Hope it helps you!!!!

Answer 2

Question:-

980 grams of kclo3 is heated then Oxygen gas is evolved and it is used to react with magnesium to form magnesium oxide?

Answer:-

When potassium chlorate (KClO3) is heated in the presence of manganese dioxide catalyst, it decomposes to form potassium chloride and oxygen gas.

The balanced chemical equation is

2KCLO3-------∆(heat)---------->2KCL+3O2

Question:-

Find the weight of magnesium required for the reaction with oxygen?

Answer:-

Mass magnesium = 2.39 g. Mass magnesium oxide = 3.78 g. So mass oxygen = 1.39 g. Number moles Mg = 2.39/24 = 0.0995.
