5.78 Nitric acid is produced from nitrogen monoxide No which in turn is prepared from ammonia by the Ostwald process: 4NH3(g) + 502(g) → 4NO(g) + 6H,0(g) What volume of oxygen at 35°C and 2.15 atm is needed to produce 100.0 g of nitrogen monoxide?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Question 78
![**Chemistry Exercises on Gas Reactions and Balancing Equations**
**5.77** Urea, NH₂CONH₂, is a nitrogen fertilizer that is manufactured from ammonia and carbon dioxide.
\[ 2\text{NH}_3(g) + \text{CO}_2(g) \rightarrow \text{NH}_2\text{CONH}_2(s) + \text{H}_2\text{O}(l) \]
*Question:* What volume of ammonia at 25°C and 4.00 atm is needed to produce 908 g (2 lb) of urea?
---
**5.78** Nitric acid is produced from nitrogen monoxide, NO, which in turn is prepared from ammonia by the Ostwald process:
\[ 4\text{NH}_3(g) + 5\text{O}_2(g) \rightarrow 4\text{NO}(g) + 6\text{H}_2\text{O}(g) \]
*Question:* What volume of oxygen at 35°C and 2.15 atm is needed to produce 100.0 g of nitrogen monoxide?
---
**5.79** Ammonium sulfate is used as a nitrogen and sulfur fertilizer. It is produced by reacting ammonia with sulfuric acid.
*Task:* Write the balanced equation for the reaction of gaseous ammonia with sulfuric acid solution. What volume (in liters) of ammonia at 15°C and 1.15 atm is required to produce 150.0 g of ammonium sulfate?
---
**5.80** Sodium hydrogen carbonate is also known as baking soda. When this compound is heated, it decomposes to sodium carbonate, carbon dioxide, and water vapor.
*Task:* Write the balanced equation for this reaction. What volume (in liters) of carbon dioxide is produced at 100°C and 1.00 atm from the decomposition of 168 g of sodium hydrogen carbonate?
---
These exercises involve chemical reactions, stoichiometry, and gas laws, focusing on the practical applications of fertilizers and everyday compounds like baking soda. Each problem requires a balanced chemical equation and calculations involving the ideal gas law to determine the volume of gases under specified conditions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F123a0496-a906-4574-8cea-2b52f1a94eb4%2F05295e26-9400-40a6-bf7e-86d426fd8e17%2Ft29p8r.jpeg&w=3840&q=75)
