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>
Answer
is: concentration
ammonia is higher than concentration of ammonium ion.<span>
Chemical reaction of ammonia in water: NH</span>₃ + H₂O →
NH₄⁺ + OH⁻.<span>
Kb(NH</span>₃) = 1,8·10⁻⁵.<span>
c</span>₀(NH₃) = 0,8 mol/L.<span>
c(NH</span>₄⁺) =
c(OH⁻) = x.<span>
c(NH</span>₃) =
0,8 mol/L - x.<span>
Kb = c(NH</span>₄⁺) · c(OH⁻) /
c(NH₃).<span>
0,000018 = x² / 0,8 mol/L - x. </span>
<span>x</span>² + 0,000018x - 0,0000144 = 0.
<span>
solve quadratic equation: x = c(NH</span>₄⁺) = 3,79·10⁻<span>³ mol/L.</span>

Answer: true
Explanation:
All living things need food to provide materials for growth. ... A food chain typically only has a few steps (usually 4 at the most). This is because each time one organism eats another, some of that energy is used up and released as heat.
