Answer:
Explanation:
We want the energy required for the transition:
CO 2
(
s
)
+
Δ
→
C
O
2
(
g
)
Explanation:
We assume that the temperature of the gas and the solid are EQUAL.
And thus we simply have to work out the product:

1 to get an answer in Joules as required.
What would be the energy change for the reverse transition:
C
O

+
→
C

?
Answer:
8.33 moles CO2 X. 25mol O2. 16mol CO2. = 13.0 moles
Answer:
The Law of Definite Proportions ensures that chemical compounds are always created using the same proportions, regardless of the amount of the compound which is being made
Exothermic processes: Making ice cubes,formation of snow in clouds
Endothermic processe: Melting ice cubes, evaporation of water
