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.
Not all land was suitable for the growth of cotton.
While the south was generally good for growing cotton, it couldn't be grown everywhere. The right soil and water conditions were needed to grow cotton and preferably would be grown on a large, flat piece of land as well. Unlike cotton, rice grows best in wet soil and tobacco grew well in the climates of Virginia, Kentucky, and Tennessee.
Answer:
C.
Explanation:
From the given options, as per the time cultural time orientations, Janelle's cousin who lives in Peru is less likely to be considered about the shift in the schedule. It is because Peruvian is a Polychronic culture.
The term polychronic means to perform several tasks at the same time. A Polychronic culture is the one in which people tend to be multi-taskers. In this culture, people are more flexible with their time schedules and value long-term relationships in comparison with monochronic culture. And Peru is a Polychronic state.
So, Janelle's cousin who is from Peru will be least likely to be affected by the change in schedule (option C).
