What is the balanced equation for MG o2 MgO?

Example

Step	Result
1	magnesium + oxygen → magnesium oxide
2	Mg + O 2 → MgO
3	reactants: 1 × Mg, 2 × O products: 1 × Mg, 1 × O Not balanced.
4	Mg + O 2 → 2MgO

What type of reaction is MgO –> mg o2?

exothermic reaction
Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.

What is the total number of mole ratios of reaction between MG and HCL?

A balance chemical equation shows the ratio in which substances react and are produced. This is called the stoichiometry of a reaction. This balanced chemical equation shows that 1 mole of magnesium reacts with 2 moles of hydrochloric acid to form 1 mole of magnesium chloride and 1 mole of hydrogen.

What is the limiting reactant 2Mg s )+ o2 G → 2MgO s?

Magnesium is the limiting reactant.

Why mg O2 is MgO?

As magnesium (Mg) has a valency of +2, and oxygen (O) has a valency of -2, the ratio would be 1:1, and magnesium oxide would be represented as MgO.

How many moles of O2 are needed to form 2 moles of MgO 2 Mg O2 2?

Chemical Reactions and Moles of Reactants and Products That is, it requires 2 moles of magnesium and 1 mole of oxygen to produce 2 moles of magnesium oxide.

Which reactant is the limiting reagent if there is 1 g of both c6h12o6 and O2?

If more than 6 moles of O2 are available per mole of C6H12O6, the oxygen is in excess and glucose is the limiting reactant. If less than 6 moles of oxygen are available per mole of glucose, oxygen is the limiting reactant. The ratio is 6 mole oxygen per 1 mole glucose, OR 1 mole oxygen per 1/6 mole glucose.

Is 2Mg O2 2MgO exothermic?

2Mg+O2–> 2MgO + Heat. This is an exothermic reaction.
