I AM SO CONFUSED PLEASE HELP:( When ice at 0°C melts to liquid water at 0°C, it absorbs 0.334 kJ of hear per gram. Suppose the heat needed to melt 49.5 g of ice is absorbed from the water contained in a glass. If this water has a mass of 0.219 kg and a temperature of 21.0°C, what is the final temperature of the water? Assume the specific heat is that of pure water, 4.18 J/(g-°C). (Note that you will also have 49.5 g of water at 0°C from the ice.)

Acetic acid, hc2h3o2, dissolves and completely dissociates in water and a solvation sphere of water molecules forms around the ions. this solute-solvent interaction

Subduction zones occur on earth where dense oceanic crust dives under more buoyant continental crust. these boundaries are characterized by a deep ocean trench next to a high continental mountain range, large numbers of earthquakes and volcanoes. all of this is further evidence for the a) big bang theory b) origin of the species eliminate c theory of plate tectonics d theory of natural selection 4 sedimentary rocks found high in the himalayen mountain

Which reason best explains why metals are malleable? a)because they have delocalized electrons b)because they have localized electrons c)because they have ionic bonds d)because they have rigid bonds
