Ava and Eddy are discussing the difference between a species being extinct and an endangered species. Ava states that extinction
12345 [234]

In biology the term extinct is used for species which are no longer alive. so here Ava is correct because a species has died out and is not longer alive.

Endangered species are those which are on the urge of being extinct, means they are in danger so the term "endangered"

Ava can also elaborate the terms by taking examples

Dinosaurs are extinct species. They are no longer alive or not found in any part of world. So they are called as extinct.

The term can be used for animal or plant species.

How would you convert 500cc of 2M H2so4 in g/l and normality?​
Ann [662]

Concentration :

196 g/L and 4 N

<h3> </h3><h3>Further explanation</h3>

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.

500 cc of 2M H₂SO₄

V = 500 cc = 0.5 L

mol H₂SO₄

\tt mol=M\times V=2\times 0.5=1

mass H₂SO₄ (MW = 98 g/mol)

\tt mass=mol\times MW=1\times 98=98~g

concentration in g/L :

\tt \dfrac{98}{0.5}=196~g/L

concentration in normality

Relationship between normality and molarity

N = M x n (n=valence , amount of H⁺ or OH⁻)

so :

\tt N=2\times 2(n=2~for~H_2SO_4\rightarrow 2H^+)\\\\N=4
