For the reaction 2NO + O2 = 2NO2, what is the maximum amount of NO2 (46.0055 g/mol) which could be formed from 8.6g of NO (30.0061 g/mol) and 1.78g of O2 (31.9988 g/mom)?

The elements in a Periodic Table are grouped according to their classifications. The major classifications are Metals, Non-metals, and Metalloids. Their level of reactivity can be gauged by simply looking at their position in the table. For Metals, their reactivity increases as you move to the left then going down. Non-metal reactivity increases as you move to the right then going up, starting at the bottom of the table.
