A given quantity of electricity was passed through electrolytic cells connected in series containing solution of Silver trioxonitrate v, Copper ii, tetraoxosulphate vi and Sodium Chloride respectively. If
10.5g of Copper are deposited in the second electrolytic cell. Calculate (a)the mass of silver deposited in the first
cell (b)the volume of Chlorine liberated in the third cell at 18°C and 740mmHg pressure [Ag= 108g/mol, Cu =
63.6,/mol, IF-95600C, Molar volume of gas S. T.P =22.4dm

98 ! and brainliest plz ! the below reaction can be categorized as more than one type of reaction. which reactions are these, and what are the types of reactions?

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
