Answer:
Mass of carbon dioxide = 7.48 g
Explanation:
Given data:
Mass of lithium carbonate = 12.5 g
Mass of carbon dioxide produced = ?
Solution:
Chemical equation:
Li₂CO₃ → Li₂O + CO₂
Number of moles of Li₂CO₃:
Number of moles = mass/ molar mass
Number of moles = 12.5 g /73.89 g/mol
Number of moles = 0.17 mol
Now we will compare the moles of Li₂CO₃ with CO₂.
Li₂CO₃ : CO₂
1 : 1
0.17 : 0.17
Mass of carbon dioxide:
Mass of carbon dioxide = number of moles × molar mass
Mass of carbon dioxide = 0.17 mol × 44 g/mol
Mass of carbon dioxide = 7.48 g
Warm is less heaver then cold air so warm air rise and cold air sinks

Explanation:
The given data is as follows.
= 1.50 L, 
= 159 K,
= 5.00 atm, 
= 0.2 L,
= ?, 
= 50.0 atm
And, according to ideal gas equation,
Hence, putting the given values into the above formula to calculate the value of final temperature as follows.
= 21.27 K
Thus, we can conclude that the final temperature is 21.27 K
.
It is called nuclear energy.
