Question:

Given the equation {eq}2 Mg + O_{2} \rightarrow 2MgO {/eq}, how many moles of MgO are produced for every mole of oxygen gas used up?

Burning Magnesium:

Burning magnesium is a common chemistry demo and common experiment for learning to determine empirical formulas. Safety precautions do need to be taken because the reaction is very exothermic and the intensity of the flame can cause damage to eyesight. Thus students generally look away or look through filters to observe the reaction.
