Question

Complete the reactions and blanace them please
​

Answer 1

Explanation:

Apply The Rules of balancing the chemical reactions

$\implies{\bigstar{\mathsf{}}}$First, write the correct formulas for all the reactants and products in the reaction.

$\implies{\bigstar{\mathsf{}}}$ Then ,try to change the coefficients of the reactant and the products, not the subscripts in the formula.

$\implies{\bigstar{\mathsf{}}}$And, cross check that the number of atoms of the element is the same on both the sides of the equation.

$\implies{\bigstar{\mathsf{}}}$Make sure the mass should be balanced.

$\boxed{\mathsf{4Zn + No^{-}_3 + 10H^{+} \longrightarrow 4Zn^{2+} + Nh^{+}_4 + 3H_2o}}$

2]

$\boxed{\mathsf{Cr_2O^{2-}_7 + 3C_2H_4O + 8H^{+} \longrightarrow 2Cr^{3+} + 4H_2O }}$
