BRONSTED ACIDS AND BASES IN ORGANIC CHEMISTRY. 1  You should know that Bronsted-Lowry acids are proton donors, and Bronsted bases are proton acceptors. 2  You should be able to write simple Bronsted acid/base equations using curved arrows to show electron flow.
Calculate the amount of heat energy required to condense steam at 100 C,cool liquid and freeze it at 0 C. Share this answer and help others! When 1g of steam at 100 ÂºC condenses to give 1 g of water at 100 ÂºC, 2260 J of heat will be released to the surroundings. So find the heat released when 95g of steam changes. Specific heat of water = 4.18 J/gÂ° C. So multiply 4.18 by 95 (for mass of water) and by 100 (for temp change) Heat of fusion of water = 334.0 J/g (check this data). You have 95g so multiply it by 95. Add the three steps together to get total energy released.
What determines the temperature of condensation or sublimation is the amount of moisture in the air, the greater the amount of water vapor, the higher the condensation temperature. During summer it is not uncommon to have a dew point of 70Â°F in the eastern United States.
