Physical trait is the major limitation present in the current classification system.
Explanation:
- Classification is the process through which we see the relationship between various things.
- During classification we categorize things that helps us to make a proper subjective judgement.
- The limitation of classifications are they are biased , that is who are participating may not have same physical traits.
- As a result difference occurs in perceived value. Another huge problem is human beings make classification for satisfying their own purpose .
- The natural world behaves in its own way that is by not following any classification.
Answer:
0.200g de gas son obtenidos
Explanation:
La reacción de ácido clorhídrico, HCl, con Zn es:
2HCl(aq) + Zn(s) → ZnCl₂(s) + H₂(g)
<em>Donde 2 moles de ácido reaccionan con 1 mol de Zn para producir una mol de cloruro de cinc y una mol de hidrógeno (gas)</em>
Asumiendo que el ácido está en exceso, las moles de 6.5g de Zn (Masa molar: 65.38g/mol) son:
6.5g × (1mol / 65.38g) = <em>0.0994 moles de Zn</em>
Como 1 mol de Zn produce 1 mol de hidrógeno, las moles de hidrógeno son 0.0994 moles de H₂. En gramos (Masa molar H₂ = 2.01g/mol):
0.0994 moles H₂× (2.01g / mol) = <em>0.200g de gas son obtenidos</em>
Answer: oil spill, forest fire
Explanation:
The short term environmental change is a change that occur in an environment which exerts it's effect over the environment and the living beings for a short duration. The damage caused by the short term environmental change can be recovered in a short time. The oil spill and forests fire are the example of short term environmental changes.
The oil spill will reduce the abundance of the aquatic species until the oil is circulated out at the bay of the water body therefore, it is a short term environmental change.
Forests fire will remain ignited for a short period but can be destructive enough to cause damage to flora and fauna species. As time passes the reduced populations of flora and fauna can be recovered again.
