Threats faced by the Everglades and the Louisiana wetlands.
Viefleur [7K]

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.

C + O2 = CO2
geniusboy [140]

Answer:

44 grams of CO₂ will be formed.

Explanation:

The balanced reaction is:

C + O₂ → CO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

  • C: 1 mole
  • O₂: 1 mole
  • CO₂: 1 mole

Being the molar mass of each compound:

  • C: 12 g/mole
  • O₂: 32 g/mole
  • CO₂: 44 g/mole

By stoichiometry the following mass quantities participate in the reaction:

  • C: 1 mole* 12 g/mole= 12 g
  • O₂: 1 mole* 32 g/mole= 32 g
  • CO₂: 1 mole* 44 g/mole= 44 g

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

If 12 grams of C react, by stoichiometry 32 grams of O₂ react. But you have 40 grams of O₂. Since more mass of O₂ is available than is necessary to react with 12 grams of C, carbon C is the limiting reagent.

Then by stoichiometry of the reaction, you can see that 12 grams of C form 44 grams of CO₂.

<u><em>44 grams of CO₂ will be formed.</em></u>
