Invasive species can do all sorts of damage to an existing ecosystem, including changing habitats and starving native animals of food and resources.
<h3>What is an invasive species?</h3>
An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.
Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitats for native wildlife.

Answer:
Specififc rotation [∝] = 0.5° mL/g.dm
Explanation:
Given that:
mass = 400 mg
volume = 10 mL
For a solution,
The Concentration = mass/volume
Concentration = 400/10
Concentration = 40 g/mL
The path length l = 20 cm = 2 dm
Observed rotation [∝] = + 40°
Specififc rotation [∝] = ∝/l × c
where;
l = path length
c = concentration
Specififc rotation [∝] = (40 / 2 × 40)
Specififc rotation [∝] = 0.5° mL/g.dm
The answer is
14.14 x 10^-2
Answer:
41.43 mL
Explanation:
First we <u>calculate the mass of NaOH in the original solution</u>:
- 25.0 % m/v means that in 100 mL of solution, there are 25 grams of NaOH.
- This means that in 5.80 mL, we would have (5.80 * 25/100) <u>1.45 grams of NaOH.</u>
Then we <u>calculate the volume of the diluted solution</u>, using the grams of NaOH (that remain the same throughout the dilution process):
- 1.45 g NaOH *
= 41.43 mL
