Question

a. \(Al_2O_3\) + \(H_2SO_4\) --->

b. \(Fe\left(NO_3\right)_3\) + \(Ba\left(OH\right)_2\) --->

c. \(Ca\left(NO_3\right)_2\) + \(K_3PO_4\) --->

d. \(Ca\left(HCO_3\right)_2\) + \(HCl\) --->

Answer 1

a. + 3 ---> Al2(SO4)3 + 3H2O

b. 2 + 3 --->2Fe(OH)3 + 3Ba(NO3)2

c. 3 + 2 ---> Ca₃(PO₄)₂ + 6KNO₃

d. + 2 ---> CaCl₂ + 2CO₂ + 2H₂O

Answer 2

a, Al2O3+3H2SO4--->Al2(SO4)3+3H2O

b, 2Fe(NO3)3+3Ba(OH)2--->2Fe(OH)3+3Ba(NO3)2

c, 3Ca(NO3)2+2K3PO4--->Ca3(PO4)2+6KNO3

d, Ca(HCO3)2+2HCl--->CaCl2+2CO2+2H2O
