What is the difference between an introduced species and an invasive species?

a_sh-v [17]

Answer and Explanation:

The introduced species is, literally, a species that was introduced into an environment by human action. In other words, an introduced species is one that is not native to a region, does not occur naturally, but has been taken by humans to that region.

An invasive species, on the other hand, is one that was introduced naturally in an environment, but multiplied in a harmful way, causing a strong imbalance in the region.

If you have 3 moles of FeCl3, how many moles of MgCl2 can be produced? FeCl3 + Mg --> MgCl2 + Fe

oksian1 [2.3K]

Answer: 154.09 g

Explanation:

3 Mg + 2 FeCl3 = 3 MgCl2 + 2 Fe

The mass of MgCl2 produced is calculated:

m MgCl2 = 175 g FeCl3 * (1 mol FeCl3 / 162.2 g) * (3 mol MgCl2 / 2 mol FeCl3) * (95.21 g MgCl2 / 1 mol) = 154.09 g

As the temperature of a medium increases, the speed of the sound wave

Irina-Kira [14]

Answer : As the temperature of a medium increases, the speed of the sound wave increases because the particles bump into each other more often.

Explanation :

The dependency of the speed of the sound wave and the temperature of the medium is :

$v=\sqrt{\gamma\ R\ T}$

Where

$\gamma$ = ratio of specific heat

R is gas constant

T is the temperature

The speed of the wave is directly proportional to the temperature. As the temperature of a medium increase, the speed of the sound increase. The particles start vibrating faster. Hence, they bump into each other.

Hence, the correct option is (A).
