Neptune planet has the coldest surface temperature
<u>Explanation:</u>
With temperatures falling to -218°C in Neptune’s upper atmosphere, the planet is one of the coolest in our Solar System. Neptune is the most faraway planet from the sun. Astronomers have speculated that Neptune's huge internal temperature and the transfer of heat between the core and outer layers might be the cause why Neptune isn't significantly more chill than Uranus.
Pressures in this area range between 1 and 5 bars and the temperature reaches a high of 72 K. At this temperature, states are becoming for methane to condense, and clouds of ammonia and hydrogen sulfide are thought to form. At its core, Neptune reaches temperatures of up to 7273 K which is equivalent to the surface of the sun.

Answer:
1.04 mol
Explanation:
CO₂ is produced in a closed 100 L vessel according to the following equation.
CaCO₃(s) ⇄ CaO(s) + CO₂(g)
At equilibrium, the pressure of carbon dioxide remains constant at 1.00 atm.
First, we need to conver the temperature to the absolute scale (Kelvin scale) using the following expression.
K = °C + 273.15
K = 898°C + 273.15
K = 1171 K
Now, we can find the moles of carbon dioxide using the ideal gas equation.
