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.)

Mitosis is a type of cell division that produces cells that are identical to the parent cell. meiosis is a different type of cell division that produces cells that carry have a genetic material of the parent cell. based on the information provided how do the purpose of mitosis and meiosis differ

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
