Secondary succession occurs in areas where a biological community has already existed but some or all of that community has been removed by small-scale disturbances that did not eliminate all life and nutrients from the environment.
Because its easier for scientists outside of the United States to understand your data.
<h3><u>Answer:-</u></h3>
3. <u>Proton</u> is the subatomic particle which accounts for most of an atom's mass.
4. <u>Electrons</u> are the subatomic particle which accounts for most of atoms volume.
The balanced chemical reaction is:
<span>2NH3(aq) + H2SO4(aq) = (NH4)2SO4(aq)
</span>
We are given the amount of sulfuric acid to be used for the reaction. This will be the starting point of our calculations.
60.0 mol H2SO4 ( 1 mol (NH4)2SO4 / 1 mol H2SO4 ) ( 132.14 g (NH4)2SO4 / 1 mol (NH4)2SO4 ) = 7928.4 g <span>(NH4)2SO4</span>
