If purple spheres represent iodine atoms, white spheres represent hydrogen atoms, and all the molecules are gases,

c. indicate the type of reaction as combination, decomposition, single replacement, double replacement, or combustion.

Accepted Answer

Hello. In this problem, we are told light gray spheres are chlorine atoms, blue spheres are nitrogen atoms, orange spheres are oxygen atoms and the molecules involved are gasses in the reaction represent below. We are asked to determine the type of chemical reaction we are provided with four possible answers. Answer A states, single displacement B is double displacement C is combination and D is decomposition. Looking at the pictures of our reactants and products, we see that our reactants, we have two molecules that contain one nitrogen, one oxygen and one chlorine. This is referred to as nitros chloride. On the product side, we have one nitrogen molecule, we have one chlorine molecule and we have one oxygen molecule writing our balanced reaction. We then have two molecules of Nitrol chloride going to form one molecule of nitrogen plus one molecule of chlorine plus one molecule of oxygen. So looking at our possible answers, a single displacement reaction, we would have an element and a compound on both the reactant and product side. In this case, we don't have a element on the reactant side and we don't have any compounds on the product side. So answer a is incorrect answer. B A double displacement reaction, we would have two compounds on both the reactant and the product side. And we do not have two compounds on both the reactant product side. So answer B is incorrect answer C is combination in a combination reaction, we have two or more substances combining to form one. So if we look at our reaction, this is the reverse of the reaction as it's written. So that's also incorrect. The last answer, then answer D says decomposition. So this is our correct answer. So we have one substance then breaking down to form three simpler substances. Thank you for watching. Hope this helped.
