Answer:
Sodium peroxide can be prepared on a large scale by the reaction of metallicsodium with oxygen at 130–200 °C, a process that generates sodium oxide, which in a separate stage absorbs oxygen: 4 Na + O2 → 2 Na2O. The ozone oxidizes the sodium to form sodium peroxide.
Answer:
Heat energy is transferred to cooler objects to reduce the temperature of those objects.
Explanation:
The fourth option is not correct.
A correct way of writing it would be : " Heat energy is transferred from cooler objects to reduce the temperature of those objects.". When an object loses heat energy, its temperature reduces. Conversely, when an object receives heat energy, its temperature increases.

Answer:
557.3J is the work of expansion of the CO2 gas
Explanation:
The work of expansion of a gas under constant temperature and pressure (Isobaric pressure) is:
W = P*ΔV
<em>Where W is work</em>
<em>P is pressure = 1.0atm</em>
<em>ΔV = Final volume - Initial Volume = 6.5L - 1.0L = 5.5L</em>
<em />
Replacing:
W = 1.0atm*5.5L
W = 5.5atmL
In Joules (1atmL = 101.325J):
5.5atmL * (101.325J / 1atmL) =
<h3>557.3J is the work of expansion of the CO2 gas</h3>
