Lithium: Reacts with oxygen to give 2Li 2 O, lithium oxide. Beryllium is reluctant to burn unless it is in the form of dust or powder. For example, oxygen reacts with solid carbon to form carbon monoxide or carbon dioxide, respectively, as shown below (reaction not balanced): The lighter alkaline earth metals calcium and magnesium also form peroxides, which are used commercially as oxygen sources or oxidizers. Many metals react with oxygen gas to form the metal oxide.For example, calcium reacts as follows:2Ca(s)+ O₂(g)→2CaO(s)You wish to calculate the mass of calcium oxide that can be pre-pared from 4.20 g of Ca and 2.80 g of O₂. Na 2 O 2 along with Li 2 O 2 is used in emergency breathing devices in submarines and spacecrafts. The are crystalline solids and have acidic nature. In terms of calculating the limiting reagent, you have got to work out which reactant (Al or O2) is in shorter supply. moles Ca. With oxygen, it forms Copper Oxide. nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron.. The equation you're looking at says that you if react 4 moles of aluminum (Al) and three moles of oxygen (O2), you'll kind 2 moles of aluminum oxide (Al2O3). Hence, these metal oxides are basic in nature. "Al" + 3"O"_2rarr2"Al"_2"O"_3 Now, since there are 1 and 4 aluminum atoms on each side respectively, change the coefficient on the reactants side to 4. Moles CaO are same since 2 moles Ca produce 2 mols CaO. If it is kept in the open, it can explosively react with moist oxygen, catch fire and form sodium oxide. Mark me as brainliest . The reactions of carbon and sulfur with oxygen are examples of non-metals reacting with oxygen. (a) Write a balanced equation for the reaction.
