Question

complete the following reactions 1 ) Sn+ 2NaOH+H2O➡️?
2) Fe+XH2O+3O2➡️?
3) Cu+AgNO3➡️?+?
4) 2HgS+30(2)➡️?+?

Answer 1

hey mate
1) Na2[Sn(OH)4] + H2

2) 2Fe2O3 xH2O 
3).  Ag + CuNO3 
4) ....
hey mate hope it's helpful you

Answer 2

$\huge\mathfrak\red{Answer :}$


1) $2NaOH\:+\:H_{2}O$ ----> $Na_{2}[Sn(OH_{4})]\:+\:H_{2}$

2) $4Fe\:+\:xH_{2}O\:+\:3O_{2}$ -----> $2Fe_{2}O_{3}.3H_{2}O$

If you want to balance it... then at first put value of x = 6 on reactant side...

And x = 3 on product side...

3) $Cu\:+\:2AgNO_{3}$ ----> $Cu(NO_{3})\:+\:2Ag$

4) $2HgS\:+\:3O_{2}$ ----> $2HgO\:+\:2SO_{2}$
