Answer:
3Mg + Fe₂O₃ → 3MgO + 2Fe.
Explanation:
3Mg + Fe₂O₃ → 3MgO + 2Fe.
That 3.0 mole of Mg react with 1.0 mole of Fe₂O₃ to produce 3.0 moles of MgO and 2.0 moles of Fe.
Mg (3), Fe (2), and O (3).
made up of what?
Many insulating materials contain spaces filled with air because ; Air is a poor conductor of heat and electricity
Insulators are materials that do not allow the easy passage of heat or electricity through them. they are used to protect users from direct exposure to electricity and heat and also for the protection of equipment's at home and at work places.
Insulators are generally bad conductors of heat and electricity. some examples of insulators are ;
They are all very good insulators. but the most commonly used insulator in electrical installations is Porcelain
Hence we can conclude that many insulating materials contain spaces filled with air because Air is a poor conductor of heat and electricity.

Answer:
this can be explained in terms of the Law of Conservation of mass because you just have to multiply the number of amount that was lost during the fire by 5
Explanation:
so if they lost 489 miles of mass from the fire, then u will have to multiply 489 by 5. 489x5=2445
