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:
A. a market economy
Explanation:
A market economy uses supply and demand to control prices. For example, if the supply is low and demand is high, then the prices will be high and vice versa. This causes competition between companies and offers consumers different choices to buy from. Additionally, this type of economy has low government control giving citizens more freedom.
Answer:
The kind of question asked is open ended question.
Explanation:
An open-ended question is a type of question whose answer cannot be either a "yes" or "no".
It is a question with a detailed answer which would include the feelings or knowledge of the one who is answering. It is possible that the questioner compares the response of the open-ended question with the information he knows. The given question asking the experiences during the first year in college will be a detailed answer given. So, it is an open-ended question.
After the death of Muhammad, he was succeeded by 'the <em>Rashidun</em>', a 30-year reign of the four 'rightly guided caliphs'. During such reign, which lasted from 632 CE to 656 CE, the expansion through the territories outside Arabia started.
Eventually, under the influence of the political systems of these territories, the leadership became hereditary, and the Umayyad dinasty, who moved to Damascus to excercise power, ruled from 661 CE to 750 CE. This dinasty achieved the greatest expansion of the Muslim Empire in a lapse of 89 years, converting the Caucasus, Transoxiana, Sindh, the Maghreb, and the Iberian Peninsula to Islam, as well as occupying 5.79 million square miles of territory and including 62 million people. It was the fifth largest empire in history regarding area and proportion of the world's population.
