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.
If you also wanted to convert the water to steam, you'd have to add the latent heat of vaporization to that, which is Q = mL. The latent heat of vaporization for water is 2260 KJ/kg, so the additional energy required is (3.785 kg)(2260 KJ/kg) = 8554 KJ, for a total of 9819 KJ.
