How many mole(s) of oxygen gas (O 2) are needed to react with 4.0 moles of Mg? 6.08 g of magnesium reacts with 4.00 g oxygen to produce magnesium oxide, MgO. magnesium + oxygen → magnesium oxide . Some metals will react with oxygen when they burn. Answers: 2. continue. The magnesium reacts with oxygen to produce the oxide. Students should all be standing and should wear eye protection. Twenty-four grams of magnesium metal reacts with sixteen grams of oxygen gas to form magnesium oxide. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. it continues to burn and forms a compound Y. fullscreen . When magnesium oxide is burnt in air, an oxidation of the magnesium and reduction of some of the oxygen in the air occurs according to the equation:2 Mg + O2 -> 2 MgO. Identify the correct balanced chemical equation that describes this process 2 Mg(s) +20 (9) Mg2O2 (s) Mg(s) + 02 (9) + MgO2 (s) 2 Mg(s) + 02 (9) 2 MgO Mg(s) + 03 (9) + Mg03 (8) 275 nts mestien 17 go 0 (8) o Mg(s) + 03 (9) Mg03 (8) Question 17 3.75 pts How many carbon atoms are there in 52 … When iron metal reacts with oxygen, the reaction can form Fe2o3 (numbers are subscripts). Students see there is an increase in mass and can use the results to find the formula of magnesium oxide The practical activity takes around 30–45 minutes, depending on the competence of the class. Magnesium reacts with oxygen to form magnesium oxide according to the following reaction: 2 Mg + O2 2MgO (a) What is the oxidation state of magnesium in Mg?
