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.
Basically, areas without much plant life have low chlorophyll concentration. In this case, extreme climates characterizes these areas. Specifically, the desert, polar tundra, and high mountain ridges are three areas which have low chlorophyll concentrations. The main characteristics are that they have no soil, shallow soil, or soil that lacks in nutrients, which makes it not suitable for plants to grow; they also have limited water available. Since chlorophyll is contained in vegetation, any area without plants will lack chlorophyll. Hope this helps!
Answer: Desert, Polar Tundra, and High Mountain Ridges because of lack of soil or nutrient in the soil, and lack of water.
