Question

write the balanced chemical equation of the following and identity the type of reaction in each case
1} lead nitrate+potassium -potassium iodide+potassium nitrate
2} phosphoric acid +potassium hydroxide -potassium phosphate+water
3} aluminium+sulphuric acide-aluminium sulphate+hydrogen
4] barium hydroxide+ammonium chloride -barium chloride+ammonium hydroxide

Answer 1

Dear student
It should be lead nitrate +potassium iodide
$$\begin{gathered} 1.Pb(N{O}_3{)}_2+2KI\to Pb{I}_2+2KN{O}_3 \\ 2.H_{3}P{O}_4+KOH\to K_{3}P{O}_4+3H_{2}O \\ 3.2Al+3H_{2}S{O}_4\to A{l}_2(S{O}_4{)}_3+3H_2 \\ 4.Ba(OH{)}_2+2N{H}_{4}Cl\to BaC{l}_2+2N{H}_{4}OH \end{gathered}$$
