Answer:
9 grams of methane contains a greater number of hydrogen atoms (therefore molecules) than 10 grams of ammonia
Explanation:
The number of atoms of hydrogen per molecule of ammonia = 3 atoms of hydrogen
The number of atoms of hydrogen per molecule of methane = 4 atoms of hydrogen
The molar mass of methane = 16.04 g/mol
The molar mass of ammonia = 17.031 g/mol
The number of moles of methane in 9 grams of methane = 9/16.04 ≈ 0.561 moles
The number of hydrogen atoms in 0.561 moles of methane = 0.561 × 6.02 × 10²³ × 3 ≈ 1.351 × 10²⁴ atoms of hydrogen
The number of moles of ammonia in 10 grams of ammonia = 10/17.031 ≈ 0.5872 moles
The number of hydrogen atoms in 0.5782 moles of ammonia = 0.5872 × 6.02 × 10²³ × 3 ≈ 1.06 × 10²⁴ atoms of hydrogen
Therefore, 9 grams of methane contains a greater number of hydrogen atoms than 10 grams of ammonia.
Answer:
The Zhou Dynasty (1046-256 BCE) was among the most culturally significant of the early Chinese dynasties and the longest lasting of any in China's history. It is divided into two periods: Western Zhou (1046-771 BCE) and Eastern Zhou (771-256 BCE). It followed the Shang Dynasty (c. 1600-1046 BCE), whose cultural contributions it developed, and preceded the Qin Dynasty(221-206 BCE, pronounced “chin”) which gave China its name. Among the Shang concepts developed by the Zhou was the Mandate of Heaven – the belief in the monarch and ruling house as divinely appointed – which would inform Chinese politics for centuries afterwards and which the House of Zhou invoked to depose and replace the Shang.
The Western Zhou period saw the rise of decentralized state with a social hierarchy corresponding to European feudalism in which land was owned by a noble, honor-bound to the king who had granted it, and was worked by peasants. Western Zhou fell just before the era known as the Spring and Autumn Period (c. 772-476 BCE), named for the state chronicles of the time (the Spring and Autumn Annals) notable for its advances in music, poetry, and philosophy, especially the development of the Confucian, Taoist, Mohist, and Legalist schools of thought.

Answer:
Germany's Schlieffen strategy was intended to force France into submission and to make France to comply and conquer Russia afterwards. It didn't work as Russian soldiers targeted Germany as German troops invaded France. The man who planned it was General Alfred von Schlieffen, the Chief of Staff of Germany.
