Answer:
Some common compounds in our daily lives:
Water, H2O. We need this for survival, because it serves a lot of functions in our body, such as being a medium for chemical reactions in our cells.
Carbon Dioxide, CO2. It is one of the components of air, our body also produces CO2 during respiration.
Sodium chloride, NaCl. Table salt is mostly made of sodium chloride. It is also found dissolved in sea water.
Methane, C2H4. This is a common fuel for generating electricity. It can also be found (small amounts) in air.
Nitrogen Dioxide, NO2. It can also be found in air, and it is one of the common air pollutants brought by burning of fossil fuels.

Explanation:
The total heat required to convert the ice to steam is 155,000 J.
The given parameters:
- <em>Mass of the ice, m = 50 g</em>
- <em>Initial temperature of the ice, t = -10 ⁰C</em>
- <em>Final temperature of the ice, T = 0⁰C, 100⁰C and 120⁰C</em>
- <em>Specific heat capacity of water = 4.184 J/g⁰C</em>
- <em>Heat of fusion of ice, = 333.55 J/g</em>
- <em>Heat of vaporization, = 2,230 J/g</em>
<em />
The heat required to raise the temperature to 0⁰C is calculated as;

The heat required to melt the ice is calculated as follows;

The heat raise the temperature to 100⁰C is calculated as;

The heat required to boil the water is calculated as follows;

The heat raise the temperature to 120⁰C is calculated as;

The total heat required is calculated as follows;
