Answer:
C). Hydrogen, carbon, nitrogen, neon.
Explanation:
Atomic numbers are described as the number of protons in an atom's nucleus which is denoted by the letter Z. The correct order of the atomic number of the given elements from low to high would be 'Hydrogen, Carbon, Nitrogen, Neon.' <u>The atomic number of hydrogen is 1 while carbon's atomic number is 6. Nitrogen's atomic number is 7 and Neon is a noble gas having an atomic number of 10</u>. This order is correctly displayed through <u>option C</u> and hence, it is the answer.
Answer:
there is a diffrence
Explanation:
Recent research suggests a psychopath’s brain is not like other people’s. It may have physical differences that make it hard for the person to identify with someone else’s distress.
The differences can even change basic body functions. For example, when most people see blood or violence in a movie, their hearts beat faster, their breathing quickens, and their palms get sweaty.
A psychopath has the opposite reaction. He gets calmer. Kipnis says that quality helps psychopaths be fearless and engage in risky behavior.
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.
