in an experiment magnesium ribbon was heated in air the product formed was found heavier than original ribbon.potassium manganate(vii)was heated im air and product formed was found lighter.explain different observations made​

Respuesta :

Answer:

1: due to difference in reactivity and melting point

2 during the reaction both combine with oxygen in this case magnesium remain solid but some potassium vaporise

The burning of Magnesium ribbon in the air is a chemical change.

What are the observations made?

  • Magnesium is a chemical element with the symbol Mg and atomic number 12.
  • It is a shiny gray solid that shares many physical and chemical properties with the other five alkaline earth metals.
  • Magnesium is a silvery-white metal.
  • Magnesium burns in the air in the presence of oxygen in the form of Magnesium oxide.

            2Mg (s) + O2 (g) ⇒ 2MgO (s)

  • There is a direct combination reaction of two elements Mg and O2.
  • Magnesium oxide (MgO) is basic in nature.
  • Formation of MgO is a chemical change.
