How may grams of oxygen gas reacted with magnesium?
Our final answer is 7.78 times 10 to the negative second power grams of O2, which is the amount in grams of oxygen gas necessary to completely react with the atoms of magnesium.
When magnesium reacts with oxygen Why does the mass increase?
The increase in mass is due to the fact that oxygen from the air has combined with the magnesium to make magnesium oxide, MgO. The chemical equation,Mg+O2→MgO shows this reaction but it needs to be balanced to make 2Mg+O2→2MgO.
What is the mass of oxygen that reacted with the magnesium?
6.08 g of magnesium reacts with 4.00 g oxygen to produce magnesium oxide, MgO.
What mass of oxygen reacts with 12 g of magnesium?
8g
Ans: Magnesium (Mg) and Oxygen (O) combine in the ratio = 3:2 to form compound magnesium oxide (MgO). It follows Law of Constant proportions. 3g of Mg combines with = 2g of O. 12g of Mg combines with = 2 × 12/3 = 8g of O.
What group does magnesium react with oxygen?
Magnesium is group 2, iron is group 8 and copper is group 11. This is important as elements in the same group will react similarly. In these reactions, the elements that react with oxygen are all metals.
What happens when oxygen reacts with Group 2 metals?
In the formula, M represents a metal atom and O represents oxygen. We can therefore say that metals from Group 2 will react with oxygen and have the following general equation, where M represent a Group 2 metal: Metal oxides of the types M 2 O 3 and MO 2 also occur, but we will limit our discussion to the first two types.
What is a metal-oxygen reaction?
As we will see later when we draw diagrams and write formulae to represent these reactions, they are compounds in which a metal is combined with oxygen, in some fixed ratio. The metals will react similarly with the other elements in the same group as oxygen (group 16).
What is the reaction between calcium and oxygen?
As we have said, the metals in the same group will react in the same way as each other with oxygen. So, calcium reacts with oxygen in the same way as magnesium reacts with oxygen. The chemical equations also show similarities. The chemical equation for the reaction between calcium and oxygen is: What is the product called in this reaction?
