Consider the unbalanced reaction,
H₂ + N₂ ===> NH₃
Balance it to get
3 H₂ + N₂ ===> 2 NH₃
This tells you that for every 3 moles of H₂ and 1 mole of N₂ among the reactants, 2 moles of NH₃ are produced.
Look up the molar masses of each component element:
• H : 1.008 g/mol ===> H₂ : 2.016 g/mol
• N : 14.007 g/mol ===> N₂ : 28.014 g/mol
• NH₃ : 17.031 g/mol
Convert the given mass to moles for each reactant:
• H₂ :
(5.22 kg) × (1000 g/kg) × (1/2.016 mol/g) ≈ 2589.29 mol
• N₂ :
(31.5 kg) × (1000 g/kg) × (1/28.014 mol/g) ≈ 1124.44 mol
Now,
(2589.29 mol H₂) : (1124.44 mol N₂) ≈ (2.30 mol H₂) : (1 mol N₂)
so that the amount of N₂ consumed is
(2589.29 mol H₂) × (1 mol N₂) / (3 mol H₂) ≈ 863.095 mol N₂
leaving an excess of about 261.343 mol N₂, and producing
(2589.29 mol H₂) × (2 mol NH₃) / (3 mol H₂) ≈ 1726.19 mol NH₃
Convert this to a mass :
(1726.19 mol) × (17.031 g/mol) × (1/1000 kg/g) ≈ 29.3987 kg
So, up to 29.4 kg of NH₃ can be synthesized.
Praise is simply known as expressing one's respect, gratitude or appreciation to what another person has done for you. The author's praise of Secretary John Sherman is because she wants To show readers that John Sherman is an ally, not an enemy, despite his objections to Cuba's acquisition and war with Spain.
- John Sherman was known to be a popular politician from the U.S. State. He existed during the American Civil War and into the late nineteenth century. He was a member of the Republican Party, and was U.S. Congress.
The author praises Secretary Sherman due to the part he had played as the Secretary of State during the Presidency of President William McKinley in 1897. The secretary was known to play a key role in smoothing relationships with China.
Conclusively, Secretary John Sherman was known for his well-meaning opposition to some of the foreign policies that existed then as Secretary of the Treasury and Secretary of State.

Answer:
Death Valley’s crazy heats are caused by a combination of the lack of water, geography, and materials that make up the valley.
The average yearly rainfall in Death Valley is only 2 inches. This is less than many other deserts in the world, averaging around 10 inches of rain annually. This intense lack of water also creates a lack of plants in the area resulting in the expanses of sand in the valley open to constant heating by the sun.

Sea level in Death Valley
Driving into the valley you get to experience the geography of the environment, traveling from 1000 feet to 4000 feet above sea level and down to 100 feet below sea level. These mountain ranges you drive over top 4000 feet and surround the lowest point in the United States of 282 feet below sea level. This creates an interesting phenomenon of trapping the hot air within the valley.
Sand and rocks make up the valley floor which radiate a large amount of heat. However, because of the geography, this hot air cannot escape. Instead, the hot air rises along the valley walls, cools slightly and then falls back to the valley floor to be heated even more by the hot sand and low elevation air pressure. This concept of movement by heating and cooling is called convection and exists in many other life circumstances like the boiling of water or in a kitchen oven. Despite the movement of air and possibility of high winds, the winds do not do much to cool down the hikers in the valley because the wind is still very hot.
The heat can be so extreme that signs in the park advise turning off the air conditioning in certain areas to avoid overheating of cars, making the experience an even toastier one. Additionally, hiking is recommended only before 10am and with lots of water.
Despite the heat it is worth braving the heat to experience the truly unique views of Death Valley. This unique environment allows for rock formations, salt flats and expanses unlike anything else in the United States.
