What do you think the equation is for percent yield?
Why is it important to know how efficient a process is? Give at least one example.
Answers
Percent yield is the percent ratio of actual yield to the theoretical yield. It is calculated to be the experimental yield divided by theoretical yield multiplied by 100%. If the actual and theoretical yield are the same, the percent yield is 100%.
Answer:
Explanation:
Research is constantly deepening our understanding of chemistry, and leading to new discoveries. Chemistry will help us solve many future problems, including sustainable energy and food production, managing our environment, providing safe drinking water and promoting human and environmental health.
for example haber process
3H2 + N2 gives 2NH3
The process works today much like it originally did by using extremely high pressure to force a chemical reaction. It works by fixing nitrogen from the air with hydrogen from natural gas to produce ammonia (diagram). The process must use high pressure because nitrogen molecules are held together with strong triple bonds. The Haber-Bosch process uses a catalyst or container made of iron or ruthenium with an inside temperature of over 800 F (426 C) and a pressure of around 200 atmospheres to force nitrogen and hydrogen together.Today, chemical fertilizers contribute to about half of the nitrogen put into global agriculture, and this number is higher in developed countries.
