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 American civil rights movement started in the mid-1950s. A major catalyst in the push for civil rights was in December 1955, when NAACP activist Rosa Parks refused to give up her seat on a public bus to a white man. Read about Rosa Parks and the mass bus boycott she sparked.
Explanation:
Research are likely to suggest that competitive encounters are likely to be more hard working while the collaborative encounters are the ones who will likely give their time to cooperate. It is because competitive encounters are usually competitive in a way of reaching their tasks or goals while the collaborative encounters are likely to just cooperate because of their knowledge with the given task.
Answer:
Autocracy is a system of government in which supreme power over a state is concentrated in the hands of one person, whose decisions are subject to neither external legal restraints nor regularized mechanisms of popular control (except perhaps for the implicit threat of coup d'état or other forms of rebellion).
