<u>Answer:</u> The balanced chemical equation is 
<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:

<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
and
. Also, a coefficient of 3 must be written infront of 
For the balanced chemical equation:

The temperature of the gas, the hotter they get the faster they move. the colder they get, the slower they move
If you are talking about at the beaches waves would cause increased abrasion because the force of a wave hitting a rock or something else will slowly cause the object to wear away. Also strong winds could cause increased abrasion because the wind could pick up small sand particles that will slowly erode the thing it hits.
Answer:
Things like salt, sugar and coffee dissolve in water. They are soluble. They usually dissolve faster and better in warm or hot water. Pepper and sand are insoluble, they will not dissolve even in hot water.
