A calorimeter has a heat capacity of 320 cal K -1 and contains 718 g of water. Initially the apparatus is at 22.0 o C and contains 1.50 g of ethyl
alcohol, C 2 H 5 OH, in oxygen. If the heat of combustion of ethyl alcohol is
-328 kcal mole -1 , what will be the temperature of the calorimeter when
combustion is complete?

Write skeleton equations for the following reactions c. aluminum(s)+copper(i) chloride(aq) > aluminum chloride(aq)+copper(s)

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Vi limitens. vastery test select the correct answer. which statement explains why large atoms are more reactive than small atoms? a. large atoms have valence electrons farther from the nucleus and lose them more readily. b. large atoms have greater ionization energy, which they can utilize during a reaction. c. large atoms have a greater number of electrons that they can lose during a reaction. d. large atoms have more energy levels, so they have more energy to pass on in a reaction. reset next
