Answer: a) 0.070 moles of oxygen were produced.
b) New pressure due to the oxygen gas is 2.4 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = 2.7 atm
V = Volume of gas = 700 ml = 0.7 L
n = number of moles = ?
R = gas constant =
T =temperature = 329 K
Thus 0.070 moles of oxygen were produced.
When the 700 mL flask cools to a temperature of 293K.
The new pressure due to the oxygen gas is 2.4 atm

Answer:
The correct option is: c. Mercury is closer to the Sun
Explanation:
Mercury is the first and the smallest planet of the Solar system that is present <u>closest to the Sun</u>. The surface temperature of this planet ranges from -173 °C-427 °C or 100-700 K.
Due to the small size and high surface temperature of the planet, the gravity can not retain a significant atmosphere.
Whereas, Moon is the only permanent <u>natural satellite of the planet Earth.</u> It is the second most brightest object in the Earth's sky after Sun.
<u>Since Mercury is much closer to the Sun than the Moon. Therefore, Mercury is much hotter than the Moon.</u>
