Answer:
Matter is the term for any type of material. Matter is anything that has mass and takes up space. At a minimum, matter requires at least one subatomic particle, although most matter consists of atoms.
Some examples are: Water, books, pencils, sun, earth, moon, electron, proton, mesons, and quarks
The answer is "c" because solidification or freezing is the term used for the process in which a liquid becomes a solid.<span> Freezing is an exothermic process that also is an example of a phase transition</span>
Answer:
The answer to your question is limiting reactant = Fe
Explanation:
Data
moles of Fe = 2
moles of O₂ = 6
Process
1.- Write the balanced chemical reaction
Fe + O₂ ⇒ Fe₂O₃
Reactants Elements Products
1 Fe 2
2 O 3
4Fe + 3O₂ ⇒ 2Fe₂O₃
Reactants Elements Products
4 Fe 4
6 O 6
2.- Use the balanced chemical reaction to determine the limiting reactant.
Theoretical proportion of reactants 4 moles Fe / 3 moles O₂ = 1.33
Experimental proportion of reactants = 2 moles Fe/6 moles O₂ = 0.333
3.- Conclusion
As the experimental proportion was lower than the theoretical we conclude that the amount of Fe was lower in the experiment which is the limiting reactant.
