n(2Fe2O3)=10g/319.374amu=0.03mol
n(4Fe+3O2)=0.03 mol
m(4Fe+2O2)=Mn=319.374×0.03=9.58=10
It is a. oxidation-reduction
Answer:
The environment Ecosystems are also affected by climate change. Habitats are being modified, the timing of events such as flowering and egg laying are shifting, and species are altering their home ranges. Changes are also occurring to the ocean.
Explanation:
Elements in a group or a column have the same number of outer electrons so they have similar chemical properties
C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)
molar ratio of H2O to O = 6:8
<span>we have 0.200 moles of H2O so we need 0.200 * 8/6 moles of O2 = 0.267 moles of O2
Therefore, there will be 0.267 moles of O2 gas required to yield 0.2 moles of H20.
