Answer: The mass of solution of NH_4Cl is 4.86 grams.

Explanation:

In NH_4Cl, there are 1 nitrogen atom , 4 hydrogen atoms. and 1 chlorine atom.

To calculate the mass percent of element in a given compound, we use the formula:

\text{percent by mass}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100

Percent by mass of solution = 35%

Mass of solute NH_4Cl = 1.7 gram

Mass of solution  = ?

Putting values in above equation, we get:

35=\frac{1.7}{\text{Mass of solution}}\times 100

{\text{Mass of solution}}=4.86g

Hence, the mass of solution is 4.86 grams.

Which best protects animal species that are endangered due to overhunting?
jekas [21]

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.
