Question

in the following equation xNO+yO2-zNO2, x+y-z is​

Answer 1

Answer:

x + y - z = 2 + 1 - 2

= 1

Step-by-step explanation:

$x (NO) + y (O_{2})$   ⇒ $z(NO_2)$

LHS:                         RHS:

N - 1 =>2                   N - 1 =>2

O - 3 =>4                  O - 2 =>4

Now replace

x with 2

y with 1

z with 2

Now the equation is balanced; i.e. ,

$2 (NO) + 1 (O_{2})$  ⇒ $2(NO_2)$
