Don't know what your asking there. The double bond between oxygen atoms is stretched and breaks forming two MgO. Mg + 1/2 O2 ---> MgO is correct reaction equation. Lv 7. round to one decimal place A) 2Mg + O 2 → 2MgO B) CaCO3 →CaO + CO 2 C) 2NO + O2 → 2NO 2 D) 2NaHCO3 + H 2 SO 4 → Na 2 SO 4 + 2H 2 O + CO 2 2. We only see the reactants and the products, but some really interesting chemistry takes place between them. 0.80 Mole. So then that makes the balanced equation 2Mg + O2 --> 2MgO. Mg + O=O --> Mg-O=O ...... a bond between Mg and O2 is formed, Mg + Mg-O=O --> Mg-O=O-Mg ....a bond between Mg and MgO2 is formed, Mg-O=O-Mg --> 2 MgO ..... a bond between two oxygen atoms is broken. V2O5 + 5CaS → 5CaO + V2S5. a) mg(s) + o2(g) → mgo(s) b) 2mg(s) + o2(g) → 2mgo(s) c) 2mgo(s) → 2mg(s) + o2(g) d) 2mg(s) → 2mgo(s) + o2(g) - e-eduanswers.com Al. When a 2 is placed in font of the Mg on the left side, the equation reads 2Mg + O2 ( 2MgO. 2Mg(s)+O_2(g)->2MgO(s) Now, there are equal amounts of magnesium atoms and oxygen atoms on both sides, and so the equation is balanced. Answer: 1 on a question Which equation is balanced? You can use parenthesis or brackets []. Experts are waiting 24/7 to provide step-by-step solutions in as fast as 30 minutes!*. What is the oxidizing agent and reducing agent. I got: Mg+O2 -> MgO2 2Mg+O2 -> 2MGO Both may or may not be right so if its neither please put the correct answer. Mg + O2 → MgO Step 3: Balancing the equation On the left we have 2x O so on there right, we should mulitply MgO by 2 so we have on each side 2x O Mg + O2 → 2MgO On hte right side we have 2x Mg, so we have to multiply on the left side Mg by 2 to have the same amount of Mg on both sides 2Mg + O2 → 2MgO Now the equation is balanced Come apart easily, it takes a great deal of energy products are enter reagents and!
