Earthquakes can cause massive distruction that can even cause death. In order to prevent any damage done to you, you must leave the scene immediatly, especially since an earthquake can tear down houses and buildings
Answer:
Oxygen is the limiting reactant.
Explanation:
Based on the reaction:
C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O
<em>1 mole of sucrose reacts with 12 moles of oxygen to produce 12 moles of CO₂ and 11 moles of H₂O.</em>
<em />
10.0g of sucrose (Molar mass: 342.3g /mol) are:
10.0g C₁₂H₂₂O₁₁ × (1mole / 342.3g) = 0.0292 moles of C₁₂H₂₂O₁₁
And moles of 10.0g of oxygen (Molar mass: 32g/mol) are:
10.0g O₂ × (1mole / 32g) = 0.3125 moles of O₂
For a complete reaction of 0.0292 moles of C₁₂H₂₂O₁₁ you need (knowing 12 moles of oxygen react per mole of sucrose):
0.0292 moles of C₁₂H₂₂O₁₁ × (12 moles O₂ / 1 mole C₁₂H₂₂O₁₁) = <em>0.3504 moles of O₂</em>
As you have just 0.3125 moles of O₂, <em>oxygen is the limiting reactant.</em>
Answer:
D. As pure elements because most elements are unreactive.
Explanation:
This is because, like the answer says. Grass isnt really a toxic chemical that can explode and turn into iron or something when it touches water. And most natural elements are pure.
According to the second law of thermodynamics, heat energy released by an organism is released into the <span>environment and unusable. This energy is also known as entropy which is defined as the tendency of things to be dispersed and spontaneous. This means that entropy is always random and becomes unavailable energy.</span>
