I believe that Isotopes of elements have different atomic masses. So A) Atomic masses.
Answer:
359 grams FeO
Explanation:
To find how many grams FeO are produced, you need to use the moles of Fe, convert it to moles of FeO (using the mole-to-mole ratio from the equation), then convert the moles of FeO to grams (using the molar mass from the periodic table).
2 Fe + O₂ --> 2 FeO
Molar Mass (FeO) = 55.845 g/mol + 16.00 g/mol
Molar Mass (FeO) = 71.845 g/mol
5.00 moles Fe 2 moles FeO 71.845 grams
---------------------- x ------------------------ x ---------------------- = 359 grams FeO
2 moles Fe 1 mole FeO
A. A piece of Iron being heated until it melts
Because it goes from solid to liquid.
A physical change is changing from solid to a liquid, a liquid to a gas, a gas to a liquid, a liquid to a solid, a solid to a gas, or a gas to a solid.
