How does electron repulsion in the outer shell cause anions to be larger than their atoms?

Alexeev081 [22]

The anion is also larger than the atom because of electron-electron repulsion. As more electrons are added to the outer shell, and even to higher principle energy levels, the repulsion bewteen the negatively charged particles grows, pushing the shells farther from the nucleus.

for the reaction 2Fe + O2 = 2FeO, how many grams of iron oxide are produced from 8.00 mol of iron? when o2 is an excess

Luba_88 [7]

Answer:

2Fe + O₂ -------------------> 2FeO

8 mol Fe produce

8 mol Fe * 2 mol FeO / 2 mol Fe = 8 mol FeO

Mass of FeO = 8 mol FeO * 71.85 g/mol = 574.8 grams FeO

Explanation:

Having 8 mol of Iron means 8 moles of iron oxide can be produced. Each mole of iron oxide has a molecular weight of 71.85 grams. Therefore, 8 moles of iron oxide should weight 574.8 grams.
