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: europ is the big country
Explanation:
Answer:
B) central-route processing
Explanation:
Robert has developed a favorable attitude toward a brand of stationery known as Impress because the brand is eco-friendly and promotes sustainability. He has since learned, through his own research, that Impress also engages in fair trade practices. Robert's attitude formation is an example of <u>central-route processing</u>. Central-route processing is a type of processing of information and attitude formation that relies on an individual's ability to carefully and correctly evaluate the arguments in a persuasive message.
Robert is able to evaluate the message and arguments on sustainable environment and hence forms his decision towards favouring the Impress brand because of their eco-friendly practices.
