol.
Explanation:
The balanced chemical equation for the reaction depicted in this question is as follows:
4Fe + 3O2 → 2Fe2O3
Based on the above balanced equation, 4 moles of Fe produced 2 moles of Fe2O3.
Hence, 50 moles of Fe will produce as follows:
50 mol Fe × 2 mol Fe2O3/4 mol Fe
= 100/4
= 25 mol of Fe2O3
Answer:
A) mass cannot enter or exit an isolated system
Explanation:
An Isolated system is both insulated and sealed. No matter or energy can neither escape into the surroundings nor enter from the surroundings
I’m pretty sure it’s D because energy measures the kinetic, thermal, electrical, chemical, nuclear and other forms.
