Answer:

an abandoned field, a cooling lava flow, a valley under a glacier, and an unused farm

Explanation:

Primary succession happens in a place where there is no soil cover or it is removed.

an abandoned field- Secondary; because there is cover of soil left, even if vegetation is removed.

a cooling lava flow- Primary; volcanic events lead to loss of soil layer, so this would lead to primary succession

a valley under a glacier- Primary; retreating glaciers are lead to primary succession

an unused farm-Secondary; the soil cover is still present

a burnt forest- Secondary; soil cover is still left for vegetation to start over again

a deserted mine- Primary; because there would be barren rocks left, so soil would be formed by pioneer species first.

A solution of H2SO4(aq) with a molal concentration of 4.80 m has a density of 1.249 g/mL. What is the molar concentration of thi

Naddika [18.5K]

Imagine we have mass of solvent 1kg (1000g)
According to that: $molality =n(solute) / m(solvent) =\ \textgreater \ 4.8m = 4.8mole / 1kg$
= 4.8 mole * 98 g/mole = 470g
$m(H2SO4) = n(H2SO4)*Mr(H2SO4) =\ \textgreater \$ $=\ \textgreater \ Molarity = 4.8 mole / 1.2 L = 4 M$ m(H2SO4) which is =470g

m(solution) = m(H2SO4) + m(solvent) = 470 + 1000 = 1470 g
d(solution) = m(solution) / V(solution) =>
=> 1.249 g/mL = 1470 g / V(solution) =>
$Molarity = n(solute) / V(solution) =\ \textgreater \$
