please answer this is dimensional analysis as the problem requires

A vehicle airbag uses a gas generator that contains a mixture of three compounds: NaN,, KNO,, and SiO,. A series of three reactions convert the highly toxic sodium azide, NaN3, into N, gas and harmless silicate glass. The nitrogen gas fills up the airbag, causing it to rapidly expand in a head-on collision. Balance the reactions involved in the deployment of an airbag by inserting the appropriate coefficients. reaction 1: NaN3(s) → Na(s) + N,(g) reaction 2: Na(s) + KNO,(s) → K,0(s) + Na,O(s) + N2(g) reaction 3: K,O(s) + Na,O(s) + SiO,(s) – K,0,Si(s) + Na,O,Si(s)
