Question

Answer 1

\(CTTQ:Zn_x^{II}\left(OH\right)_y^I\\ \rightarrow x\cdot II=y\cdot I\rightarrow\dfrac{x}{y}=\dfrac{1}{2}\rightarrow x=1;y=2\\ \rightarrow Zn\left(OH\right)_2\\ CTTQ:Ba_x^{II}\left(CO_3\right)_y^{II}\\ \rightarrow x\cdot II=y\cdot II\rightarrow\dfrac{x}{y}=1\rightarrow x=1;y=1\\ \rightarrow BaCO_3\\ CTTQ:Al_x^{III}\left(NO_3\right)_y^I\\ \rightarrow x\cdot III=y\cdot I\rightarrow\dfrac{x}{y}=\dfrac{1}{3}\rightarrow x=1;y=3\\ \rightarrow Al\left(NO_3\right)_3\)

Answer 2

Zn(OH)₂

Ba(CO₃)

Al(NO₃)₃
