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.
Answer: A.
Explanation:
Scientists disproved the theory of Spontaneous generation by creating experiments that showed living things cannot arise from nonliving material. An example of this is the flask experiment conducted by Louis Pasteur.
The electron has a negative charge
the neutron has a neutral charge
the proton has a positive charge
i remember this like
neutron-NEUtral
proton-POsitive
electron-electricity hurts it always has NEGATIVE effects
The answer is B because isotopes have the same number of protons and neutrons.
