Answer:
Invasive species, runoff pollution, and climate change.
Explanation:
Invasive species, such as Burmese pythons, threaten the Florida Everglades because they are not native to the natural habitat. Pythons eat the native animals, but they don't have any predators.
Pollution from nearby farms and roads enters the water and damages the ecosystem of the Everglades and Louisiana wetlands. Toxic chemicals lead to detrimental effects for both humans and wildlife.
Humans have drained swampy areas to allow for development. However, this has led to the Everglades drying up and even burning in recent years.
The answer is selenium which is D
Answer:
True
Explanation:
You must first observe your data then form a hypothesis.
Answer:
23 g of Zn will produce 0.352 mole of zinc chloride.
Explanation:
Given data:
mass of Zn = 23 g
Moles of ZnCl = ?
Solution:
Chemical equation:
2Zn + CuCl₂ → 2ZnCl + Cu
Number of moles of Zn:
<em>Number of moles of Zn = mass/ molar mass</em>
Number of moles of Zn = 23 g / 65.38 g/mol
Number of moles of Zn = 0.352 mol
now we will compare the moles of ZnCl with Zn because it is limiting reactant.
Zn : ZnCl
2 : 2
0.352 : 0.352
So 23 g of Zn will produce 0.352 mole of zinc chloride.
