Question

7.97 Balance each of the following by adding coefficients, and identify the type of reaction for each: - + O 7.99 If red spheres represent oxygen atoms, blue spheres represent nitrogen atoms, and all the molecules are pases A. Write the formula for each of the reactants and products. B. Write a balanced equation for the reaction. C. Indicate the type of reaction as combination, decomposition, single replacement, double replacement, or combustion.

Answer 1

EU sphere as I atom of 5 let's denote 1 blue sphere as I atom of a I pink sphere as I atom of B ohen forst reaction can be wrritten as A + B) - > AB reson balancing above reaction we get A2+B > 2AB The above reacson is a combination reaction as two molecules are combining to give a product, ③ Here also let's denote 1 blue sphere as i atom A and pink sphere as I cetom of B one reaction can be written as A B - A + BLA om at upon balancing above reaction we gee 1 24,8 -> 242 + B2 The above reaction is a decomposition reaction) as one reactant is breaking into two different borduus.

69 A. Given red spheres represent oxygen avoms. oue spheres represent nitrogen atoms. By looking at figure formula of reactants = No ₂ (1 bluetired; zred) formula of products - NO₂ (nitrogen and zoxygen ( I blue +2red ) aronus are present in Basic reaction is caich meie ule)). Norgh+ 019) N0249) Balanced reaction is NOEG) + 0,19) ► 200,193 The above reaction is a type of combination reactton as moleculea of NO and O2 are Combining to give No C. Scanned with CamScanner
