A0.600-kg piece of metal x is heated to 100â°c and placed in an aluminum can of mass 0.200-kg which contains 0.500 kg of water initially at 17.3â°c. the final equilibrium temperature of the mixture is 20.2â°c, what is the specific heat of metal x? the specific heat of aluminum is 910 j/kg â k.

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.

An alkaline battery produces electrical energy according to the following equation. zn(s) + 2 mno2(s) + h2o(l) zn(oh)2(s) + mn2o3(s) (a) determine the limiting reactant if 17.5 g zn and 31.0 g mno2 are used. (type your answer using the format ch4 for ch4.) (b) determine the mass of zn(oh)2 produced. _ g
