Answer:
See below.
Explanation:
I'll do the second row for you the other 2 are done in exactly te same way.
B. Area of 1 side of cube = 2*2 = 4.
Surface area = 4*6 = 24
Volume = 2*2*2 = 8.
Surface area / volume = 24/8 = 3.
Ratio of Suface Area to Volume = 24 : 8 = 3 : 1. (divide both by 8)
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>
It is B because you can’t really makes any guesses together
