Answer:
Captive breeding
Explanation:
Endangered species, such as the Black Rhino, Saola, Cross River Gorrillas, the Blue Whale, and a host of others, are species that are critically under the verge of extinction either as a result of the destruction of their habitat or poaching/overhunting, which has really led to steep decline in their population.
Several attempts have been made and ate being made to ensure the preserve and protect these endangered species form going extinct.
However, the best of such measures or practices is arguably referred to as Captive Breeding.
Captive breeding involves the capturing of some of these endangered species and transporting them to enclosed and monitored facilities such as zoos in other to promote the increase preservation and survival of these species and ensuring they don't go extinct.
In most cases, when a considerable increase in population in these facilities is established through breeding, some of them are later on reintroduced to their natural habitat in the wild. This do not only ensure biodiversity, it also ensures the population of the endangered species to grow and avoid such species from going extinct.
Answer:
Reactants: Ethanol (C₅H₅OH), Oxygen (O₂)
Products: Carbon dioxide (CO₂) and Water (H₂O)
Explanation:
Let’s rewrite each part of the described situation in chemical equation terms.
Ethanol - C₂H₅OH
is burned in the prescence of - +
oxygen - O₂
producing - →
carbon dioxide - CO₂
and - +
water - H₂O
Chemical equation:
C₂H₅OH + O₂ → CO₂ + H₂O
The terms on the left side of a chemical equation are reactants, and the terms on the right side of a chemical equation are products.
Therefore, since we know this, ethanol (C₂H₅OH) & oxygen (O₂) are the reactants, and carbon dioxide (CO₂) & water (H₂O) are the products.
Answer:
The final temperature of sulfur dioxide gas is 215.43 C
Explanation:
Gay Lussac's Law establishes the relationship between the temperature and the pressure of a gas when the volume is constant. This law says that if the temperature increases the pressure increases, while if the temperature decreases the pressure decreases. In other words, the pressure and temperature are directly proportional quantities.
Mathematically, the Gay-Lussac law states that, when a gas undergoes a transformation at constant volume, the quotient of the pressure exerted by the temperature of the gas remains constant:
Assuming you have a gas that is at a pressure P1 and at a temperature T1 at the beginning of the experiment, by varying the temperature to a new value T2, then the pressure will change to P2, and it will be true:
The reference temperature is the absolute temperature (in degrees Kelvin)
In this case:
- P1= 0.450 atm
- T1= 20 C= 293.15 K (being 0 C= 273.15 K)
- P2=0.750 atm
- T2= ?
Replacing:
Solving:
T2=488.58 K
Being 273.15 K= 0 C, then 488.58 K= 215.43 C
<u><em>The final temperature of sulfur dioxide gas is 215.43 C</em></u>
