When NaOH(aq) and CaCO3(aq) are mixed what precipitate forms and what color
same question with
NaOH and KCl
NaOH and K2CrO4
CaCO3 And KCl
CaCO3 and AgNO3
CaCO3 And K2CrO4
KCl And K2CrO4
AgNO3 and K2CrO4
I am having trouble making my table of knowns for a qualitative analysis lab, if someone could do at least some of these it would be very helpful.

NaOH(aq) + CaCO3(s) ==> Nothing happens
NaOH(aq) + KCl(aq) ==> Nothing happens
NaOH(aq) + K2CrO4(aq) ==> Nothing happens
CaCO3(s) + KCl(aq) ==> Nothing happens
CaCO3(s) + AgNO3(aq) ==> Nothing happens
CaCO3(s) + K2CrO4(aq) ==> Nothing happens
KCl(aq) +K2CrO4(aq) ==> Nothing happens, unless heated in acidic environment
2AgNO3(aq) + K2CrO4(aq) ==> 2KNO3(aq) + Ag2CrO4(s)(red)
