Balance the equation mg no3 2 forms mgo plus no2 plus o2?
The balanced equation for the reaction is: 2 Mg(NO3)2 → 2 MgO + 4 NO2 + O2
Write a balanced symbol equation for the reaction between magnesium and oxygen to form magnesium oxide?
I'm not entirely sure but an unbalanced equation is: Mg + O2 -----> MgO
How many atoms of oxygen are there on each side what chemical equation 2 Mg plus O2 - MgO?
There are 2 atoms of oxygen on the left side of the equation (from O2) and 2 atoms of oxygen on the right side (from MgO).
How many grams of oxygen are needed to react with 21.0 g of Mg?
The balanced chemical equation for the reaction between Mg and O2 is 2Mg + O2 -> 2MgO. This equation shows that 1 mole of Mg reacts with 1 mole of O2. The molar mass of O2 is 32 g/mol. Therefore, 21.0 g of Mg will react with 16.0 g of O2, which is 0.5 moles of O2.
What is number of moles of oxygen gas needed to react with 4.0 moles of Mg?
The balanced chemical equation for the reaction between magnesium (Mg) and oxygen (O2) is: 2Mg + O2 -> 2MgO From the balanced equation, it is clear that 1 mole of Mg reacts with 1/2 mole of O2. Therefore, if 4.0 moles of Mg reacts, you would need 2.0 moles of O2.
