DATA & CALCULATIONS:
Mg = 0.20 g.
MgO= 0.5 g.
HCl= 100 ml.
(SP)= 4.184 j/g deg.
HCl with MgO:
Ti =19oC , Tf = 23 oC
= 23 -19 =4 oC.
Ti =20oC , Tf = 25 oC
= 25- 20 =5 oC.

BALANCING REDOX REACTIONS IN BASE SOLUTION
You can balance redox reactions in base solution in almost the same way as if they
were in acid solution. In fact, initially we will assume the reaction is taking place in
acid solution but eventually switch over
