Answer:
The most recent Global Burden of
Disease (GBD) study estimates that air pollution – indoor and outdoor combined – was the cause of 5.5 million premature deaths
globally in 2013. Air pollution also has further consequences on human health, leading in particular to an increasing number of
respiratory and cardiovascular diseases. Moreover, it affects crop yields and the environment, with impacts on biodiversity and
ecosystems, amongst others. These impacts have significant economic consequences, which will affect economic growth as well as welfare

Answer:
The answer to your question is: 68.3%
Explanation:
Urea = ?
Theoretical yield
Ammonia 145.1 kg
Carbon dioxide = 211.4 kg
Urea = 174.9 kg
MW NH3 = 17kg
MW CO2 44 kg
MW Urea = 60 kg
2NH₃(aq) + CO₂(aq) → CH₄N₂O(aq) + H₂O(l)
34 44 kg 60kg
145.1 211.4 174.9
Limiting reactant = NH3
34kg of NH3 ------------------ 60 kg of Urea
145.1 kg ------------------- x
x = (145.1 x 60) / 34
x = 256 kg of Urea
Percent yield = 174.9 / 256 x 100
= 68.3%
