Lose electrons - electrons want to fill their outer valence shell, so sometimes instead of gaining it is easier to lose some and have a filled outer shell
500 grams Calcium Nitrate to mol= 3.04715
<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
