Diatomic O2 can react with the element magnesium to form magnesium oxide (MgO). The balanced chemical equation is: If 4 moles of magnesium totally reacted with more than enough O2, how many moles of MgO would be expected to form?
1) what mass of oxygen will react with 2.64g of magnesium? 2Mg + O2 -> MgO I was going to do 2.64g * (1/2) from the equation but im not sure. Do I have to add a 2 in front of the MgO? 2) How many moles of sodium ions are
When magnesium oxide (MgO) and water (H20)react, they produce magnesium hydroxide Mg(OH)2. Magnesium hydroxide is a medicine used to treat an upset stomach. The equation for this chemical change is shown below: MgO + H20 -->
Magnesium can be used as a “getter” in evacuated enclosures to react with the last traces of oxygen. (the magnesium is usually heated by passing an electric current through a wire or ribbon of the metal) If an enclosures of
Calculate how many grams of MgO that can be produced from 4.58 of Mg metal and 0.99 of O2 gas. Recall the balanced reaction is: 2 Mg (s) + O2 (g) 2 MgO (s) And the answers to part one were: Moles of MgO from 4.58 g Mg = 0.1884
How would you solve this problem?... magnesium metal reacts rapidly in hot water. Predict the mass of pericipitate that will form if a 2.0g strip of magnesium reacts completely with water. *Use the 5-step method* *Answer: 4.8g* I
