Hi there. I suggest doing this yourself but here are my answers in my own words
1) Using renewable resources might be an amazing choice due to the fact that there will be less pollution. If humans continue using non-renewable resources, humans will make the oxygen contaminated. Also, renewable resources will never run out so there isn't any harm getting them
2) The environmental impact of using non-renewable resources is that more carbon dioxide will be released which causes pollution which is harmful to the human body. Renewable resources are unlimited and don't cause any pollution
I think the answer is Reflected, but I may be wrong.
I think the correct answer among the choices listed above is the second option. The observation which illustrates the law of conservation of mass is that wh<span>en 3 g of carbon reacts with 8 g of oxygen, 11 g of carbon dioxide is produced. Other choices doesn't shows that mass in is equal to the mass out.</span>
Na₂CO₃(s) → 2Na⁺(aq) + CO₃²⁻(aq)
The sodium carbonate formed from a strong base and a weak acid. Hydrolysis is subjected to the anion of a weak acid.
CO₃²⁻ + H₂O ⇄ HCO₃⁻ + OH⁻
HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻
pH>7 alkaline solution
2Na⁺ + CO₃²⁻ + 2H₂O ⇄ 2Na⁺ + 2OH⁻ + H₂CO₃
Answer:
The number of carbon atoms is twice the number of magnesium atoms
