Explanation: Let's take this step by step. First, we are looking for two moles of NO₂ This means that we can exclude the first two options since each of them shows only one mole.
Now, the compound we are looking for is NO₂. This means that it has two oxygen moles and one nitrogen mole. You have stated that nitrogen is the blue one. Therefore, the compound we are looking for will be the one having one blue ball (representing nitrogen) and two red balls (representing oxygen).
Now taking a look at the choices, we will find that the last one fits our criteria. 1- It has two moles 2- each mole as two red balls and one blue ball
States that particles are attracts with every other particle. wich force is directily proportional product of two masses and inversely proportional to the distance between the centers.
