1.
a, \(Natri+sulfuric\:acid\rightarrow Natri\text{ }sulfat+Hidro\)
b, PTHH: \(2Na+H_2SO_4\rightarrow Na_2SO_4+H_2\uparrow\)
Câu 1:
\(a,\) sodium + sulfuric acid ---> sodium sulfate + hydrogen
\(b,2Na+H_2SO_4\to Na_2SO_4+H_2\)
Câu 2:
\(a,\) iron sulfate + barium chloride -----> barium sulfate + iron chloride
\(b,Fe_2\left(SO_4\right)_3+3BaCl_2\to3BaSO_4\downarrow+2FeCl_3\)
