Identify the mixture of powdered charcoal and powdered sugar and suggest a technique for separating their components
mihalych1998 [28]
A- Identify the mixture:
The mixture of powdered charcoal and powdered sugar is considered as a homogeneous mixture. This means that you cannot identify the components with naked eye as they are uniformly distributed in the mixture.

B- Separate components:
You ca separate the charcoal powder from the sugar powder using the following steps:
1- add water. Sugar will dissolve in water while charcoal won't.
2- filter the solution where the powdered charcoal will remain on the filter paper and the solution of powder will pass through.
3- boil the sugar solution (above 100 degrees celcius). The water will evaporate and the sugar will precipitate.

<u>Answer:</u> The balanced chemical equation is 2KClO_3(s)\rightarrow 2KCl(s)+3O_2(g)

<u>Explanation:</u>

A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.

For the given unbalanced chemical equation:

KClO_3(s)\rightarrow KCl(s)+O_2(g)

<u>On the reactant side:</u>

Atoms of K = 1

Atoms of Cl = 1

Atoms of O = 3

<u>On the product side:</u>

Atoms of K = 1

Atoms of Cl = 1

Atoms of O = 2

To balance the equation, we must balance the atoms by adding 2 infront of both KClO_3(s) and KCl(s). Also, a coefficient of 3 must be written infront of O_2(g)

For the balanced chemical equation:

2KClO_3(s)\rightarrow 2KCl(s)+3O_2(g)
