2Al(No3)3(aq) + 3Ba(OH)2(aq) ------------> 2Al(OH)3(s) + 3Ba(NO3)2(aq)
Ca(s) + ZnBr2(aq) -------------------> Zn(s) + CaBr2(s)
CuSO4(aq) + Na2S(aq) --------------> CuS(s) + Na2SO4(aq)
KBr(aq) + Pb(Cl3)2(aq) -----------------> PbBr2(s) + K(ClO3)(aq)
“I have a dream”
One of MLK’s famous quotes, he says this while fantasizing of a reality where apartheid did not exist. He had a dream, and because he did, we could all too.
