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.
Since most mice have thin fur, it is most likely a dominant trait. However, as the temperature decreases, the mice could adapt and their fur could become thicker.
Answer:
The structural immaturity of the infant brain makes it unlikely that such emotions can be experienced in the first year.
Explanation:
According Jerome Kagan, the brain of an infant under the age of one is still immature and, for that reason, incapable of feelings that require thought (such as, guilt, pride, despair, same, empathy, and jealousy). When a one-year-old responds to an emotional incentive, it is either with a biologically prepared response or with acquired habits. A three-year-old child, on the other hand, is capable of those feelings because she is now able to infer the state of others and to be aware of her own emotions.
