Cr+pb(NO3)2 gives raise to Cr(NO3)3+pb
pls give answer step by step

Answer 1

2 Cr2 + 3 Pb(NO3)4 = 4 Cr(NO3)3 + 3 Pb

Answer 2

Answer:

$\small\bf\pink{\mid{\overline{\underline{Balanced\:Equation}}}\mid}$

Explanation:

$Pb(No_{3})_{2}  + Cr = Pb + Cr(No_{3} )_{3}$

$3Pb(No_{3} )_{3}  + 2Cr = 3Pb + 2Cr(No_{3} )_{3}$
