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.

Hope This Helps
Explanation:
South Africa is facing significant income and wealth inequality. The expectation was, after 1994, that something will improve. Only other thing that's different, though, is the oppressor's colour. There are almost as many powerful black people today as there are white folks. This seems to be a positive idea, on the surface of it. The truth isn't so sweet, though. The rich black community is not the impact of international prosperity, but has actually displaced thousands of potential South Africans who may have relocated to several other nations.
Answer:
The answer is - Inferences

The options are:
A. contaminated observations.
B. inferences.
C. distorted behaviors.
D. illusory correlations.
The answer is B- inferences
Inference can be defined as a logical conclusion which is gotten on the basis of evidence and logical reasoning and through the use of knowledge and information.
In the scenario here, it is reasonable to infer that the SUV hit the smaller car due to the evidence that the smaller car is damaged while the SUV which is bigger only has a headlight broken.
