First we must write out the equation then balance it. When we balance the equation, the coefficient that represents potassium chloride will be the number of the moles it has.

Solid potassium chlorate decomposes to produce solid potassium chloride and oxygen gas.

1KClO3 → 1KCl + 1O2

To balance the equation, we must make sure each element has the same amount of atoms on both sides of the equation. We can see that there is 3 oxygen in KClO3 (potassium chlorate) and 2 oxygen in O2 (oxygen gas). We multiply potassium chlorate by 2 and oxygen gas by 3 giving us:

2KClO3 → 1KCl + 3O2

Now we have 2 moles of potassium chlorate and 3 moles of oxygen gas. The KCl (potassium chloride) is now unbalanced. Since there is 2 moles of potassium chlorate there will also be 2 moles in KCl, so we multiply KCl by 2 giving us:

2KClO3 → 2KCl + 3O2

Remember the coefficient that is next to compound in the equation represents the amount of moles.

The answer is 2 moles of potassium chloride.

Answer from: Quest

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

Answer from: Quest

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
