Question

help please

Balance the following redox reaction in acidic solution. NO(g)+Zn2+(aq) → NOZ (aq)+Zn(s) - NO(g) + Zn²+ (aq) → NO, (aq) + Zn(s)

Answer 1

ANSWER IS --

2NO(g) + 3Zn2+ (aq) + 4H2O  $\rightarrow$ 2NO3- (aq) + 3Zn (s) + 8H+

STEP BY STEP EXPLANATIONS ARE GIVEN BELOW

Step-1 ! Write down the unbalanced equation of the chemical reaction: - an?*(22) + NOCY) = N03 + In () step-2! Separate the po Separate the process into half reaction. A redox reaction is nothing but both oxidation and reduction reaction. taking place simultane of 2 - 2 24 m (ar) (+5) (2-) sog. & no of N OC Rednetion half a reaction. Tnt (as) at 20 m (s). ( electron goin is rednetion). Oxidation half - reaction! No ze – No ( electron loss oxidation),

Step-3! Balonce the atoms in each eaction. A chemical equat must have the same number of atoms of each element on both sides of the equation. & Balance all other atoms and elections eges except hydrogen and oxygen? R: 2021 & 2e en (D x 3 O: No-3e Noo (1) x2 For balaneing alongepor elechron) multiplying equation lig by 3 and equation (ii) by 2 as follows a w P: 0: 32m2 + + 62 ->32 2 No abe 200 - (n) Add the aboveo equations (i) andling 280 2t & 68 +2 No

* egnation Balance the - (1) by adding oxygen atoms in H 2 ho. 2 No - 60 4440 2002 + 844 Equation aliii) remain same became there no oxygen and hydrogen atome present. I. Add the half - reaction together. The two half requation (egn- (v. and equation - (iii) , can be combined just like two algebric equations, with the arrow serving as the equal sign. Recombine the two half-reactions by adding all the reactants together on and one side all of the products together on the other side. 200 - betuhot 32n2 ft be ~ 2 No 3 + 32 +817 step.5. Simplify the equations. The same species on opposite sides of the arrow and the same species with opposite side of the same side of the arrow can be canceled . 2 NO GO+ 420 of 3202 ) 2 2NO3 +3m(s) +8H

to & Verify that the sum of I the onation charges on one side of the equat bequal to the sum of the charges an the other side. 2x0 + 440 + 362) = 24-1) 4340 + 8x(+1) Ofo of 6 – – 2 tot 8 2 +6 tf (verified) . Since the charges on both sides are equal we can write the balanced equation: - 3 7 24 42 00 +440 x 200 7 3 2n 48 HP CNB According to the given question we can me use single arrow instead of both side arrow but in redor reaction both side arrow in prefered.) .
