If 200. g of liquid water at 0 °C and 12.7 g of steam at 100.0 °C are mixed in an insulated container, what will the final temperature be?
Given Information: Specific heat of ice 2.09 J/g °C Heat of Fusion for ice at 0°C 334 J/g Specific heat of liquid water 4.184 J/g °C Heat of Vaporization of liquid water at 100°C 2.26 ? 103 J/g Specific heat of steam 2.03 J/g °C
Nonmetals like C,N,S and P are typically the central atom in a molecular compound rather than nonmetals such as O,F,H and Cl. One reason for this is
