D because Carbon and Oxygen form covalent compounds. I wasn't the greatest at chem., but I'm pretty sure this is correct :D let me know if I gave you the right answer.
<h3>
Answer:</h3>
12,281.6 Joules
<h3>
Explanation:</h3>
- The amount of heat energy is calculated by multiplying the mass of a substance by its specific heat capacity and then by the change in temperature.
In our case;
Mass of water vapor, m = 190.0 g
Change in temperature, Δt = 150°C - 118°C = 32°C
Taking the specific heat capacity of water vapor = 2.02 J/g°C
Therefore;
Amount of heat = 190.0 g × 2.02 J/g°C × 32°C
= 12,281.6 Joules
Hence, the amount of heat needed is 12,281.6 Joules
