Answer:
Hey there can you post the complete question ,i cannot find any element
I don’t know how , what class is it for?
The molar mass of the product is equal to 62g/mol.
<h3>Mole calculation</h3>
To calculate the molar mass of a compound it is necessary to have knowledge of the atomic mass of all the elements involved.
In the case of the question, we have the reaction between flourine and magnesium, which represents the element of group 2 with the presented electronic configuration.
Thus, we have the following reaction:

So, just add the molar masses, having:


So, the molar mass of the product, round to the nearest tenth, is equal to 62g/mol.

Answer:Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
